Locust: Locust Installation error on Ubuntu 16.04 and Debian Stretch

[darkwizard242]

Describe the bug

As far as I understand, Locust package has moved from _locustio_ to locust. I was developing an Ansible role to install locust on a few of Debian family operating systems such as the following:

• Ubuntu 20.04
• Ubuntu 18.04
• Ubuntu 16.04
• Debian Buster
• Debian Stretch

Using python3's pip, locust is successfully installed on Ubuntu 20.04, Ubuntu 18.04 and Debian Buster. However, it attempts to install locustio along with locust and errors out on Ubuntu 16.04 and Debian Stretch.

Expected behavior

Clean installation on Ubuntu 16.04 and Debian Stretch.

Actual behavior

Outputs below error (running locally within a docker container of ubuntu 16.04):

$ python3 -m pip install locust

Steps to reproduce

Install locust on an ubuntu 16.04 or debian stretch docker image.

OR try following:

docker run -it darkwizard242/ansible:ubuntu-16.04 /bin/bash -c 'python3 -m pip install locust' 

docker run -it darkwizard242/ansible:debian-stretch /bin/bash -c 'python3 -m pip install locust' 

Environment

• OS: Ubuntu 16.04 & Debian Stretch
• Python version: 3.5.2 (ubuntu 16.04) and 3.5.3 (debian-stretch)
• Locust version: Default (as failure at installation process with certain operating systems)

[cyberw]

Ignore my previous response... The problem is that you are on Python 3.5. Only 3.6 and up are supported.

[darkwizard242]

@cyberw - Ah, I was thinking the same but thought it would be wiser to confirm it the actual development team (since the behavior of how pip was installing the package was kind of confusing me). Nevertheless, thanks very much. Appreciate that you looked into it for me.

[cyberw]

@heyman Can you delete the locust 0.0 package? I dont have permissions...

Once it is removed people should at least get a more reasonable error message. The reason for the strange error is that locust 0.0 (from 2018) states that it supports 3.5, but it just references locustio. "real" packages released as locust (starting with 1.0) dont support 3.5, so you get the only one that does.

[darkwizard242]

@cyberw - Makes sense. Thanks mate.

[heyman]

It's now removed!

[cyberw]

No problem. If you absolutely need 3.5 support, you can use locustio==0.13.5, but it is getting old at this point :)

[darkwizard242]

@cyberw - Oh cool. I can get by using the higher versions of python3. Thanks again for the help :+1:

[xtrrdnryprgrmmr]

my pip file located in Desktop\PIP file , i try to changed command to python -m pip install locust but it didnt work.

[cyberw]

What happens when you actually run the correct command? (installing locust instead of locustio)

[cyberw]

it is possible (likely even) that you are running into build issues, as there are no prebuilt locust / geventhttpclient wheels for python 3.9 yet.

While you wait, you can try the solutions mentioned at https://stackoverflow.com/questions/61592069/locust-is-not-installing-on-my-windows-10-for-load-testing and see if any of them help

[xtrrdnryprgrmmr]

This solution didnt work for me.

Did you try the fixes mentioned in the stackoverflow post?

[xtrrdnryprgrmmr]

Yes ,i did ; but it didnt work for me

[cyberw]

You tried all three of the suggested fixes, right?

Then I guess you'll have to wait for the next release (which will have pre-built wheels for python 3.9), or switch back to 3.8
