Request help w/pip install jq

[Ed Walser]

Hi all,

I've tried installing jq several times in my local environment, but it
fails, saying it can't find a file that pip downloads. Here is the entire
pip output:

(base) C:\Users\edwal>pip install jq

I notice a mention of Anaconda in the traceback. Are you using Anaconda
instead of the standard Python from python.org?

If so, try using "conda" instead of "pip".

Don't install that way, do:

python -m pip install jq

or, since you seem to be on Windows, if you use the Python Launcher, do:

py -m pip install jq

That won't help your problem, though. Which is:

pip tries to install a wheel first, if it didn't find a suitable one, it
gets the source package (generally called an sdist) and tried to build
it. This usually fails on Windows, because Windows doesn't come with
compilers by default, and even if installed, often goes awry anyway
because the setups never seem to match. If people want you to build for
Windows yourself, there will usually be a detailed description of how to
get it set up the right way.

That's the general story.

Now the bad news:

https://pypi.org/project/jq/#files

there are in fact no wheels for Windows here.

And on the main page

https://pypi.org/project/jq/

there is no mention of Windows at all, so the guess would be it's not
supported.

You might search if someone has gotten this working / packaged it for
Anaconda, since you seem to be using that. If so, you'll want to
install it with the conda command, not pip. See suitable instructions
within the Anaconda website.

choco is a fine and useful tool, I use it lots.

but I think what's there is the base jq package, not the Python bindings
which would presumably the topic of interest in a Python mailing list.
