编译时的坑

SignIn时遇到的link相关的bug

解决方案：Unable to use signIn - Cannot read property 'computeModPow' of undefined #563

npm install
react-native link amazon-cognito-identity-js　　<----　手动加上即可！
react-native run-android

 

cannot override getUseDeveloperSupport() as protected

 

 

undefined is not an object(ecaluating 'ReactInternals.ReactCurrentOwner')

 

 

npm install 遇到的问题

(1) git 权限问题

jeff@un-UX303UB$ sudo npm install
npm ERR! code 1
npm ERR! Command failed: /usr/bin/git clone -q git://github.com/react-navigation/react-native-tab-view.git /home/jeff/.npm/_cacache/tmp/git-clone-e519b87d
npm ERR! /home/jeff/.npm/_cacache/tmp/git-clone-e519b87d/.git: Permission denied
npm ERR! 

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/jeff/.npm/_logs/2018-11-03T01_46_05_628Z-debug.log

解决方案：https://docs.npmjs.com/getting-started/fixing-npm-permissions

先尝试使用npm 而不是直接sudo。

参考：https://github.com/KraigM/homebridge-harmonyhub/issues/97

 

(2) brew.sh的exec问题

Library/brew.sh: line 177: exec: : not found

解决方案：https://github.com/Linuxbrew/legacy-linuxbrew/issues/1077

安装brew的正确姿势：Install Homebrew In Ubuntu 16.04

 

(3) curl: command not found

sudo apt-get install curl 

之后才能：

brew install node

 

编译 signed apk 卡住了

Ref: android studio 一直卡在Gradle:Build Running的解决办法

运行时的坑

React Native version mismatch

Ref: https://github.com/expo/expo/issues/923

检查package.json中的react native版本号是否一致。
