折腾:

【未解决】把ReactJS-AdminLTE中的导航栏和标题栏集成到react-hot-boilerplate

期间,用:

npm run build

结果出错:

ERROR in ./node_modules/react/lib/ReactComponent.js
Module not found: Error: Can’t resolve ‘fbjs/lib/warning’ in ‘/Users/crifan/dev/dev_root/daryun/Projects/xxxsourcecode/web/AdminManagement/reference/react-hot-boilerplate/react-hot-boilerplate/node_modules/react/lib’

Module not found Error Can’t resolve fbjs/lib/warning

难道是对应的库没有安装?

reactjs – "module not found : Error: Cannot resolve module ‘react/lib/ReactMount’ " – Stack Overflow

Material-ui – cannot resolve module ‘fbjs/lib/emptyFunction’, ‘fbjs/lib/invariant’, ‘fbjs/lib/warning’ – Stack Overflow

去项目中搜了下,发现了:

prop-types

react

react-dom

都依赖于,用到了fbjs

看来是没有安装,去安装试试

➜  react-hot-boilerplate git:(master) ✗ npm install fbjs –save-dev
npm WARN babel-loader@6.2.10 requires a peer of webpack@1 || 2 || ^2.1.0-beta || ^2.2.0-rc but none was installed.
npm WARN react-dom@15.6.1 requires a peer of react@^15.6.1 but none was installed.
added 2 packages in 12.144s

然后同时看看:

fbjs

是个什么库

facebook/fbjs: A collection of utility libraries used by other Facebook JS projects.

“A collection of utility libraries used by other Facebook JS projects.”

unknown module fbjs/lib/invariant · Issue #1026 · aksonov/react-native-router-flux

是个facebook出的库,包含了一堆工具库,用于其他很多facebook的JS的项目的。

难怪此处的facebook出的react,react-dom依赖这个fbjs

安装好之后,可以在:

/react-hot-boilerplate/package.json

  "devDependencies": {
    。。。
    "fbjs": "^0.8.14",

中看到fbjs:

然后再去npm run build就没了该错误了。

【总结】

此处npm run build通过webpack去打包出错:

Module not found: Error: Can’t resolve ‘fbjs/lib/warning’ in

原因是:

缺少了这个fbjs库。

但是之前没有报错的原因是:

此处是刚引入了新的其他代码,内部用到了fbjs这个库。

说明:fbjs是啥:

这个是库是facebook出的,内部包含了一堆工具类,被用于其他很多Facebook的JS项目中。

此处prop-types,react,react-dom都依赖于fbjs这个库。

解决办法是:

安装这个库:

npm install fbjs –save-dev

即可。
