如何解决“无法与您的值班员交谈”错误

Question

几天前我在 Facebook/react-native 上创建了一个问题，但尚未收到回复。为了尝试让我启动并运行，我也会在这里询问。问题链接

我检查了有关此事的其他 SO 帖子，但没有任何建议有帮助。

我正在按照 Mac/iOS 的入门文档来创建 AwesomeProject 示例应用程序。当我使用启动项目时

npx react-native start

并在 Xcode 中构建 iOS 应用程序，应用程序启动（在模拟器中）以显示白色初始屏幕，顶部显示“正在从 Metro 加载...”。大约一分钟后，我收到以下错误：

Could not connect to development server.

Ensure the following:
- Node server is running and available on the same network - run 'npm start' from react-native root
- Node server URL is correctly set in AppDelegate
- WiFi is enabled and connected to the same network as the Node Server

URL: http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=org.reactjs.native.example.AwesomeProject

在我启动服务器的终端中，我看到：

2021-11-13T16:46:53,199: [cli] unable to talk to your watchman on /usr/local/var/run/watchman/chrisluxoft-state/sock! (No such file or directory)

Watchman:  watchman --no-pretty get-sockname returned with exit code=1, signal=null, stderr= 2021-11-13T16:46:53,199: [cli] unable to talk to your watchman on /usr/local/var/run/watchman/chrisluxoft-state/sock! (No such file or directory)

我导航到

/usr/local/var/run/watchman/chrisluxoft-state/

并且目录中没有文件。

我跑了

watchman --foreground --logfile=[pathtodesktop]/log.txt

按照此处的建议，生成以下日志：

2021-11-13T16:49:35,574: [listener] Watchman 2021.11.08.00 <no build info set> starting up on Grey-Mac.local
2021-11-13T16:49:35,581: [listener] file limit is 2560 kern.maxfilesperproc=49152
2021-11-13T16:49:35,581: [listener] raised file limit to 49152
2021-11-13T16:49:35,581: [listener] launchd checkin failed: No such process
2021-11-13T16:49:35,582: [sanitychecks] starting sanityCheckThread

当我回到

/usr/local/var/run/watchman/chrisluxoft-state/

我看到现在有两个文件：pid & sock=

受此鼓舞，我重新启动进程并在 Xcode 中重建应用程序。结果相同，只是这次终端中的错误是：

2021-11-13T16:56:49,310: [cli] unable to talk to your watchman on /usr/local/var/run/watchman/chrisluxoft-state/sock! (Connection refused)

Watchman:  watchman --no-pretty get-sockname returned with exit code=1, signal=null, stderr= 2021-11-13T16:56:49,310: [cli] unable to talk to your watchman on /usr/local/var/run/watchman/chrisluxoft-state/sock! (Connection refused)

再次看着

/usr/local/var/run/watchman/chrisluxoft-state/

我看到相同的两个文件。我期望有一个日志文件，但它不存在。

这是在具有多个用户帐户的 Mac 上，如果有影响的话（即权限）。

node、react-native、watchman 是由 Homebrew 安装的。我使用相同的用户帐户进行安装和执行。
