Screenshots

After typing the command to get logs i'm getting that. I guess the issue come from the unreachable "localhost".

Your virtualenv is not set up correctly if gunicorn doesn't exist. Try installing again.

[kizniche]

Just run sudo ~/Mycodo/install/setup.sh

[juleszimmermann]

I just tried, same as before, it's trying to connect to localhost but it fails

[kizniche]

What are the errors in the setup log?

[kizniche]

~/Mycodo/install/setup.log
Please don't paste the entire log here, attach it.

It appears to be an issue installing the virtualenv package:

[juleszimmermann]

yep ! i'm trying to reinstall it, it seems that some package are unreachable, so i installed it manually from the github repo

[juleszimmermann]

basic install with "sudo pip3 install virtualenv" failed, i'm not sure if it comes from my side or not

See if this works:

~/Mycodo/env/bin/pip install --upgrade setuptools
~/Mycodo/env/bin/pip install virtualenv

That doesn't appear to be the output of the two commands I provided, as it has the attempted execution of "/home/pi/Mycodo/mycodo/scripts/upgrade_commands.sh" in the middle.

Can you copy the output from the two commands?

[kizniche]

virtualenv 20.7.1 was released 12 hours ago, and I don't see any issues on its github since it's such a new issue. It appears to be some issue with that package, not pip or Mycodo. You can attempt to install the previous version rather than the latest by doing the following:

Change this line:

Mycodo/mycodo/scripts/upgrade_commands.sh

Line 198 in 8fab275

pip install virtualenv --upgrade

to this:

            pip install virtualenv==20.7.0

Save, then run setup.sh.

I was experiencing the same issue, and updating to install virtualenv=20.7.0 worked for me, seems to be up and running now. Thanks!

[juleszimmermann]

Installing virtualenv=20.7.0 works for me too, it works perfectly now , thanks !
