折腾：
【已解决】ReactNative中实现底部Tab页面和顶部导航栏
期间，npm start突然出错：
➜ rn_rse npm start > rn_rse@0.1.0 start /Users/crifan/dev/dev_root/daryun/Projects/xxx/sourcecode/react_native/rn_rse/rn_rse > react-native-scripts start sh: react-native-scripts: command not found npm ERR! file sh npm ERR! code ELIFECYCLE npm ERR! errno ENOENT npm ERR! syscall spawn npm ERR! rn_rse@0.1.0 start: `react-native-scripts start` npm ERR! spawn ENOENT npm ERR! npm ERR!

而刚才还好好的。
难道是安装了：npm install –save react-navigation
就导致此处脚本出错了？？？
难道此处新增加了几个js文件，就不行了？
去搜：
react-native-scripts: command not found
Unable to run playground example · Issue #1708 · react-community/react-navigation
重新去试试：
npm install
➜ rn_rse npm install npm WARN deprecated connect@2.30.2: connect 2.x series is deprecated npm WARN react-native-drawer-layout@1.3.2 requires a peer of react@* but none was installed. npm WARN react-native-drawer-layout@1.3.2 requires a peer of react-native@* but none was installed. npm WARN react-native-drawer-layout-polyfill@1.3.2 requires a peer of react-native@* but none was installed. npm WARN react-native-tab-view@0.0.69 requires a peer of react@* but none was installed. npm WARN react-native-tab-view@0.0.69 requires a peer of react-native@* but none was installed. npm WARN react-navigation@1.0.0-beta.13 requires a peer of react@* but none was installed. npm WARN react-navigation@1.0.0-beta.13 requires a peer of react-native@* but none was installed. npm WARN jest-expo@21.0.2 requires a peer of react-native@* but none was installed. npm WARN react-test-renderer@16.0.0-alpha.12 requires a peer of react@^16.0.0-alpha.12 but none was installed. npm WARN react-redux@5.0.6 requires a peer of react@^0.14.0 || ^15.0.0-0 || ^16.0.0-0 but none was installed. added 579 packages, removed 31 packages and updated 37 packages in 50.741s |
然后安装了500多个包，感觉很诡异啊。。。
结果npm start虽然可以运行，但是最后还是出错：

一堆的error，算了，还是先去解决：
【总结】
最终是：
先去把npm按照提示，换到4.6.1:
sudo npm i -g npm@4.6.1
后，
npm install
npm start
就消除了此问题了。
