react-native run-ios在连接iOS模拟器时出现问题

Question

我在iOS模拟器上运行我的react-native应用程序时遇到问题。它在Android模拟器上的Windows机器上运行正常，所以我很确定它与我自己的代码无关。

这个问题似乎与权限有关。

如果我运行react-native run-ios并将模拟器作为我的用户（不是root用户），它似乎找到了模拟器，但我在构建过程中遇到错误：

Build Preparation

Couldn't create workspace arena folder '/Users/jordan/src/anxiety-work-tracker/ios/build': Unable to write to info file '<DVTFilePath:0x7facd9e06ec0:'/Users/jordan/src/anxiety-work-tracker/ios/build/info.plist'>'.

Couldn't update module cache session file '/Users/jordan/src/anxiety-work-tracker/ios/build/ModuleCache/Session.modulevalidation': You don’t have permission to save the file “Session.modulevalidation” in the folder “ModuleCache”.



** BUILD FAILED **

然后模拟器会加载应用程序，但是有一个错误，说它无法从模块缓存中加载。

如果我以root用户身份运行react-native run-ios而我的用户运行Simluator，则表示无法找到正在运行的模拟设备。

如果我以root用户身份运行，则在运行react-native run-ios时会收到以下内容：

** BUILD SUCCEEDED **


Installing build/Build/Products/Debug-iphonesimulator/AnxietyWorkTracker.app

模拟器不加载任何东西。

更新

根据Rob的评论，我更改了目录上的权限/所有者。

sudo chown -R <username> <srcPath>

这使得构建成功地以非root用户身份运行。无论如何运行react-native run-ios，打开模拟器，在模拟器中打开应用程序，然后产生此错误：

Answer 1

我知道我在对OP的更新中添加了这个，但是我希望将此SO问题标记为已回答，因为它已经过了。

Per Rob的评论，问题是我的源目录的权限。

sudo chown -R <username> ~/src/<project-dir-name>
