【临时解决】webpack打包失败:ERROR in bundle js from UglifyJs Unexpected token punc

Webpack crifan 11454浏览 0评论

一个ReactJS的项目,之前正常运行的。

后来去重新npm install后再去npm run build结果出错:

webpack ERROR in bundle js from UglifyJs

webpack -p outputs: ERROR in bundle.js from UglifyJs Unexpected token: name (login) [./login.es6:2,4] · Issue #3 · joeeames/WebpackFundamentalsCourse

突然发现个问题:

此处自己的

package.json

中的:

“webpack”: “^2.4.1”,

而实际上安装的:

➜  ucowsapp_h5_en git:(master) ✗ webpack -v

3.5.4

是3.5.4

-》估计是webpack不符合版本,所以才出错的?

另外要求的:

“webpack-dev-server”: “^2.4.4”

但是实践上:

➜  ucowsapp_h5_en git:(master) ✗ webpack-dev-server -v

webpack-dev-server 2.9.3

webpack 2.7.0

而node_modules中的版本是符合要求的:

➜  ucowsapp_h5_en git:(master) ✗ ./node_modules/.bin/webpack -v
2.7.0
➜  ucowsapp_h5_en git:(master) ✗ ./node_modules/.bin/webpack-dev-server -v
webpack-dev-server 2.9.3
webpack 2.7.0

所以去把:

package.json

中的:

“dev”: “cross-env NODE_ENV=development webpack-dev-server –inline –hot –progress”,
“build”: “cross-env NODE_ENV=production webpack -p –progress”,

改为:

“dev”: “cross-env NODE_ENV=development ./node_modules/.bin/webpack-dev-server –inline –hot –progress”,
“build”: “cross-env NODE_ENV=production ./node_modules/.bin/webpack -p –progress”,

看看效果。

结果问题依旧。

javascript – ERROR in bundle.js from UglifyJs – Stack Overflow

去加上es2015的modules参数试试

(但是为何之前都一直没问题,现在却出错?)

结果这下问题更大了:

直接连webpack.config.babel.js中的(ES6的)import都无法识别了。

对比之前的正常可以运行的项目,发现webpack版本有点不一样:

➜  ucowsapp_h5 git:(master) ✗ webpack -v
3.5.4
➜  ucowsapp_h5 git:(master) ✗ webpack-dev-server -v
webpack-dev-server 2.5.0
webpack 2.6.1
➜  ucowsapp_h5 git:(master) ✗ npm run build

即虽然配置都是:

“webpack”: “^2.4.1”,
“webpack-dev-server”: “^2.4.4”

能正常运行的版本是:

➜  ucowsapp_h5 git:(master) ✗ webpack -v
3.5.4
➜  ucowsapp_h5 git:(master) ✗ webpack-dev-server -v
webpack-dev-server 2.5.0
webpack 2.6.1
➜  ucowsapp_h5 git:(master) ✗ which webpack
/usr/local/bin/webpack
➜  ucowsapp_h5 git:(master) ✗ which webpack-dev-server
/usr/local/bin/webpack-dev-server

此处出错的:

➜  ucowsapp_h5_en git:(master) ✗ webpack -v
3.5.4
➜  ucowsapp_h5_en git:(master) ✗ webpack-dev-server -v
webpack-dev-server 2.9.3
webpack 2.7.0
➜  ucowsapp_h5_en git:(master) ✗ which webpack
/usr/local/bin/webpack
➜  ucowsapp_h5_en git:(master) ✗ which webpack-dev-server
/usr/local/bin/webpack-dev-server

算了,去试试,把当前

“webpack”: “^2.4.1”,

“webpack-dev-server”: “^2.4.4”

改为此处所需要的:

“webpack”: “2.6.1”,

“webpack-dev-server”: “2.5.0”

重新npm install后:

➜  ucowsapp_h5_en git:(master) ✗ npm install
[email protected] node_modules/resolve-cwd/node_modules/resolve-from
[email protected] node_modules/resolve-cwd

npm WARN [email protected] No repository field.
npm WARN [email protected] No license field.

然后版本貌似一样了:

➜  ucowsapp_h5_en git:(master) ✗ webpack -v
3.5.4
➜  ucowsapp_h5_en git:(master) ✗ webpack-dev-server -v
webpack-dev-server 2.5.0
webpack 2.6.1

再去试试

结果问题依旧。

➜  ucowsapp_h5_en git:(master) ✗ ./node_modules/.bin/webpack -v

2.6.1

那去换成:

“build”: “cross-env NODE_ENV=production ./node_modules/.bin/webpack -p –progress”,

再去试试

问题依旧。

另外也注意到,此处package.json中并没有依赖UglifyJs

所以只是:

webpack内置的UglifyJs插件,去执行对应的优化的

而此处的错误,估计也就是webpack不同,内置UglifyJs版本不同,导致出错的。

webpack ERROR in bundle js from UglifyJs Unexpected token punc

webpack -p outputs: ERROR in bundle.js from UglifyJs Unexpected token: name (login) [./login.es6:2,4] · Issue #3 · joeeames/WebpackFundamentalsCourse

试试:

