Ok, I did that and it works:
nano ~/.bash_profile
And paste
export PATH=~/.composer/vendor/bin:$PATH
do source ~/.bash_profile
and enjoy 😉
Important: If you want to know the difference between bash_profile and bashrc please check this link
Note: For Ubuntu 16.04 running laravel 5.1, the path is: ~/.config/composer/vendor/bin
On other platforms: To check where your Composer global directory is, run composer global about
. Add /vendor/bin
to the directory that gets listed after “Changed current directory to …” to get the path you should add to your PATH
.
