大佬教程收集整理的这篇文章主要介绍了node.js – 在运行react-native初始项目时,watchman.plist权限被拒绝大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
我开始使用react-native,我按照网站上的教程,但在运行示例项目时,它在终端上返回了一些错误消息:

Looking for JS files in

我试着chmod com.github.facebook.watchman.plist,但实际上那里没有这样的文件.也许我应该改文件的路径?

我试过的其他事情:

> brew更新
> brew升级守望者
> brew uninstall watchman&& brew安装 – HEAD守望者
>重新启动并重新启动项目

包版本(如果需要):

> node:v5.2.0
>守望者:v4.2.0

解决方法

确保/ Users / username / Library和/ Users / username / Library / LaunchAgents归用户名所有并拥有正确的权限;这是我的看法:

$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

还要确保不以root用户身份或通过sudo运行watchman.
