==> Caveats 
In the interest of allowing you to run `nginx` without `sudo`, the default 
port is set to localhost:8080. 

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.)

Answer 1

Tuve este problema hace unos días con la instalación de Yeoman. Parece que algunas de las carpetas en/usr/local pueden no ser suyas y eso puede causar problemas. En mi caso, tenía un par de carpetas en/usr/local/así.

Ir a/usr/local

cd /usr/local 

Comprobar que posee las carpetas

ls -l 

hacer lo siguiente para las carpetas que no pertenecen a usted (en sustitución de sub-foldername con subcarpetas nombrar obviamente):

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

y luego llamar

brew link pcre 

Debe vincular correctamente.

Espero que esto ayude.

Esto a veces puede suceder si ya hay archivos (o enlaces simbólicos) con el mismo nombre. Para forzar un enlace, puede usar brew link -f pcre. Si desea ver si hay algún archivo que impida el enlace, puede usar brew link --dry-run pcre.

Si no hay archivos enumerados por brew link --dry-run pcre, entonces es probable que la respuesta de jwwishart sea la correcta.

tuve que quitar y volver a instalar manualmente pcre y openssl continuación nginx funcionará:

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