问题
preface: new to OSX development.
cabal install snap --this works fine.
When I type snap into the terminal nothing happens. How do I export my snap path to my $PATH in OSX?
same thing happens with happstack and yesod.... those are both installed as well
回答1:
Simply do (in the terminal):
export PATH="$HOME/.cabal/bin:$PATH"
To make it permanent, add that line to the hidden .profile file in your home directory and re-login. You can edit ~/.profile using open ~/.profile. This can also be done with this line in the terminal:
echo 'export PATH="$HOME/.cabal/bin:$PATH"' >> ~/.profile
