android - 在模拟器中运行的 React Native 导致 bundle 失败 : permission denied error

Question

我刚刚用 react-native init 创建了一个项目在 Manjaro Linux 上并用 Android Studio 打开它。然后我跑了react-native start在终端上，然后在现有的模拟器上运行该应用程序，该模拟器打开到红屏，说明:

The development server returned response error code: 500
Metro Bundler has encountered an internal error, please check your terminal error output for more details

在我的终端窗口上，它给了我以下错误:

error: bundling failed: Error: EACCES: permission denied, open '/tmp/metro-cache/52/45f310fea946062ca0c3c6122dec6592f224f34ee755285a39fd0922f1d4c6739388c3'

 BUNDLE  [android, dev] ./index.js ░░░░░░░░░░░░░░░░ 0.0% (0/1), failed.

我查了 /tmp/metro-cache/52文件夹，但没有找到提到的文件。有谁知道可能导致此错误的原因？请注意，当我使用 $ react-native run-android 在我的物理设备上运行它时， 我犯了同样的错误。

Answer 1

我解决了这个问题。

sudo chmod 777 /tmp/metro-cache
cd /tmp/metro-cache
sudo chown -R $USER .

实际上，我不确定哪一个有效。大概chown就够了。
