BUG描述

error: bundling failed: "Unable to resolve module react-native/Libraries/EventEmitter/EventEmitter

解決辦法

1.先把node_modules目錄下的react-native-root-siblings刪除

2.再把根目錄下package.json里的react-native-root-toast刪除

3.然后重新安裝npm install react-native-root-toast —save

1.進(jìn)入/node_modules/react-native-root-siblings/lib/AppRegistryInjection.js

2.找到import EventEmitter from 'react-native/Libraries/vendor/emitter/EventEmitter’;并修改為import EventEmitter from 'react-native/Libraries/EventEmitter/EventEmitter';

com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.union signatures do not match the previously installed version; ignoring!

解決辦法

這是由于正在安裝的APP與已安裝再手機(jī)上的APP沖突引起的。直接刪除手機(jī)上的APP即可。

SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

解決辦法

項(xiàng)目缺少android環(huán)境變量，從其他原生android項(xiàng)目根目錄下復(fù)制一份local.properties文件到RN項(xiàng)目的android目錄下即可！

解決辦法

根據(jù)問(wèn)題查找得知是在高版本（0.52）以上在metro-bundler引用的路徑錯(cuò)了。將node_modules\react-native-update\local-cli\lib\bundle.js的439行種的metro-bundler改成metro可成功運(yùn)行！[參考文獻(xiàn)

SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

解決辦法

SDK路徑無(wú)效！

1.可以使用Android Studio打開該項(xiàng)目的android項(xiàng)目，Android Studio就會(huì)自動(dòng)校正

2.也可以打開local.properties文件，手動(dòng)修改SDK路徑

解決辦法

已經(jīng)上傳過(guò)同樣版本號(hào)的ipa，重新上傳需要修改版本號(hào)

[問(wèn)題參考]（https://github.com/reactnativecn/react-native-pushy/issues/143）

解決辦法

這是由于react版本引起的，猜測(cè)可能是react版本與引入react-redux兼容性問(wèn)題所導(dǎo)致。

引起B(yǎng)UG的環(huán)境：

"react": "16.0.0-alpha.12",
"react-native": "0.48.1",
"react-navigation": "1.0.0-beta.13",
"react-redux": "^6.0.0",
"redux": "^4.0.1",
"redux-logger": "^3.0.6",
"redux-thunk": "^2.3.0"

消除BUG的環(huán)境：（降低了react-redux版本）

"react": "16.0.0-alpha.12",
"react-native": "0.48.1",
"react-navigation": "1.0.0-beta.13",
"react-redux": "5.0.5",
"redux": "^4.0.1",
"redux-logger": "^3.0.6",
"redux-thunk": "^2.3.0"

BUG描述

執(zhí)行react-native run-android后提示：

leedeMac-mini:RepairUnion lee$ react-native run-android
Scanning 688 folders for symlinks in /Users/lee/RNWorkStation/RepairUnion/node_modules (8ms)
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...
Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html

解決辦法

1.配置全局環(huán)境變量

$ vim ~/.bash_profile
$ export ANDROID_HOME="/Users/[your name]/Library/Android/sdk/android-sdk_r24.2" # 以實(shí)際位置為準(zhǔn)
$ source ~/.bash_profile # 立即生效

2.配置權(quán)限

如果配置環(huán)境后不可以運(yùn)行 可能是無(wú)權(quán)限運(yùn)行,在項(xiàng)目下運(yùn)行 就是為android文件夾下的gradlew命令添加權(quán)限, **在根目錄下執(zhí)行 chmod 755 android/gradlew,本次就是用這個(gè)方法解決 **

3.項(xiàng)目中android目錄下新建文件local.properties,并添加如下內(nèi)容：

sdk.dir=/Users/[your name]/Library/Android/sdk/android-sdk_r24.2

BUG描述

Expected a component class, got [object Object].

解決辦法

BUG描述

com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: Failed to install all

解決辦法

安裝錯(cuò)誤: Gradle 的編譯版本過(guò)高, 不兼容部分5.0+手機(jī), 需要降低版本為 1.3
有兩種解決辦法，一是降低gradle的build版本，改為1.2.3；另一種是升級(jí)你的React－Native至最新版本。
這里提供第一種方法：
1.打開 React Native 的項(xiàng)目, 修改最外層工程的 build.gradle 配置, 降低 gradle 的 build 為1.2.3版本
2.修改Gradle的Wrapper版本，需要修改android／griddle／wrapper／grade-wrapper.properties文件:

classpath 'com.android.tools.build:gradle:1.2.3' // 修改1.2.3

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process ‘command ‘C:\Program Files\Java\jdk1.8.0_77\bin\java.exe” finished with non-zero exit value 2 

解決辦法

1.Builde→rebuild project
2、如果第一步不行的話，那就是因?yàn)閖ar包重復(fù)了，檢查我們的libs文件夾中是否有不使用的jar包，或者
重復(fù)的jar包，delete掉他們。
