Installation Error COMPAS with PIP

getting started
1

Hi,
when I tried to install COMPAS with pip (pip install COMPAS) I got always the same error message (see below) and the Installation stoped at this point.
What can I do, to overcome this issue?

Thx for help :slight_smile:

It is recommended to install compas using Anaconda instead of pip. Especially on Windows, because installing all required dependencies is very hard otherwise.

can you let us know if installing through conda solved the problem?
thanks…

I think COMPAS is now installed (see screenshot)

Sry for taking so long to answer… I had have many installation errors with using anaconda 3.7 (for python 3.7).
I’ve now installed COMPAS by using Aanaconda 2.7 (for python 2.7) and it finally works!
But importing the module compas (compas_rhino, etc.) just works through specific Anaconda Prompt…Unfortunatly importing the compas modules is still not working in the default Command Prompt !

Is this a problem? Or do you think that everything would work fine now?

Thank you for you’re support!

hi,

that is indeed not a problem (recent versions of Anaconda no longer register their default Python on the PATH). if you want to use use Python/COMPAS from the command line, use the Anaconda Prompt.

in an editor or in Rhino/Blender this will not be a problem in any case. see https://compas-dev.github.io/main/environments.html for more info.

note that we recently updated the version specifications of the dependencies of COMPAS and that some of the installation problems might be resolved since version 0.5. also, you don’t have to install Anaconda 2 to use Python 2.7. you can just create a new environment and specify the version of Python you wish to use…

and finally, if you encountered undocumented installation issues, please let us know, so we can fix them!

best,
tom
