ImportError: cannot import name 'cli' from 'tldr'

[gerazov]

Awesome tool :sunglasses:

I'm getting an import error on a fresh install - am I missing some dependencies?

$ sudo pip3 install tldr

Do you have any other modules installed that might be using the tldr namespace? What's the output from doing pip3 list?

What are the contents of doing cat /usr/bin/tldr?

[gerazov]

I guess it's something with the environment - I can't reproduce on my other machine.

$ cat /usr/bin/tldr 
#!/usr/bin/python
# -*- coding: utf-8 -*-
import re
import sys
from tldr import cli
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(cli())

And the pip3 list

Does /usr/bin/python point at your python3 installation?

[gerazov]

It seems so:

$ which python
/usr/bin/python

$ ll /usr/bin/python              
lrwxrwxrwx 1 root root 7 дек 19 00:53 /usr/bin/python -> python3*

$ ll /usr/bin/python3 
lrwxrwxrwx 1 root root 10 дек 19 00:53 /usr/bin/python3 -> python3.10*

[MasterOdin]

I wonder if the * at the end of the symlink is messing anything up? Does /usr/bin/python --version print out 3.10? And if you do /usr/bin/python, can do you run import tldr at all in the repl?

Really, my only thought at this point on what the error could be is that /usr/bin/python that's referenced in the script above is divorced in some way from where pip3 has installed stuff.

[gerazov]

You're right - it does work in the REPL:

$ /usr/bin/python --version
Python 3.10.1

$ /usr/bin/python
Python 3.10.1 (main, Dec 18 2021, 23:53:45) [GCC 11.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tldr
>>> 

[MasterOdin]

Hm, what is /usr/bin/tldr.py? I think that might be the problem, where /usr/bin/tldr is then looking at /usr/bin/tldr.py to import from, but it's not the tldr that you installed via pip3, and so fails?

[gerazov]

Hmm, seems Python2 code in /usr/bin/tldr.py - removed it and now it works :+1:

Thanks :pray:
