brew install nginx fails to link

问题:

I am attempting to install nginx using the brew package manager, but it fails to link. How can I fix this?

If you want to host pages on your local machine to the public, you should change that to localhost:80, and run `sudo nginx`. You'll need to turn off any other web servers running port 80, of course.  You can start nginx automatically on login running as your user with:   mkdir -p ~/Library/LaunchAgents   cp /usr/local/Cellar/nginx/1.2.4/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents/   launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist  Though note that if running as your user, the launch agent will fail if you try to use a port below 1024 (such as http's default of 80.)

I had this issue a few days ago with installation of Yeoman. It seems that some of the folders in /usr/local might not be owned by you and that can cause issues. In my case I had a couple of folders in /usr/local/ like that.

Go to /usr/local

cd /usr/local 

Check who owns the folders

ls -l 

Do the following for folders not owned by you (replacing sub-foldername with sub folders name obviously):

sudo chown $(whoami) /usr/local/<sub-foldername> 

and then call

brew link pcre 

It should link successfully.

Hope this helps.

This can sometimes happen if there area already files (or symlinks) with the same name. To force a link, you can use brew link -f pcre. If you want to see whether there are any files preventing the link, you can use brew link --dry-run pcre.

If there are no files listed by brew link --dry-run pcre, then it is likely that jwwishart's answer is the correct one.

I had to remove manually and reinstall pcre and openssl then nginx will work:

brew remove pcre brew remove openssl brew install pcre brew install openssl nginx
