After pip install, 'haros init' fails with 'ImportError: no module named haros' #101

Closed evpitts closed 3 years ago

evpitts commented 4 years ago

I ran pip install haros on Ubuntu 16.04, which gave me

ERROR: Cannot uninstall 'enum34'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

So I tried again with the --ignore-installed flag and it ran without error. However, when I try a 'haros init', it fails with Traceback (most recent call last): File "/home/droge-robotics/.local/bin/haros", line 7, in <module> from haros.haros import main ImportError: No module named 'haros'

Seems like a problem in the Python environment, and not with Haros itself @evpitts.

Is this a virtualenv or system install? Python 2.7 or 3.x?

git-afsantos commented 4 years ago

I just tried a fresh install in a new virtual environment and everything worked without an issue.

$ virtualenv issue
$ cd issue/
$ source bin/activate
$ pip install haros
$ haros init

No errors found, got the expected output. This was on Ubuntu 18.04, not 16.04, but I doubt that is the root of the problem.

evpitts commented 4 years ago

I tried it in both the system install and a virtual environment. This is 2.7

git-afsantos commented 4 years ago

It works under Python 2.7, so that is not the issue.

As I said, I have tested it multiple times with fresh virtual machines, and never ran into an issue. Something is different about your setup or environment. Without further details (commands used to install, etc.), I am afraid I cannot help much.

Have you tried the steps I listed in the previous comment?

evpitts commented 4 years ago

I have tried those steps. I'm still getting the same error. What further details would be helpful?

git-afsantos commented 4 years ago

At this point I can only google around, same as you can.

I see that there are other projects where people ran into similar errors, and the solution seems to be reinstalling the faulty package (enum34 in your case) via pip, instead of apt-get.

Do it at your own risk. Here are some links that may be helpful.
