brew package can't link
问题
有时候brew install [package]
之后运行brew doctor
自检会出现not link
错误
~/ brew doctor
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
libevent
运行brew link
发现:
~/ brew link libevent
Linking /usr/local/Cellar/libevent/2.1.8...
Error: Could not symlink include/evdns.h
/usr/local/include is not writable.
这就要求我们改变一些系统文件夹的读写权限,要根据自己文件夹的实际情况去写
sudo chown -R usrname:admin /usr/local/
sudo chown -R usrname:admin /usr/include/
sudo chown -R usrname:admin /Library/...
其中usrname
在系统偏好设置——用户与群组中查找
再运行:
~/ brew link libevent
Linking /usr/local/Cellar/libevent/2.1.8... 817 symlinks created
问题解决。
