I tried to install the module git-pre-push-hook with:
pip3 install git-pre-push-hook
mkdir test
cd test
git init
touch README.md
install-git-pre-push-hook
But this error is thrown after using the command install-git-pre-push-hook
Any idea why this happens?

I am trying to run python3 with ROS. By default ROS melodic is installed with python2.7.
Hence I have installed the python3 using following instructions:
https://dkqhzm2.tistory.com/entry/ImportError-dynamic-module-does-not-define-module-export-function-PyInitcvbridgeboost-in-Xavier-AGX
where I have cloned the cv_bridge src from the following git: which is called vision_opencv
https://github.com/mikejmills/vision_opencv
I also put in my scripts as
#!/usr/bin/env python3
So that it complies in python3 when I did catkin_make
The following error is the trouble with this package:

Not sure what to do.
If I compile only with python2.7 instead of python3 I get error as:

Can someone tell me how to tackle this problem?
You’re trying to use Python2.x code with Python3, which doesn’t work. If you want to use Python3 with ROS you shouldn’t be using Melodic, since it targets 2.x. You can get it to sort of work with Python3, but it’s still not a great idea.
If you want Python3 you should be using the Noetic distro.
I've always used pip in installing python packages but for some unexplained reason it just stopped working. I have tried the following but still not working
i upgraded pip
i rolled back pip
-i uninstalled my python distribution and reinstalled/upgraded it. Here is a trace back of the kind of error i get whenever i try
installing a package with pip

I am a new developer and learning to code in Python 3.4.2. I am running Debian linux on a Raspberry Pi3. After the fresh install I did both
sudo apt-get update
and
sudo apt-get upgrade
to get everything up to date.
I am trying to test a section of code which uploads a file to Dropbox:
import dropbox
import urllib3
authkey = (my dropbox dev auth key)
with open('test.csv','rb') as f:
dbx = dropbox.Dropbox(authkey)
dbx.files_upload(f.read(), '/test.csv')
Now, I have no idea if the actual Dropbox code is correct, because I am getting the following error when I run the script in the Python shell:
Traceback (most recent call last):
File "/usr/local/lib/python3.4/dist-packages/requests/__init__.py", line 58, in <module>
assert minor >= 21
AssertionError
During handling of the above exception, another exception occurred:

RuntimeError: Requests dependency 'urllib3' must be version >= 1.21.1, < 1.22!
To me this indicates that I have an issue with my urllib3 install, so I go to the bash shell and type:
sudo pip3 install --update urllib3
And get the exact same error message:
Traceback (most recent call last):
File "/usr/local/lib/python3.4/dist-packages/requests/__init__.py", line 58, in <module>

I have other scripts that use Twilio to send SMS messages and they are no longer working either, yielding the same error message referencing urllib3 version issues.
Can anyone help me resolve this issue or point me in the right direction?
Thank you very much.
On Mac try this:
sudo pip install urllib3==1.23
then
sudo pip install requests
This is encountered on Ubuntu 16.04.2, with GCC 5.4.0 and Python 3.5.2. So I built a module and inside the build directory I can easily import it without problem:
➜ build git:(master) ✗ python3 -c "import foo"
➜ build git:(master) ✗
However, when I install the module into install_dir (the module was built with cmake/make and then make install --prefix=$install_dir) and add its location into PYTHONPATH, it doesn't work:
➜ ~ cd
➜ ~ echo $PYTHONPATH
$install_dir/lib/python3.5/site-packages:/usr/local/lib/python3.5/site-packages:
➜ ~ python3 -c "import foo"
Traceback (most recent call last):

Note: naming has been changed to make the case more generous. The funny thing is I ran the same script for 3 different devices with the fresh installed OS, only 1 has this problem (!).
What could be the main cause here that I can investigate further? Or is this something funny caused by Python 3?
Run into this problem today.
The solution for me was:
upgrade petsc (3.7.3->3.7.6) and slepc (3.7.3->3.7.4)
reinstall petsc4py (3.7.0) and slepc4py (3.7.0)
I try to make an easy Python gui, therefore I need to import tkinter. This package is available in Python 3, so I need that interpreter, but I can't get it started in Pycharm. It always asks to install packaging tools and then I get the same error everytime and I can't seem to fix it. I get the following:

I already searched some fixes but none actually worked.
Python PIP might not be installed. In Debian based distribution:
sudo apt-get install python3-pip
should solve if you use Python 3.
For Python 2.7x
sudo apt-get install python-pip
Close PyCharm and re-open it.
In this case, it may be possible that python pip (package installer) is not installed. So try installing that first.:
sudo apt-get install python3-pip
