I tried to install Pylint in my VS Code using the following command:
pip install pylint
and the output was this:
Requirement already satisfied: pylint in c:\users\domin\appdata\roaming\python\python39\site-packages (2.6.0)

and it only returns the simple cursor:
PS C:\Users\domin>
And whenever I try to use it, VS Code returns the following message:

What should I do?
This output shows you, that you've already got this package and it's dependencies installed in site-packages of python 3.9.
If you need to install it with specific python version installed on your machine you shold type following:
/path/to/your/bin/python -m pip install pylint
Same with virtualenv. If you want to install it into virtualenv python:
source mypython/bin/activate
pip install pylint
First answer is to put python on PATH, If that does not work you can go to the user settings (in vs code) and edit the "python.linting.pylintEnabled" to True.
If even that does not work then:-
Copy the path where pylint is installed on your computer.
Go to your vs code settings and click on the preferences tab.
Edit this line
"python.linting.pylintPath": "pylint"
replace pylint with the path of your pylint installation.

Abstract
I have installed pyinstaller.
pip install pyinstaller
This is probably a successful installation.
When I ran the same command again, this is what I got.
Areas marked in black are personal information.
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

What I tried
First, we typed the following command.

It then returned the following

It is not recognized as an operable program or batch file.

I followed without fail and typed the following commands.

It then returned the following

Why you got that error:
You got that error message because you are trying to open error404.py file with a cd command, the cd command is used for navigating through directories and error404.py is a file not a directory.
To navigate or change directory:
Your working directory is C:\Users\lucy22. So there is no need to include that in you command.
You should rather write the below command and that will take you to the firstprog directory where your error404.py file is located.:
cd PycharmProjects\firstprog
To open a file:
If you are looking to open error404.py file, you should use the open command.
Example:
open PycharmProjects\firstprog\error404.py
I'm using Windows 10.
In my project folder, I'm trying to test it as an exe.
So, I did this to install Pyinstaller:
py -m pip install pyinstaller
And it said it installed.
But when I did py -m pyinstaller emu.py, it just returned this:
C:\Users\tux\AppData\Local\Programs\Python\Python310\python.exe: No module named pyinstaller
Can someone help?
If I try to install pyinstaller using PIP again, it comes up with this error:

It's saying Pyinstaller is already installed, but python doesn't recognise it.
Before you ask, if I try to just run pyinstaller as a standalone command, it says it cannot find pyinstaller.
Edit: It's been over a month and nobody has replied.
Forget it. I'm just not gonna make the application.
Did you try the generic way
pip install pyinstaller

it worked on my computer,i think its not working on your computer because you haven't added it to system variables(PATH),here's how you can do so
pytest and other scripts are mostly present in a directory(in python folder) named 'Scripts'.maybe yours is somewhere else and if so then type pytest.exe in start menu and copy the file location and add it to system variables.if this doesnt work try re-installing pytest or python.
Edit:if you check the output pip is telling you that WARNING: The scripts py.test.exe and pytest.exe are installed in 'C:\Users\sbhandari\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.just add the directory above on your path and it should solve your problem
I am running Catalina MacOS with python 3.7.5. I am trying to run an ansible script to install a VM. This Requires python >= 2.6 and PyVmomi. I have installed PyVomi and pyVim via pip. Both were installed successfully. When I run the playbook, I get the error message below. Not sure what I am missing.
TASK [Create a virtual machine on given ESXi hostname] *************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ImportError: No module named pyVim
fatal: [localhost -> localhost]: FAILED! => {"changed": false, "msg": "Failed to import the required Python library (PyVmomi) on MacBook-Pro.local's Python /System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python. Please read module documentation and install in the appropriate location"}
ArunJose_Intel is correct. The module is pyvmomi, not pyVim. Although the error indicates that the pyVim library was missing. It was misleading as I could see it in my directory. Following his advice I changed the pip install command to install pyvmomi instead.
pip install pyvmomi
I was able to run the python script with pyVim imported. Thank you Arun.
You might have installed PyVomi and pyVim for the wrong python executable. You have to make sure you are installing via pip to the right python. You are installing the packages to the python3.x present in your machine. What you have to do is to install the pip packages to the python of the playbook
I fixed it.
pip3 install ansible
That made ansible use python3
Sorry for the confusion. I have installed this via pip3, is yes they are installed in the python3 directories.
