First you need to add python to path (like in this answer
Then you need to install pip and setuptools to correctly install packages
And after try install your package

Why does "pip install" inside Python raise a SyntaxError?
(7 answers)
Closed last month.
When I try to install packages, e.g. pypdf2, I get a syntax error:
I tried to change the environment variables like is done in other questions on this topic but I do not succeed in solving this problem. Can someone provide a step-by-step walkthrough in solving this problem for a Python beginner?
You are trying to execute pip install as if it is a python command: but it isn't.
You need to execute all pip commands from the normal O/S command line - since you are in Pycharm you can simply type those pip commands from the Terminal window (the one you used to try to run the script).

(using 'imgkit' on Ubuntu server) wkhtmltopdf: could not connect to any X display
(2 answers)
Closed 2 years ago.
I have installed a Python library called eml2png. This library has a dependency on "wkhtmltopdf" which I have also installed. When I try making a call, I get the following error:
You need to install xvfb(sudo apt-get install xvfb, yum install xorg-x11-server-Xvfb, etc), then add option: {"xvfb": ""}.
I have installed this library, but I have no idea where I add the option {"xvfb": ""}. Can someone please explain this?
Thanks
After a quick look at the source (https://github.com/poipoii/eml2png/blob/master/src/eml2png/eml2png.py) I suggest trying:
eml2png.to_png('message.eml', options={"xvfb": "", "format": "png"})

pip how to remove incorrectly installed package with a leading dash: "-pkgname"
(4 answers)
Closed 2 years ago.
I have tried to do the standard
pip freeze > requirements.txt and got
Could not parse requirement: -pencv-python
I then found out pip actually thinks this is the installed package
Notice the 1st line.
How do I get rid of this and get a requirements file?
For some reason, venv\Lib\site-packages had a folder ~pencv_python-4.2.0.34.dist-info, which was unused, due to opencv_contrib_python-4.2.0.34.dist-info also being present.
I removed it and it worked.
Windows, if anyone cares.

How do I use installed packages in PyCharm?
(14 answers)
Closed 5 months ago.
Successfully installed the openpyxl module with pip. It imports no problem on the python terminal, but imports fail in Pycharm.
Thought I might have messed up the installation so uninstalled the module and reinstalled.
After reinstalling the second time, checked if python recognized the module and if it works. It passed both those checks. But when using Pycharm and using the import command it doesn't work.
Hoping someone with more experience with Pycharm can help. Attached related screenshots below. I am using Python 3.7 (32-bit).
If I am missing any information or breaking any rules please let me know.

Getting Python error "from: can't read /var/mail/Bio"
(6 answers)
Closed 9 months ago.
I'm new to Python and also new to Linux. I want to know why this code doesn't work?
(gmapenv)teruun#ubuntu:~/gmapenv$ python -c 'import googlemaps'
(gmapenv)teruun#ubuntu:~/gmapenv$ from googlemaps import GoogleMaps
and it says:
from: can't read /var/mail/googlemaps
what does this mean? what does from: can't read mean?
You need to install whatever Python libraries using e.g. pip or easy_install before you can import the googlemaps module in your Python code. This is because there is no GoogleMaps library that is built in to the Python standard library. I see you've already gotten started with using virtualenv, which is good. Also, perhaps you already installed a library, but maybe you installed the wrong one, or you installed it globally and then created a virtualenv, which by default is isolated from your globally installed packages. So either create a non-isolated virtualenv (not recommended) or install the package into the virtualenv (and uninstall globally).
Also, the second line you posted attempts to execute Python code directly on Bash, which doesn't work for obvious reasons, and gives a cryptic error message because Bash thinks you're expecting it to be a Bash command, and it just so happens that from actually is a command.
