Installing new modules with distutils fails

Proxy

Hello everyone

I'm working on another pip module for Pythonista. It's all done. Searching, downloanding, unziping. But the last step fails. I can't get to work setup() function.

ImportError: No module named _osx_support

Google tells nothing wise. Any ideas?

briarfox

Anyone ever figure this out?

JadedTuna

@briarfox, I am not sure if this is possible. I think _osx_support is a builtin module in Python on Mac. I will do some research, if I have free time :)

You can try manually copying folder with python scripts to ~/Documents/site-packages

briarfox

@ShadowSlayer Thanks, Yeah I've always just copied over to site-packages but I'd like to learn to use distutils and how to properly setup packages. If you find anything please share!

@ShadowSlayer I loaded osx_support.py to see what happens. Looks like distutils cant get the correct platform.

I had this issue last night while trying to get Jinja2 working with Pythonista. I succeeded by stubbing out the function in dist tools and getting it to drop out to the default platform.

So I got Jinja2, unidecode, slugify and nvd3 working.

Moe

@Kenbo01 How did you that/What exactly did you do? I would like to hack it working as well.

TheWizza

@Kenbo01 Way to leave us hangin'... It's all good, I'll check back in another year-and-a-half.

ccc

Jinja2 v2.7 is bundled into Pythonista v1.6 beta.

wradcliffe

I was waiting to see what @Kenbo01 was doing with Jinja2, unidecode, slugify and nvd3 in Pythonista. Probably just a another very complicated pie chart generator that could be written in 10 lines of simple Python.

TheWizza

I've kinda got the feeling we won't be hearing from @Kenbo01 anytime soon. If anyone would like to try help us noobians figure out the stub out process, you can find stubout.py at https://code.google.com/p/pymox/source/browse/trunk/stubout.py?r=49. I've been running into the same error message as @Proxy when trying to run larger modules' setup files. Thus far, I've been able to avoid this whole process with smaller modules such as pyperclip by moving them to the site packages directory, but it seems like the whole setup process is unavoidable when trying to access larger modules such as muntjac and Kivy. Any help on is subject would be greatly appreciated!

JonB

Guys, just use stash. The pip module of stash is reasonably good, considering the limitations of this platform. This at least automates the process of copying files into site-packages.

JonB

By the way:
it should be reiterated: modules that require cython cannot be installed in pythonista. So Kivy is out.

As for muntjac, see http://omz-forums.appspot.com/pythonista/post/4519765884272640

TheWizza

@Jon B, thanks for all the help. Trust me, I would love to use StaSh, but unfortunately I'm not too familiar with shell languages. I'm pretty much coming from a self-taught web developer background, and Python is actually the first official high-level language I've tried to pick up outside of HTML/CSS/JavaScript. In fact, this is day two of my Python journey. Not having much luck either. I can't even figure out how to run scripts from the Pythonista command line lol. It may take a few days, but I'm sure I'll get it figured out!

JonB

The pythonista commandline isn't really for running scripts.
(if you use stash, you can run scripts from the commandline).

You can run scripts from the editor, by pressing play.
Or, add to the action menu.

TheWizza

@Jon B, yeah that's what I kinda figured. I was able to run across @briarfox's python_run.py which is exactly what I needed. I appreciate all the help.

For anyone in the future who may be running into similar issues, this method has worked for me:
<pre>

Search for and download modules using pipista:
- import pipista from the console (make sure it is located in the 'site packages' dir)
- Search for modules using pipista.pypi_search('module_name’)
- Download modules using pipista.pypi_download('module_name')
  
  pipista.py info - http://omz-forums.appspot.com/pythonista/post/6400412475195392
Unzip/untar with StaSh:
- Locate directory of zip file (default location is ~\Documents)
  - Change directories with the following commands:
  - cd directory_name
    - examples (don't type the $ symbol):
    - $ cd \downloads
    - $ cd "\Zip Files" (for directory names with two words separated by a space)
  - Go back one directory:
    - $ cd ..
  - Go back to parent directory:
    - $ cd
- Extract files with the following commands:
  - .zip files:
    - $ unzip module_name.zip
  - .gz files:
    - $ ungzip module_name.gz
  - .tar files:
    - $ untar module_name.tar
```
StaSh - https://omz-forums.appspot.com/pythonista/post/5894157600030720
```
Read the tutorial linked below to learn how to install via StaSh:
- Tutorial - http://omz-software.com/pythonista/docs/ios/bottle/tutorial.html
- The actual command for installing the module will look like this:
  - $ pip install module_name
Done.
</pre>

Hope this helps. If anyone has a better method, please feel free to comment below. It literally took me two days to figure that shit out. Hopefully this will save somebody some time in the future.

Holla from the past.

@TheWizza, these manual steps are unnecessary.

Using stash,

pip install module_name

is all you need. Pip does the searching, downloading and unzipping for you.

Pip can also search for modules (if you don't know the exact name), update modules, install a specific version, and more. as with any stash command, you can use

pip -h

or

man pip

to learn about pip's capabilities.

TheWizza

@oefe, you are truly amazing, my friend! Big ups to both you and @Jon B!
