弹出ExpoKit后，Expo无法正常工作

时间：2020-04-19 15:20:41

标签： android react-native expo

我正在使用Expo应用程序，并且需要将此应用程序弹出ExpoKit，才能使用this library创建p2p聊天。当我设法使用ExpoKit弹出我的应用程序（我从终端的Expo收到“弹出成功消息”，所以我认为还可以）。现在，当我要构建我的项目时，甚至只是品尝一下它是否正在工作（无需更改代码，在使用expo start --lan弹出之前就可以工作）。这是此错误的完整堆栈跟踪。

dolidod@debian:~/PROJECT_DIR/android$ ./gradlew assembleDebug --stacktrace

FAILURE: Build failed with an exception.

* What went wrong:

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:

答案 0 :(得分：0)

检查该库的Android手动安装是否正确。浏览链接，然后再次验证。

Android Installation

此外，您的堆栈跟踪还会在以下几行中提及拒绝权限。检查您是否具有递归应用于项目文件夹中所有目录的写权限。如果没有，则授予该目录的写入和执行权限。

原因：org.gradle.api.UncheckedIOException： java.io.FileNotFoundException： /home/dolidod/KORONAPIVOT/SkateAppFrontend/android/.gradle/4.10.2/fileHashes/fileHashes.lock （权限被拒绝）

由于：java.io.FileNotFoundException： /home/dolidod/KORONAPIVOT/SkateAppFrontend/android/.gradle/4.10.2/fileHashes/fileHashes.lock （权限被拒绝）

要获得权限，请在终端上使用以下命令

chmod -R 777 /project-folder-path

对于您更新的其他错误

转到项目根文件夹，然后尝试以下命令。确保这些操作是在根文件夹而不是android文件夹中完成的。

rm -rf node_modules

npm install -g expo-cli

npm install

expo start or npm start

还要检查是否在AndroidManifest.xml文件中添加了以下权限。

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
