在运行 React Native 初始项目时，出现了 watchman.plist 权限被拒绝的问题。

Question

我开始使用react-native，按照网站上的教程操作，但是在运行示例项目时，终端返回了一些错误信息：

我试图修改 com.github.facebook.watchman.plist 的文件权限，但实际上那里没有这个文件。也许我应该更改文件的路径?

我尝试过以下方法：

1. brew update
2. brew upgrade watchman
3. brew uninstall watchman && brew install --HEAD watchman
4. 重新启动并重新初始化项目

软件包版本（如果需要）:

1. node: v5.2.0
2. watchman: v4.2.0

Answer 1

当前用户没有对文件夹/Users/[用户名]/Library/LaunchAgents的权限。

使用以下命令来修复此问题：

$ sudo chown $(whoami) /Users/$(whoami)/Library/LaunchAgents

Answer 2

请确保/Users/username/Library和/Users/username/Library/LaunchAgents的所有者是username并且具有正确的权限；以下是我的设置：

$ 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

请确保您不要以root或通过sudo运行watchman。

问题已解决，谢谢！我没有意识到在第一次运行watchman时会创建plist文件，而“~/Library/LaunchAgent”仍然归根所有。 - Kent Yang

我的情况不同。我该如何解决？$ ls -ld ~/Library/LaunchAgentslrwxr-xr-x 1 muhaimincs staff 46 Aug 16 11:03 /Users/muhaimincs/Library/LaunchAgents -> /usr/local/opt/mysql/homebrew.mxcl.mysql.plist - Muhaimin

这是我所错过的~/Library/LaunchAgents/com.github.facebook.watchman.plist。您可以在此处查看我的问题http://stackoverflow.com/questions/34912523/error-watchman-no-pretty-get-sockname-when-run-npm-start。 - Muhaimin

运行以下命令：$sudo chown <username> ~/Library/LaunchAgents - Jashan PJ
