[terminal] sudo: port: command not found

I recently uninstalled Xcode 4.2 and re-installed Xcode 4.3.1. Command Line Tools are installed. I then installed MacPort using “dmg” disk images for Lion from macports.org. Since, I was getting sudo: port: command not found after every use of port, I followed this and this post to create a .bash_profile file(wasn't present earlier) and then put in it the following but to no avail.

export PATH=$PATH:/opt/local/bin
export MANPATH=$MANPATH:/opt/local/share/man
export INFOPATH=$INFOPATH:/opt/local/share/info 

Following this post

?  ~ git:(master) ? rvm install 1.8.7 --with-openssl-dir=/opt/local
You requested building with '/usr/bin/gcc-4.2' but it is not in your path.
?  ~ git:(master) ? vi .rvmrc 

rvm_archflags="-arch x86_64"

export CC="/usr/bin/gcc-4.2"

export CFLAGS="-O2 -arch x86_64"
export LDFLAGS="-L/opt/local/lib"
export CPPFLAGS="-I/opt/local/include"

Renaming .bash_profile to .profile

?  ~ git:(master) ? vi .bash_profile
?  ~ git:(master) ? mv .bash_profile .profile
?  ~ git:(master) ? mv .profile              
usage: mv [-f | -i | -n] [-v] source target
       mv [-f | -i | -n] [-v] source ... directory
?  ~ git:(master) ? mv -f .bash_profile .profile
mv: rename .bash_profile to .profile: No such file or directory
?  ~ git:(master) ? port
zsh: correct 'port' to 'pr' [nyae]? n
zsh: command not found: port
?  ~ git:(master) ? which port
port not found
?  ~ git:(master) ? 

.profile content:

export PATH=$PATH:/opt/local/bin
export MANPATH=$MANPATH:/opt/local/share/man
export INFOPATH=$INFOPATH:/opt/local/share/info

You can quite simply add the line:

source ~/.profile

To the bottom of your shell rc file - if you are using bash then it would be your ~/.bash_profile if you are using zsh it would be your ~/.zshrc

Then open a new Terminal window and type ports -v you should see output that looks like the following:

~ [ port -v                                                                                                              ] 12:12 pm
MacPorts 2.1.3
Entering interactive mode... ("help" for help, "quit" to quit)
[Users/sh] > quit
Goodbye

Hope that helps.

First, you might need to edit your system's PATH

sudo vi /etc/paths

Add 2 following lines:

/opt/local/bin
/opt/local/sbin

Reboot your terminal

If you have just installed macports just run and it should work

source ~/.bash_profile

You could try to source your profile file to update your environment:

$ source ~/.profile

there might be the situation your machine is managed by Puppet or so. Then changing root .profile or .bash_rc file does not work at all. Therefore you could add the following to your .profile file. After that you can use "mydo" instead of "sudo". It works perfectly for me.

function mydo() {
    echo Executing sudo with: "$1" "${@:2}"
    sudo $(which $1) "${@:2}"
}

if you use zsh.please add flowing string to the line 'export PATH="..."' in file '~/.zshrc'

:/opt/local/bin:/opt/local/sbin

What do you get from running which port as your regular user account? Try it from a freshly opened terminal. Try again after renaming .bash_profile to .profile. Can you run port as a regular user, even with no arguments?

On my machine, port is in /opt/local/bin/port - try typing that into a terminal on its own.

I found the answer in the official website

$ vi ~/.profile

# add the following line
export PATH=/opt/local/bin:/opt/local/sbin:$PATH

And now restart the terminal or type source !$ (equivalent to source ~/.profile)
