折腾：
【已解决】npm start出错：react-native-scripts: command not found
期间，还是先去解决：
➜ rn_rse npm start > rn_rse@0.1.0 start /Users/crifan/dev/dev_root/xxx > react-native-scripts start 17:16:38: Starting packager… ***ERROR STARTING PACKAGER*** Error: You are using npm version 5.0.0. We recommend version 4.6.1. To install it, run ‘npm i -g npm@4.6.1’. ***ERROR STARTING PACKAGER*** |
中的npm的版问题吧。
Error: You are using npm version 5.0.0. We recommend version 4.6.1.
react-native-cli is not compatible with npm@5 · Issue #14767 · facebook/react-native
Hard Error on npm >5 · Issue #275 · react-community/create-react-native-app
算了，还是去安装提示去：
npm i -g npm@4.6.1
结果出错：

去加上sudo试试：
sudo npm i -g npm@4.6.1
➜ rn_rse sudo npm i -g npm@4.6.1 Password: /usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js added 9 packages, removed 146 packages and updated 287 packages in 13.118s |
然后接着去试试：
npm install

一堆的警告，先不去管了。
然后再去：
npm start
就可以正常运行了：
➜ rn_rse npm start > rn_rse@0.1.0 start /Users/crifan/dev/dev_root/xxx > react-native-scripts start 17:29:08: Starting packager… Packager started!
