Can't start Glances

[ruipacheco (Rui Pacheco)]

Tried to start Glances and got the following exception:

$ glances
Traceback (most recent call last):
  File "/opt/local/bin/glances", line 5, in <module>
    from pkg_resources import load_entry_point

[ryandesign (Ryan Carsten Schmidt)]

It works fine for me. Why is anything installed by MacPorts using "/Users/ruipacheco/.venvburrito/lib/python/distribute-0.6.49-py2.7.egg/pkg_resources.py"?

[ruipacheco (Rui Pacheco)]

This is a virtualenv I had enabled when I installed Glances. Is Macports using Python from virtualenvs or the system binary?

[g5pw (Aljaž Srebrnič)]

That's maybe because PYTHONPATH is still set up for the virtualenv. Can you try launching glances in a new session?

[ruipacheco (Rui Pacheco)]

$ glances

zsh: command not found: glances

[g5pw (Aljaž Srebrnič)]

well, that is odd. Can you try uninstalling glances and installing it again?

[ruipacheco (Rui Pacheco)]

Activated the same virtualenv and issued the command:

sudo port uninstall glances

which terminated successfully. I then opened a new tab, confirmed no virtualenv was enabled and ran the following command:

sudo port install glances

I then tried to run glances and got pretty much the same error:

$ glances

[g5pw (Aljaž Srebrnič)]

I don't know precisely how virtualenv works, but I know it changes some env variables. Could you post the output of echo $PYTHONPATH and echo $PATH?

[ruipacheco (Rui Pacheco)]

With virtualenv enabled:

$ echo $PYTHONPATH
/Users/ruipacheco/.venvburrito/lib/python2.7/site-packages:/Users/ruipacheco/.venvburrito/lib/python

echo $PATH
/Users/ruipacheco/.virtualenvs/useclark/bin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

without virtualenv

$ echo $PYTHONPATH
/Users/ruipacheco/.venvburrito/lib/python2.7/site-packages:/Users/ruipacheco/.venvburrito/lib/python

echo $PATH
/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

I see that PYTHONPATH is the same for both. I suspect that virtualenv is gumming things up.

[g5pw (Aljaž Srebrnič)]

Yes, that's exactly the issue. Your PYTHONPATH is not being reset. Can you do a export PYTHONPATH="" and then try launching glances again?

[ruipacheco (Rui Pacheco)]

$ export PYTHONPATH=""

[g5pw (Aljaž Srebrnič)]

Ok, maybe I found out what was the issue. Do you have setuptools installed?

You can find that out with port installed py34-setuptools.

[ruipacheco (Rui Pacheco)]

I didn't install it with ports but I'm pretty sure it was installed as a dependency by pip or easy_install.

[g5pw (Aljaž Srebrnič)]

Hmm... But did you install glances using pip? You shouldn't have to call pip or easy_install at all, it should all be done using MacPorts. What's the output of the command port installed py34-setuptools?

[ruipacheco (Rui Pacheco)]

I installed Glances using Macports.

The output is

Ah, so it wasn't installed at all! Did you update Macports recently? Glances should work now.

Should I uninstall and re-install it?

[g5pw (Aljaž Srebrnič)]

It looks like you still have a virtualenv active. That is interfering with glances. Moreover, it looks like your MacPorts tree is outdated. I don't know why it's trying to access a python2.7 module, as it should use python3.4. Please, open a new terminal window and execute:

sudo port -d selfupdate
sudo port upgrade glances

and then run glances again.

[ruipacheco (Rui Pacheco)]

$ sudo port -d selfupdate

[ruipacheco (Rui Pacheco)]

Also, virtualenv is NOT active.

[g5pw (Aljaž Srebrnič)]

This line

"/Users/ruipacheco/.venvburrito/lib/python/distribute-0.6.49-py2.7.egg/pkg_resources.py"

suggests it somehow still uses the virtualenv. Can you try to move/rename the .venvburrito directory temporarily?

Can you post the output of the env | grep -i python command, too?

Will also open a ticket with venvburrito.

[g5pw (Aljaž Srebrnič)]

Can you post the output of the env | grep -i python command, too?

[ruipacheco (Rui Pacheco)]

PYTHONPATH=/Users/ruipacheco/.venvburrito/lib/python2.7/site-packages:/Users/ruipacheco/.venvburrito/lib/python

[g5pw (Aljaž Srebrnič)]

Thank you. What about env | grep LC ?

[ruipacheco (Rui Pacheco)]

LC_CTYPE=UTF-8

[g5pw (Aljaž Srebrnič)]

Ok, that is ​not a valid setting for LC_CTYPE. Do you set that in some config file?

Also, the PYTHONPATH variable was confusing python3.4, so it picked up the modules in .venvburrito instead of the MacPorts modules path.

[ruipacheco (Rui Pacheco)]

I really don't know. Don't think so but can't be sure.

[g5pw (Aljaž Srebrnič)]

Can you try running this

LC_CTYPE="en_US.UTF-8" glances

[ruipacheco (Rui Pacheco)]

$ LC_CTYPE="en_US.UTF-8" glances

[g5pw (Aljaž Srebrnič)]

Ah, you already renamed the directory back. Try this then:

PYTHONPATH="" LC_CTYPE="en_US.UTF-8" glances

[ruipacheco (Rui Pacheco)]

Perfect!

What should I fix?

[g5pw (Aljaž Srebrnič)]

1) You should fix your locale. Find out in your dotfiles where the LC_CTYPE is set.

2) Fix the PYTHONPATH variable. It looks like it's always pointing to the virtual environment. That can't be right, there must be a way to not use it, but I don't know virutalenv-burrito enough to help you, sorry.

[ruipacheco (Rui Pacheco)]

Thank you very much for your help. I believe this issue has been fixed.

I've opened a ticket with the virtualenv-burrito people and lets see where that goes.

[g5pw (Aljaž Srebrnič)]

You're welcome! I also ensured setuptools is always installed with a change in r120639.
