Unable to install Opal

[triton62674]

Hi, I'm new to using django and I've run into a problem when installing Opal.

I've used "pip install opal" but I can't use "opal startnewproject" or "opal --version" and the only response I get back is that "opal" isn't an operation or batch file etc.

Any help would be greatly appreciated!

Easy questions first.

If you type "python -V" (capital V) at the command prompt, what do you get? It's possible that your default python isn't the same as the version that pip is assuming...

Hi there,

Sounds like either the pip install step is failing, or it's putting the opal script somewhere that's not on your path....

Could you pastebin the output of the following command?

pip freeze

Probably also worth doing "pip -V" too, and comparing the results...

Sure, https://pastebin.com/1m3nDfXa

Thanks for the prompt reply.

Yup, did so below https://pastebin.com/1m3nDfXa

Hi there,

So a couple of things:

The literal explanation of the error is that although Opal is installed (you can tell from the output of pip freeze) the opal script is not on your %PATH%.

Although you can presumably manage this yourself (I'm not particularly expert working on Windows myself so couldn't tell you) I would suspect that using Virtualenv - a tool for creating isolated python programming environments would manage it for you.

More broadly, Opal is currently known not to work on Windows - we've never had a Windows maintainer and don't do development or deployment there ourselves.

However - we do anticipate changing this very soon!

We're expecting to start work this week to fix the known Windows-only bugs and then set up CI so that we know that tests pass as a minimum.

The work on that will probably be updated in this ticket if you want to stay in the loop.

Until that's fixed, your best bet will be to find a way to work with Opal from a *nix environment.

Hope that helps !

Best

Quick bump to this thread: 

The recent 0.10.0 Opal release (More details: http://openhealthcare.org.uk/blog/2018/04/07/opal-10/) should now support Windows so if you've struggled to install it there please do test it out !
