I am trying to use pip on my Redhat system.
I installed pip following the instructions here, but when I try to use it, for example pip install, I get the following error code:
Traceback (most recent call last):
File "/usr/local/bin/pip", line 7, in ?
from pip import main
ImportError: No module named pip
this issue due to common user do not have privilege to access packages py file.
1. root user can run 'pip list'
2. other common user cannot run 'pip list'
[~]$ pip list
Traceback (most recent call last):
File "/usr/bin/pip", line 7, in <module>
from pip._internal import main
ImportError: No module named pip._internal
solution :
root user login and run
chmod -R 755 /usr/lib/python2.7
fix this issue.
If pip is already installed and your unable to access it, one of the reason could be that you don't have permissions to read or execute the library. Try doing
sudo chmod -R u+rx /usr/lib/python2.7/site-packages/pip/
If pip is installed in a different folder, you can obtain the folder path by doing
>>> import pip
>>> pip.__path__
['/usr/lib/python2.7/site-packages/pip']
If you don't have root rights and running on python 2.6 then you can try this file https://bootstrap.pypa.io/2.6/get-pip.py (it is from same instruction you used, it is a simple python script which installs all dependencies and pip itself) and run it with command python get-pip.py --user

I can run the code below in Pycharm without issues, but when I create an exe using pyinstaller, I get the following error when I run the executable -
**Traceback (most recent call last):
File "openfile.py", line 1, in <module>
ImportError: No module named yaml
[1296] Failed to execute script openfile**
import yaml
from sys import exit
cfg = yaml.safe_load(open("Config.yml"))
exit()
Note that I'm using Windows 10.
pip install pyyaml will solve this problem
or use virtualenv
pip install virtualenv -p python3 #or python2
virtualenv venv
venv/Scripts/activate
pip install pyyaml
when I request using "playsound" library for Python to play the audio
file .mp3 it returns me the following error:
Code:

playsound.playsound("test.mp3")
Error:

The most simple way is the vext approach.
pip install vext
pip install vext.gi

How do I install python3-gi within virtualenv?
It seems like you are using an anaconda environment. I also faced this issue and fixed it by doing the following:
First, create a symlink to gi module in your system Python. For me, the command is as follows:
ln -s /usr/lib/python3/dist-packages/gi/ /home/USERNAME/miniconda3/lib/python3.7/site-packages/
Then, open the directory:
cd /home/USERNAME/miniconda3/lib/python3.7/site-packages/gi/
and run the following commands:
sudo cp _gi.cpython-35m-x86_64-linux-gnu.so _gi.cpython-37m-x86_64-linux-gnu.so
sudo cp _gi_cairo.cpython-35m-x86_64-linux-gnu.so _gi_cairo.cpython-37m-x86_64-linux-gnu.so
My system Python is 3.5 and miniconda Python is 3.7. Your versions may differ from mine, so take care of that in the commands above (-35m- and -37m-).

I try to upgrade pip within a virtualenv following the instructions here. The upgrade fails because the system python cannot import the name Message from the email module.
(newsfeed)myhost:newsfeed admin$ pip install --upgrade pip
Traceback (most recent call last):
File "/Users/admin/newsfeed/newsfeed/bin/pip", line 7, in <module>
from pip import main
File "/Library/Python/2.7/site-packages/pip/__init__.py", line 9, in <module>
from pip.log import logger

from pip import backwardcompat
File "/Library/Python/2.7/site-packages/pip/backwardcompat/__init__.py", line 69, in <module>
from email import Message as emailmessage
ImportError: cannot import name Message
This problem is not just with upgrading pip but with installing anything within the virtualenv. When new package installations are attempted the same error occurs.
In a python terminal outside the virtualenv Message cannot be imported, but inside the virtualenv it can.
Also, in a different virtualenv on the same machine, there is no error installing or upgrading packages.
Why can't this virtualenv upgrade or install packages?
The standard library's email package is being shadowed (hidden) by a package or module named email(.py) in your path.
Locate the package by calling
python -c 'import email;print(email.__file__)'
and rename it or remove it.
Your pip is not inside the venv so you will probably not be able to upgrade it like this.
This is caused by the fact that you created a venv that uses system-packages. Remove the venv and recreate it by adding --no-site-packages as a parameter.
Followed instructions on the github page. Of course, had to make minor changes since I was working with a windows 7 system. I got to the point post creating the virtual environment for portia to run. And I was trying to install the required packages using pip.
pip install -r requirements.txt
It failed with a log.
Now in the shell I try to run twistd, it gives error saying command not found. I even tried as follows:
deostroll#DEOTOP /c/Portia/portia/slyd (master)
$ python ../../portia_env/Scripts/twistd.py -n slyd
Traceback (most recent call last):
File "../../portia_env/Scripts/twistd.py", line 13, in <module>

_checkRequirements()

raise ImportError(required + ": no module named zope.interface.")
ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zop
e.interface.
(portia_env)
deostroll#DEOTOP /c/Portia/portia/slyd (master)
$
Is there an alternate procedure to follow in order to make this work on windows?
It looks like zope.interface didn't install when you ran:
pip install -r requirements.txt
Could you try running the following and see if it works?
pip install zope.interface
When I install bcfg2 - http://bcfg2.org using
pip install git+git://git.mcs.anl.gov/bcfg2.git#egg=Bcfg2
or
pip install bcfg2
I am able to get bcfg2 working. Calling sudo bcfg2-admin init, shows me the set-up configuration steps/stdin prompt as expected.
When I introduce the -e option like this (in a new/clean virtualenv),
pip install -e git+git://git.mcs.anl.gov/bcfg2.git#egg=Bcfg2
And I attempt to call sudo bcfg2-admin init, I get an error message:-
calvin$ bcfg2-admin init
Traceback (most recent call last):
File "/Users/calvin/.virtualenvs/bcfg2/bin/bcfg2-admin", line 7, in <module>

File "/Users/calvin/.virtualenvs/bcfg2/src/bcfg2/src/sbin/bcfg2-admin", line 6, in <module>
import Bcfg2.Server.Core
ImportError: No module named Bcfg2.Server.Core
This leads me to think that there is something wrong with the way setup.py is written for bcfg2. The file is located here - https://github.com/Bcfg2/bcfg2/blob/master/setup.py
Appreciate any input from pythonistas who are experts with python packaging and the configuration of setup.py.
You've installed to a virtual environment (-e). However when you run this with sudo python gets executed as root without the virtual environment available.
If you run sudo su you should be dropped into a root shell. You can then activate the virtual environment and run bcfg2-admin.
The setup.py has a bug.
Figured it out, fixed it and sent a pull request to bcfg2 maintainers.
