运行 react-native 初始项目时 watchman.plist 权限被拒绝 [英] watchman.plist permission denied when running a react-native initial project

问题描述

我开始使用 react-native 并按照网站上的教程进行操作，但是在运行示例项目时，它在终端上返回了一些错误消息:

I'm start using react-native and I followed the tutorials on the website, but when running the example project, it returned some error messages on the terminal:

Looking for JS files in

我尝试 chmod com.github.facebook.watchman.plist 但实际上那里没有这样的文件.也许我应该更改文件的路径?

I tried to chmod com.github.facebook.watchman.plist but actually there's no such file there. Maybe I should change the path of the file?

我尝试过的其他事情:

1. 酿造更新
2. 酿造升级守望者
3. brew uninstall watchman &&brew install --HEAD watchman
4. 重启并重新启动项目

软件包版本(如果需要):

Packages Version (if needed):

1. 节点:v5.2.0
2. 守望者:v4.2.0

推荐答案

确保 /Users/username/Library 和 /Users/username/Library/LaunchAgents 是username 拥有并拥有正确的权限；这是我的样子:

Make sure that /Users/username/Library and /Users/username/Library/LaunchAgents are owned by username and have the correct permissions; here's how mine look:

$ ls -ld ~/Library
drwx------+ 57 wez  users  1938 Nov  6 07:49 /Users/wez/Library
$ ls -ld ~/Library/LaunchAgents
drwxr-xr-x  3 wez  users  102 Dec 11 16:13 /Users/wez/Library/LaunchAgents
$ ls -l ~/Library/LaunchAgents/com.github.facebook.watchman.plist
-rw-r--r--  1 wez  users  1545 Dec 11 16:13 /Users/wez/Library/LaunchAgents/com.github.facebook.watchman.plist

还要确保您没有以 root 身份或通过 sudo 运行 watchman.

Also make sure that you don't run watchman as root or via sudo.
