How do I install packages from PyPi into Pythonista on iOS?

your best bet is to install stash, then you can use pip install, for many pure python packages.

Wow, stash is pretty cool.

But — my attempt to use pip fails:

StaSh v0.4.5

In that case, you can manually download and extract the package:

wget https://pypi.python.org/packages/source/c/crypto-enigma/crypto-enigma-0.0.1b3.tar.gz
tar -xzvf crypto-enigma-0.0.1b3.tar.gz
mv crypto-enigma-0.0.1b3/enigma site-packages/enigma
rm -rf crypto-enigma-0.0.1b3

Any idea why it failed. I was hoping to test the installation of my package (using pip) on as many platforms as I could.

Reading the error message might give a clue. (Failed import test)

If it fails on Pythonista with stash, don't worry about it, it's probably because stash's fake distutils/setuptools/pip isn't handling some corner case. Though this error is strange - as far as I know test contains the Python unit test suite (the tests that test Python).

If you want to do some experimenting, you can try to install this patched version of distutils/setuptools and see if your setup.py runs with that.

@Webmaster4o : Actually, I'm not sure what that means. I don't have an import test statement anywhere.

I think "import test" is not a Python command, but a test that pip runs called import. Maybe pip tries to import your module during install as a test? It probably means once it was installed, calling import crypto-enigma failed somehow.

Are all the dependancies installed for your package. Something I noticed is that the Stash version of PiP does not automatically install missing dependancies.

I got it to work by running pip install cachetools before doing pip install crypto-enigma

@Cethric : After installing cache tools I still get:

Is there something else you could have that I'm missing?

For complex packages, you best bet is to look at that line with the http addrss, then use

wget https://pypi.python.org/packages/source/c/crypto-enigma/crypto-enigma-0.0.1b3.tar.gz

then

tar -xzf crypto-enigma-0.0.1b3.tar.gz

Then move the actual package folders into site-packages, which in this case is just the enigma folder.

@JonB : It's a simple package. And in any case I want to be sure it can be installed simply, so it's important to get to the bottom of what about the package is causing this issue.

packages that try to do clever things, like running selftests, or doing machine specific things, usually don't work in stash's simple pip implementation .you may also need to copy pyenigma.py into the enigma or site-packages.

@JonB : That makes sense. It must be the selftest then. (And the limitation about the script I was expecting.) Except — @Cethric said the installation worked for him!

@Cethric are you on the beta? IIRC it changes a few things about the default sys.path, including the fact that "." is included by default. Which sounds like it would be necessary to import the test.py file that is next to the setup.py.

My appologies I got it to work by using pip to instal cache tools and then manually installing py-enigma.

@dgelessus this is not a change in the beta. . is included in sys.path in 1.5. . was accidentally removed in one beta, but was then put back in place in a later beta. Importing modules from the same directory works fine in pythonista 1.5.
