我刚刚react-native init在 Manjaro Linux 上创建了一个项目，并用 Android Studio 打开了它。然后我react-native start在终端上运行，然后在现有的模拟器上运行应用程序，该模拟器打开到红色屏幕，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.

我检查了/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，当我在我的物理设备上运行它时$ react-native run-android，我得到了同样的错误。

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。
