atom-beautify does not find autopep8 when installed in virtual environment (beautifying Python)

[muppetjones]

I commented on another issue autopep8 Fails when beautifying Python. The symptom is the same, but the error is different, so I opened a new issue.

Thank you in advance!

Error: spawn autopep8 ENOENT
  at exports._errnoException (util.js:734:11)
  at Process.ChildProcess._handle.onexit (child_process.js:1035:32)
  at child_process.js:1127:20
  at process._tickCallback (node.js:357:13)

This error occurs when autopep8 is not installed. However, Atom Beautify can error like this if it cannot find the installation.

1. Can you confirm you have autopep8 installed?
   Run which autopep8 in your Terminal and let me know results

2. What is your PATH environment variable?
   Run echo $PATH in your Terminal.
   Atom Beautify has detected it as: PATH=/opt/local/bin:/opt/local/sbin:/Users/fake_user/local/bin:/usr/local/bin:/Users/fake_user/Dropbox/bin:/Users/fake_user/local/lib:/Users/fake_user/Dropbox/lib:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

1. It is installed, though in a virtual environment. The python autopep8 path is correctly set in atom-beautify, which worked before I upgraded.

[09:49:23 31] $ which autopep8
autopep8 is /Users/biiremployee/venv/default/bin/autopep8

I installed autopep8 in my global python installation (which is on my PATH), and this fixes the error. Did atom-beautify stop using the autopep8 path variable in this version?

2. The path as detected by atom-beautify is correct.

Thank you, Glavin001!

[Glavin001]

I installed autopep8 in my global python installation (which is on my PATH), and this fixes the error.

This makes sense. autopep8 should be in global Python environment.

Did atom-beautify stop using the autopep8 path variable in this version?

Yup, after #282 Atom Beautify attempts to detect the environment variables, such as PATH, and use them. Thus the global Python environment would be used automatically.

---

Looks like the resolution for this is: install autopep8 in the global Python virtual environment. At the moment, since there is not an option to set a autopep8 path in Atom Beautify, there is no workaround.

• I think this is OK behavior, is there any reason why installing autopep8 in global virtual environment would be discouraged? If this is OK, then this issue can be closed.
• I would like to show some helpful messages to help guide users through common problems like this. /cc Gracefully handle errors when beautifier binary is not installed #311

This is fine in most cases. I have started using only virtual environments for a number of reasons--mostly because I recently worked on a server where I did not have root access and needed to install a local version of python3 (the sysadmin did not know what he was doing, and the global python did not work).

I wouldn't expect this to be an issue in most cases because I doubt many people use Atom over a server. The bigger issue would be for programmers who don't have admin rights to their workstation, but the best solution there would probably be for them to find another job (IMHO).

tl;dr: Only when there is limited access to the globlal python, so shouldn't be a big deal.

[Glavin001]

Summary: Officially supported solution for Atom Beautify is to install autopep8 in global Python environment, not in virtual environment.

I have tried to reinstall using pip install autopep8 --force-reinstall. After restarting Atom everything worked.
