Hi hacking/env-setup does not work for me. I’m on a Mac with a previous installation of Ansible via homebrew. The cause is easy to spot, but I’m wondering if there is a specific reason why it is setup in this way. Before running env-setup: which ansible \> /usr/local/bin/ansible echo $PATH \> /Users/magnus/google-cloud-sdk/bin:/usr/local/bin:/usr/local/share/npm/bin/:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/ **usr/local/bin** :/opt/X11/bin I have ansible at the end of my path env variable. Running env-setup: PATH=/Users/magnus/Documents/Programmering/Magnusart/ansible/bin:/Users/magnus/google-cloud-sdk/bin:/usr/local/bin:/usr/local/share/npm/bin/:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin which ansible \> /usr/local/bin/ansible Since the hacking env-setup prefixes the path instead of postfixing the current installation of ansible is still active. Looking in env-setup it prefixes the PATH with the path to the development instance of ansible, is there a particular purpose for this? /Magnus ---

“Since the hacking env-setup prefixes the path instead of postfixing the current installation of ansible is still active.” Doesn’t compute. First path wins in PATH, not the last, so prefixing is entirely correct. [http://en.wikipedia.org/wiki/PATH\_(variable)](http://en.wikipedia.org/wiki/PATH_(variable)) ---

Hi You’re right _blush_. I did figure it was very strange since I also remembered that prefix would win, but I did try it out before posting. Now I see that the issue must be something else since it seems /usr/local/bin/ansible is called both before and after running env-setup (I’m in the same session so I’m very confused). I must be tired, gonna give this a new try. /Magnus ---

The problem is that it does not get set at all. It looks as if it was judging by the output but when echoing $PATH it is not present. I was fooled by the output from the script. When I add the path manually (export PATH=mypath:$PATH) it works. /Magnus ---

You need to source the script not just run it. – Michael ---

Ah! There we go. Thanks.
