为什么“npm doctor”会产生权限错误？

Question

当我运行时，npm doctor我收到了以前从未见过的权限错误：

Perms check on local bin folder     not ok  Check the permissions of files in /Users/Orome/node_modules/.bin
Perms check on global bin folder    not ok  Check the permissions of files in /usr/local/bin

我没有做任何我知道会导致此更改的更改。

是什么导致了这种情况，我该怎么办？

Answer 1

对全局 bin 文件夹进行权限检查： npm doctor 在 /usr/local/bin/.keepme 文件上缺少可执行文件

这解决了我的问题：

chmod +x /usr/local/bin/.keepme

对本地 bin 文件夹进行权限检查： 命令执行位置缺少 node_modules/.bin 文件夹，您可以手动创建它或使用命令：

mkdir node_modules && cd node_modules && mkdir .bin

Answer 2

看来 Homebrew 和节点可能会不同步并因此产生此错误。无论如何简单地

npm install -g npm

可能会照顾它。

如果失败，请确认其.keepme为空并尝试

rm -rf /usr/local/bin/.keepme
