Unable to launch_stash.py in pythonista 3 for IOS

[siulman]

Hello guys,

I have an ipad pro 10.5 with IOS 11.1 and just downloaded pythonista 3. I want to import some libraries as netmiko with “pip install netmiko”. It appears the best way is with “stash”. So I imported stash with the script:
import requests as r; exec(r.get('http://bit.ly/get-stash').text)

However, when I try to launch “launch_stach.py” from my home directory I get an error on line 28 “from stash import stash” that says “not well-formed (invalid token). Please, check snapshot attached.

If I try to go to “site-packages” —> “stash” and then execute “stash.py” I get an error “No module named “configParser”.

Of course, I tryed to restart pythonista 3 but it didn’t fix the issue.

Could someone please help?

You could try copying the first line of the first script (#!python2) and pasting that in as the first line of the second file and then rerunning the second file. It is my undersstanding that StaSH must run under Python 2 and your error message gives me the impression that you are running under Python 3.

[siulman]

Hello @ccc , thans for your response.

Pythonista 3 is able to run the scripts either with « python 2 » or « python 3 », I tried both with the same result. I tryed to remove « stash » and reinstall it », « force quit » pythonista, etc... but no success.

What do you mean by copying the first line of the first script and pasting on the second one? Could you be more precise on what I need to do please? (What exactly to copy, where exactly to paste...)

I don’t really know what to do...and without pip pythonista 3 is useless for me...

Thanks!

Here below a screenshot with the result of the of Traceback button...maybe it helps...

When running with Python 2.7, the error message is slight different. Here below:

[JonB]

1. What pythonista version are you using? The latest app store version, or the beta?
2. The parse error indicates that your Info.plist is corrupted. You should try removing/reinstalling pythonista. If you have pythonista 2.0 installed, you won't lose any files, otherwise you need to back up first.
3. The ConfigParser error is because you are running stash with python 3.x -- stash is only compatible with python 2.x (which is why launch_stash has the #!python2 at the start.
4. As a workaround, you could also comment out the offending line from shcommon.py, and just set

PYTHONISTA_VERSION='3.1.1'
PYTHONISTA_VERSION_LONG='311016'

(thats from the beta, but it does not really matter as long as the version is > 3.0)

[JonB]

one more thing to look at before reinstalling pythonista:

import sys, os 
print(open(os.path.join(os.path.dirname(sys.executable), 'Info.plist')).readline())

you also never said what device /os versionyou are using -- has ios started switching over to binary Info.plists?

[siulman]

Hi @JonB ,
I appreciate your help and I hope we will find the solution soon as I can’t wait to develop some stuff in Pythonista...

Here is the Info that I thought I already said:

• Ipad 10.5
• IOS 11.1
• Pythonista 3.0 version

I reinstalled Pythonista and then first thing I did is to download “stash”, then I ran “launch_stash.py” with version python 2.7 but still....same error.

I also tryed to run what you asked, here is the output:

I tried to change what you suggested in “shcommon.py” but it didn’t fix anything:

Thank you

@siulman Can you try running this and post the output:

import sys, os 
print(repr(open(os.path.join(os.path.dirname(sys.executable), 'Info.plist'), 'rb').read(256)))

@JonB I have an idea what the issue could be. Pythonista's Info.plist might be a binary plist (rather than XML) in the current App Store version of Pythonista. The Python 2 version of plistlib only supports XML plists I think. The Python 3 version supports both and detects the format automatically.

[JonB]

yeah, binary plist is what i was thinking. (I think it must be an ios 11 thing?)
The solution in 2.7 would then be maybe to use objc rather than plistlib:

if IN_PYTHONISTA:

from objc_util import NSBundle
PYTHONISTA_VERSION=str(NSBundle.mainBundle().objectForInfoDictionaryKey('CFBundleShortVersionString'))
PYTHONISTA_VERSION_LONG=str(NSBundle.mainBundle().objectForInfoDictionaryKey('CFBundleVersion'))


if PYTHONISTA_VERSION < '3.0':
....

[siulman]

Appreciated guys...
@dgelessus here is the output you requested:

@JonB Any workaroung you come up with to make that work?

[dgelessus]

@JonB What exactly does Stash use the Pythonista version number for? If you only need to know whether you're in Pythonista 3 or not, you could probably check sys.executable.endswith("3") instead, or see whether Py3Kit.framework exists or not.

[JonB]

I think it just uses it to report version # at startup, and check for pythonista 3.

The code I posted above should work, in shcommon.py. objc_util is probably overkill, but already imported for stash.

[siulman]

Hello guys,

I modifyed the “shcommon.py” according to the @JonB suggestions and it worked.

I was also able to “pip install netmiko” and connect to my switches to execute the commands I wanted to. I am really happy now! Thanks!

Here below snapshots.

I think this should be taken into account for a new release of the app?

Thank you very much for your help @JonB as long as @dgelessus

[JonB]

if you'd like. you can submit a pull request over on the stash github page. If not, I will do it this week.

I ran into the same problem today. After reading through this thread I realized perhaps it had to do with having both Pythonista 2 and the new Pythonista 3 installed. I uninstalled both and reinstalled 3 and it fixed the problem.
