Install also dependencies when installing a package

[jankaWIS]

Hii @mwshinn, I have just been installing your package (on Win) and got into missing dependencies (paranoid). I have noticed then that you're also responsible for that package. Would it be possible to install those (and possibly other) dependencies along the way as it is done eg when one uses conda or pip? Just to make it more user friendly. Besides that one just fyi I was also missing fitz which I have not seen in the list of dependencies (I guess it's under PyMuPDF but it's not that obvious).

[mwshinn]

It should already happen if you do "python setup.py install" to install it. Do you get different behavior?

[jankaWIS]

That is how I have done it before writing the comment. I have not tested it since (if you mean that), I can try to do it again.

I used python setup.py install to install, but I got errors on install and had to install paranoid and PyMuPDF manually before python setup.py install would run error-free.

[mwshinn]

I think the latest push should fix the problem. Essentially, CanD installation accidentally depended on these packages. Let me know if you are still getting errors.

EDIT: I resolved this by doing python3.7 -m pip install PyMuPDF separately, and then rerunning python3.7 setup.py install and it worked and the rest of the dependencies installed. I'm not sure why PyMuPDF wouldn't install without this separate command, but will leave this comment here in case it happens to anyone else.

I just tried in a clean venv (on a linux system where I don't have full privileges and can't use conda). I get the following error, which is likely not related to CanD but I'm not totally sure. I did not have this issue previously when I manually installed the missing packages, but in this venv I can't seem to get it to work:

Looks like there is still something going on here. I will open this issue back up and take a closer look.

[mwshinn]

Could you please run the following three commands on the terminal of the computer which had this issue and post the output?

cat /etc/issue

uname -a

python3 -c "import setuptools; print(setuptools.__version__)"

Thanks!

I can reproduce this in a VM using your version of setuptools if mupdf is not installed. For some reason, old versions seem to require mupdf (which pymupdf depends on) to be recompiled, rather than using the distributed binary. If you upgrade setuptools to the latest version (or at least major version 43), it should install normally.

Ah sounds good -- I'm not going to test to verify that now because my installation is working for me, but thank you for figuring it out!
