在Mac中,参考:

搭建开发环境 – React Native 中文网

去折腾看看。

之前好像其实也折腾过一点react native:

[记录]折腾React Native

但是没继续弄。

现在重新折腾。

➜  pic brew –help
Example usage:
  brew search [TEXT|/REGEX/]
  brew (info|home|options) [FORMULA…]

Homebrew 0.9.9 (git revision aae4; last commit 2016-05-13)
Homebrew/homebrew-core (git revision 949c; last commit 2016-05-13)

homebrew是0.9.9

想要去升级node,但是失败了:

【已解决】Mac中安装React Native期间升级node出错:Error node not installed

➜  ~ npm config set registry https://registry.npm.taobao.org –global
➜  ~ npm config set disturl https://npm.taobao.org/dist –global

【已解决】npm安装yarn react-native-cli时出错:npm ERR Error EACCES permission denied

去看了看Xcode,是已经安装了:

Xcode 8.0(8A218a)的Command Line Tools

结果去安装watchman时,由于之前的安装不干净,导致一堆问题:

【已解决】brew安装watchman时出错:Error Could not link

基于之前对PyCharm的了解,估计是用WebStorm比较好用:

【已解决】Mac中安装WebStorm且破解

然后去运行示例代码:

 

  react_native react-native init AwesomeProject

【已解决】react-native init AwesomeProject太慢

然后去用Xcode打开ios/AwesomeProject.xcodeproj:

去运行:

 

~/dev/dev_root/daryun/KeYouTong/2.0/sourcecode/react_native/AwesomeProject/node_modules/react-native/packager ~

React packager ready.

然后iSimulator中,就可以显示了:

然后去修改文件:

再去Xcode中Cmd+R重新运行,看看效果。

果然是可以了:

【总结】

Mac中安装React Native的主要过程,就是参考官网:

Getting Started (要翻墙,而且速度很坑,经常打开极其慢)

或者参考中文翻译:

搭建开发环境 – React Native 中文网

然后去安装node,homebrew等环境,

最后去:

react-native-cli init 你的项目名

然后再去运行:

iOS的话,直接运行ios目录下的Xcode项目,即可。
