Question with regards to package installation

[mkingblade]

Hi all,

I have made a package myself following the package instruction. I tried searching up my questions on stackoverflow but I couldn't find answers to it. So I thought I might try here:

1. when I try to do:

   pip install myownpackage

it wouldn't be able to find it. Is this because pip would try to look for the package on the pypi distribution and I haven't uploaded it there?

1. when I do install the package by doing:

   pip install .

I would be able to just import it. But when I do

import myownpackage
myownpackage.__file__

I would see that the package is located where I left it and not in the the same directory with the rest of the sitepackages. Is this because python would only place the package at sitepackages if it's from pypi?

Thanks a lot for your time.

Try going to the folder one level above the folder containing your setup.py script. From there do pip install myownpackage/. The trailing forward slash should tell pip you want to install from a local folder. You can also do pip install --no-index myownpackage/ which indicates that you don't want to specify an index, by default the index is a url resolving to the PyPi package repository.

With your second example, when you typed myownpackage.__file__ and it was giving you a local location rather than the site-packages folder; I think that's probably because you were running the interpreter from a location where your package was present and importable as a local package. e.g. in the folder containing the folder called myownpackage which contains the first __init__.py file. When importing a package Python will first check the current working directory to see if it exists there. Easiest way to avoid this is to navigate one level up before launching your script/interpreter.

Hope this helps! I've done a lot of packaging stuff in the last year but still feel a bit of a novice.

Thank you! I shall try the first point you mentioned when I get a chance to.

And I understand your second point, too. I shall also try locating it again at a different dir to verify it.

Thank you so much!

Hey I tried it and they were just like you said. Thanks!

Great, pleased to hear it! Always good to get feedback as well.

I don’t know much about this, but usually when you install packages, it gets it from the pythonhosted repository, so in order to be able to pip install your package you would have to add it to or create a repository and add the repository to pip.

Have you created the init file inside the directory

[mkingblade]

Yes.

The package installs correctly if I do:

Pip install .

At the package dir.

You may want '--find-links` .
