Missing 'requests' module

[ghost]

This problem might be with my python installation, but python seems to break so easily that, even if the problem is with my installation, others might have the same problem.

The problem is as follows.

~ $ ddgr test
Traceback (most recent call last):
  File "/usr/bin/ddgr", line 25, in <module>
    import requests
ImportError: No module named 'requests'

sudo -H pip install requests worked but did not prevent the above error message.
Linux Mint Cinnamon 18.3 x64

EDIT: here are some relevant details of my system.

~ $ which python
/usr/bin/python
~ $ python
Python 2.7.12 (default, Nov 20 2017, 18:23:56) 
[GCC 5.4.0 20160609] on linux2

Also: compiling from the git source did not solve the problem.

FURTHER EDIT:

$ python3 ddgr test
Traceback (most recent call last):
  File "ddgr", line 25, in <module>
    import requests
ImportError: No module named 'requests'

pip might be defaulting to python2. Try using pip3.

I have the same problem. It can't find requests despite being installed for python3. Running on a Gentoo.

-> % pip3 install --user requests
Requirement already satisfied: requests in /usr/lib64/python3.5/site-packages
Requirement already satisfied: chardet<3.1.0,>=3.0.2 in /usr/lib64/python3.5/site-packages (from requests)
Requirement already satisfied: idna<2.6,>=2.5 in /usr/lib64/python3.5/site-packages (from requests)

What if you purge the existing one and run:

sudo pip3 install requests

?

[tsurai]

That is not possible on gentoo because it might break important system tools. I either use the --user flag or install the dev-python/requets package via emerge.
Both methods do not seem to work. Unfortuanitly I don't develop with python myself so I can't say what the correct way to handle Gentoos usecase is.

[jarun]

Unfortunately, I don't use Gentoo myself. But I don't see how it's a problem with ddgr. You'll probably get the same error just with:

#!/usr/bin/env python3

import requests

[tsurai]

Ok, I found out why it didn't work for me. pip installed requests for python3.5 but ddgr was run with python3.4... soo yea, enduser error by me... sorry
Maybe @CottonEaster has the same problem.

Can you advise on how to implement your solution?

[jarun]

He is saying you should run it as:

python3.5 ddgr something
or
python3.4 ddgr something

and try to figure out the correct python version for which pip3 installed requests module.

I am closing the bug as it's not a ddgr issue.

[jarun]

If you still face issues raise a defect on the requests/pip module to understand the installation better in your environment.

[ghost]

Thanks people. I'm afraid I've just uninstalled ddgr, because I couldn't get it work.

Have you, developer, considered making a 'flatpack' doogit of ddgr? It might save hassle.

[jarun]

What's the output of the following commands:

~$ which python3
~$ ls -l /usr/bin/python*

For me, for example:

~$ which python3
/usr/bin/python3
~$ ll /usr/bin/python*
lrwxrwxrwx 1 root root       9 May 14  2016 /usr/bin/python -> python2.7*
lrwxrwxrwx 1 root root       9 May 14  2016 /usr/bin/python2 -> python2.7*
-rwxr-xr-x 1 root root 3542008 Nov 23 22:38 /usr/bin/python2.7*
lrwxrwxrwx 1 root root       9 Aug 13 01:26 /usr/bin/python3 -> python3.5*
-rwxr-xr-x 2 root root 4464400 Nov 28 22:23 /usr/bin/python3.5*
-rwxr-xr-x 1 root root     329 Jan 19  2016 /usr/bin/python3.5-coverage*
-rwxr-xr-x 2 root root 4464400 Nov 28 22:23 /usr/bin/python3.5m*
-rwxr-xr-x 1 root root     324 Jan 19  2016 /usr/bin/python3-coverage*
lrwxrwxrwx 1 root root      10 May 14  2016 /usr/bin/python3m -> python3.5m*
~$

This way you would know the python versions installed for you. Also, as we can see from the first line, in my case, the symlink python links to python2.7 for me.

Now you can try to run using specific versions, for example:

$ python2.7 ddgr hello // 2.7 not supported, just for example
or
$ python3.5 ddgr hello

Also, I did face issues with requests dep in another utility of mine. I am considering getting rid of it using the relatively low-level urllib3 library.

[jarun]

I guess the problem remains the same with urllib3 as it is also an external library. But using urllib or urllib2 will be reducing capabilities we may use later.

So, I guess that's the best I can offer. If you are facing dependency issues on your distro you'll have to figure them out. And there are issues like this too! I can suggest:

• remove old versions of requests

• re-install

  pip3 install --upgrade pip3
  pip3 install --upgrade requests
  

• try manual hit and trial using the correct version of python, say, python34, python35...

• if any of those work, create an alias to ddgr

  alias ddgr='python34 ddgr'
  

[jarun]

@CottonEaster dependency on requests, urllib3 are gone for good in release v1.2. I believe you won't face any further issues with installation.

[ghost]

It works! However, there is a small problem. I'll file it separately. EDIT: so you can close this thread.