.babelrc中加上

“compact”: false,

结果:问题依旧。

去掉:

warnings: false

结果:问题依旧。

然后还显示出一堆的warning呢。

我此处是:

有单独的.babelrc,写了配置的:

{
  “sourceMaps”: true,
  “presets”: [
    [
      “es2015”,
      {
        “loose”: true
      }
    ],
    “stage-0”
  ],
  “plugins”: [
    [“transform-decorators-legacy”],
    [“transform-react-jsx”, { “pragma”: “h” }]
  ]
}

同时:webpack.config.babel.js中也有:

      {
        test: /\.jsx?$/,
        exclude: /node_modules/,
        use: ‘babel-loader’
      },

“配置要写在rules里面啊啊啊啊。。。”

不会是:必须把配置写在rule里吧?

去试试:

暂时删除:.babelrc

把上面配置都整合到rules中

      {
        test: /\.jsx?$/,
        // exclude: /node_modules/,
        // use: ‘babel-loader’
        use: {
          loader: ‘babel-loader’,
          options: {
            “sourceMaps”: true,
            “presets”: [
              [
                “es2015”,
                {
                  “loose”: true
                }
              ],
              “stage-0”
            ],
            “plugins”: [
              [“transform-decorators-legacy”],
              [“transform-react-jsx”, { “pragma”: “h” }]
            ]
          }
        }
      },

结果还是无法识别:

webpack.config.babel.js

中的import

/webpack.config.babel.js:1

(function (exports, require, module, __filename, __dirname) { import webpack from ‘webpack’;

                                                              ^^^^^^

算了,把之前环境下的node_modules,全都拷贝过来:

看看能否正常运行。

结果还真的可以:

【总结】

此处,同样的配置:

webpack.config.babel.js

package.json

.babelrc

之前是可以正常编译的,结果显示出错:

ERROR in bundle js from UglifyJs Unexpected token punc

的原因:

本以为是webpack的升级版本,导致不兼容,结果后来换成和另外可正常编译的环境的一样的版本:

webpack-dev-server -v

webpack-dev-server 2.5.0

webpack 2.6.1

也不行。

最后折腾了半天,试了各种参数,都还是无法解决。

最终是:

把之前正常环境下的.node_modules都拷贝过来,暂时凑合继续正常使用

-》如果是另外新的环境

npm install

后,则暂时是无法正常使用的。。。

待后续再想办法吧。

或许以后也就随着webpack发布新版本而就正常了呢。

【后记】

先去:

rm -rf node_modules

重新去用npm install后,先去:

【已解决】npm WARN deprecated [email protected] [email protected]

但是结果还是没有解决此处问题。

所以还是要去一点点对比,看看到底是哪个库的版本不同,导致了此处的问题。

通过:

npm install > npm_install_20171024_1115.log

发现uglify有关的,有几处:

│ │ └─┬ [email protected]
│ │ ├── [email protected] deduped
│ │ └── [email protected]
。。。
│ ├─┬ [email protected]
。。。
│ │ └─┬ [email protected]
│ │ ├── [email protected]
│ │ ├── [email protected] deduped
。。。
│ ├─┬ [email protected]
│ │ ├── [email protected] deduped
│ │ ├── [email protected]

即:

[email protected]依赖了[email protected]

serve依赖handlebars依赖[email protected],依赖[email protected]

[email protected]依赖[email protected]依赖[email protected]

看起来,此处最相关的是[email protected],所依赖的[email protected]

uglify-js现在默认指的是v2 -》 v2的uglify-js是不支持ES6的 -》如果想要支持,则自己去用:uglify-es

根据提示,好像和html-webpack-plugin有关?

再回头看出错信息中,写了:

是html-webpack-plugin处理index.html出错的。

所以很可能是:

[email protected]依赖了[email protected]

依赖了v3的uglify-js导致了此处的问题?

想要去给html-webpack-plugin依赖的uglify-js,降低版本到v2,但是却:

无法降级

因为此处的package.json中并没有指定uglify-js版本,而只是html-webpack-plugin自己依赖的。

vue.js – VUE2打包文件时出错 – SegmentFault

和我遇到问题类似。

但是对方说的“原来上级目录是node_modules会导致文件打包失败,移动到其他目录就可以了”

看不懂。

大概懂了:

其自己的开发路径“/Users/jathon/node_modules/jtools”包含了node_modules

所以换到别的路径,就可以了。

-》我此处没有犯这么低级的错误。

所以继续去看看:

是否可以换个html-webpack-plugin版本,或许就可以自动依赖的是v2的uglify-js了?

以及去看看,之前正常的时候,html-webpack-plugin是什么版本,以及依赖的uglify-js的版本是多少

此处的配置文件中的是:

“html-webpack-plugin”: “^2.28.0”,

然后本地npm install后的是:2.30.1

然后再去贴上html-webpack-plugin完整的依赖:

│ ├── [email protected] deduped
│ ├─┬ [email protected]
│ │ ├─┬ [email protected]
│ │ │ ├─┬ [email protected]
。。。
│ │ └── [email protected]
│ └── [email protected]

所以是:

[email protected] 

-》[email protected]

-》[email protected]

所以,先试试,把package.json中的html-webpack-plugin的版本指定为2.28.0

看看效果如何

去package.json中的

devDependencies

加上:

试试

npm install

然后再去试试 npm run build

问题依旧。

The repo provided is using an old version of uglifyjs-webpack-plugin that uses uglify-js which is ES5 only:
[email protected] uses the ES6+ capable uglify-es module.
The repo’s [email protected] prod config is also pointing an ES5 only uglify-js webpack uglify plugin:

“说的感觉在点子上,但是没有解决办法。

另外某人是去禁止-p参数,不用webpack自带的uglify,用额外的,所以解决了问题

但是此处不想这么做。

去试试,把

HtmlWebpackPlugin

中的:

minify: { collapseWhitespace: true }

改为:

minify : false

希望内部或许没有用到uglify

结果:问题依旧。

然后注意到此处的uglify-js版本稍微低点了:3.0.28

再去试试效果:问题依旧。

npm uninstall uglify-js

然后加上:

“uglify-js” : “3.0.18”,

然后去

npm install

➜  ucowsapp_h5_en git:(master) ✗ npm install
[email protected] /Users/crifan/dev/dev_root/xxx/ucowsapp_h5_en
  ├── [email protected]
  └── [email protected]

然后看看结果:问题依旧。

这就郁闷了:

此处已经保证和之前正常编译的环境中的版本一致了:

[email protected]

[email protected]

[email protected]

但是还是出错。

html-webpack-plugin ERROR in bundle js from UglifyJs Unexpected token: punc ())

html-webpack-plugin from UglifyJs Unexpected token: punc ())

angular – Webpack Error from UglifyJs – Unexpected Token – Stack Overflow

继续排除版本影响

把当前的:

[email protected]

换成:

[email protected]

所以:

先去卸载:

➜  ucowsapp_h5_en git:(master) ✗ npm uninstall webpack
[email protected] node_modules/acorn-dynamic-import
[email protected] node_modules/base64-js
[email protected] node_modules/bn.js
。。。
[email protected] node_modules/webpack

注意到其中有:

[email protected]

再去把:

“webpack”: “^2.4.1”,

换成:

“webpack”: “2.6.1”,

 

再去安装:

➜  ucowsapp_h5_en git:(master) ✗ npm install webpack

然后再去试试,结果:问题依旧。

punc UglifyJs

通过webpack –help,找到:

  –display-error-details     Display details about errors                [布尔]

  –verbose                   Show more details                           [布尔]

加上-v:

“build”: “cross-env NODE_ENV=production webpack -v -p –progress”,

尝试 输出更详细的错误信息,便于准确定位错误的代码和位置

结果不对,就继续运行

所以换为:

“build”: “cross-env NODE_ENV=production webpack –display-error-details -p –progress”,

结果:

没有显示出更详细的错误信息。

“build”: “cross-env NODE_ENV=production webpack –verbose -p –progress”,

结果:

可以显示出更加彩色丰富的信息:

难道是之前搞错了,实际上是:

__offline_serviceworker内部调用了UglifyJs,导致出错的?

doesn’t work with webpack.optimize.UglifyJsPlugin · Issue #37 · iansinnott/react-static-webpack-plugin

UglifyJsPlugin: ES6 Methods Throw Parse Error · Issue #1542 · webpack/webpack

给webpack.config.babel.js中的

use: ‘babel-loader’

改为加上一些参数的,比如:

      {
        test: /\.jsx?$/,
        exclude: /node_modules/,
        // use: ‘babel-loader’
        use: {
          loader: ‘babel-loader’,
          options: {
            “sourceMaps”: true,
            “presets”: [
              [
                “env”,
                {
                  “loose”: true
                }
              ],
              “stage-0”
            ],
            “plugins”: [
              [“transform-decorators-legacy”],
              [“transform-react-jsx”, { “pragma”: “h” }]
            ]
          }
        }
      },

看看效果:问题依旧。

javascript – Uglify SyntaxError: Unexpected token: punc ()) – Stack Overflow

去试试:

➜  ucowsapp_h5_en git:(master) ✗ npm install uglifyjs-webpack-plugin –save-dev
[email protected] /Users/crifan/dev/dev_root/xxx/ucowsapp_h5_en
  ├─┬ [email protected]

  │ ├─┬ [email protected]
  …
  ├─┬ [email protected]
  │ └── [email protected]
  └── [email protected]

然后再去:

webpack.config.babel.js

换上:

import UglifyJSPlugin from ‘uglifyjs-webpack-plugin’;
// new webpack.optimize.UglifyJsPlugin({
new UglifyJSPlugin({

结果:

又出现其他错误:

【已解决】npm run build出错:validateOptions.js throw new _ValidationError2.default(ajv.errors, name)

只不过,还出现了其他一些参数问题,比如:

【已解决】ERROR UglifyJs DefaultsError: `screw_ie8` is not a supported option

但是又出现其他错误:

所以,实在懒得去这么改动了。。。

算了,暂时放弃继续折腾。还是拷贝之前的

node_modules

继续凑合使用吧。

以后有空再继续折腾。
