Locust: Successfully installed but locust command not found on macOS Sierra 10.12

[Fiona0205]

Hi,

I use python version 2.7.10 on OSX 10.12.

I first installed the locustio using the command "pip install locustio" then I got an error of " error: could not create '/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/greenlet': Operation not permitted"

Then I tried to use command "pip install --user locustio", it says lucustio installed successfully!

However, when I type locust I get an error of "command not found"?

Please does someone know what is going on?

Thank you!

pip --version
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)

virtualenv --version

Hi!

Have you created, and activated, a virtualenv when you're doing this?

I think one could get that error if Locust were installed system globally while the system global python bin path wasn't on the $PATH environment variable.

[Fiona0205]

I first tried to install the Locust on virtualenv and it failed due to the same error "error: could not create '/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/greenlet': Operation not permitted". Then I used command "pip install --user locustio" to install.

After run: $which -a python
I got: /usr/bin/python

echo $PATH
/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Should I add "/usr/bin/python" to my path?

Thank you very much!

[heyman]

I'd recommend installing Locust in a virtualenv. To do this, you need to:

• Create a virtualenv: virtualenv venv (venv is the name, it can be called anything)
• Activate the virtualenv: source venv/bin/activate (now if you run which python it should point within the venv dir)
• Install locust: pip install locustio

See the virtualenv docs for more info.

just for clarity.... the "Operation not permitted" error means you are trying to install locust into your system site-packages without sudo access. You could sudo pip install locustio to get around it and make it available system wide... but the suggestion to use a virtualenv is a better solution.

[Fiona0205]

@heyman I have tried your way, it works! Thanks very much~~

[Fiona0205]

@cgoldberg I have tried "sudo pip install locustio", not work for me. Then I tried "sudo -H pip install locustio", not work either. I don't know why......

[AnastasyaHutasoit]

try this pip install --user locustio

[RogerGan]

ln ~/Library/Python/2.7/bin/locust /usr/local/bin

[jianping-roth]

I had the same problem and I found /Users//Library/Python was owned by root.
Changing the owner solved my problem:

chown -R :staff /Users//Library/Python

combined what @AnastasyaHutasoi and @RogerGan said and it worked. I think it's because the default install of python on a mac needs to be replaced. Guess this could have been done by adding it to your PATH in bashrc or zshrc or wahteverrc

[cgoldberg]

just use a virtualenv

[rainlf]

I use pip install locustio --user to install locust and can't find the command in zsh on my Mac too.
It is a environment PATH problem, I add a command in .zshrc file as blew to fix the problme.

export PATH=$PATH:/Users/rain/Library/Python/2.7/bin

I have the same problem, except I also have the same problem for virtualenv. Should I use virtualenv for virtualenv? ;)

reboot your machine may it will fix in my case it worked.I have python 3.6.9 in my machine
