windows - pip will not update, install completes successfully but version never changes

I was tired of seeing the warning so figured I'd update pip from 21.0.1 to 21.1.2, however, when using the command D:\Python38\python.exe -m pip install --upgrade pip, or python -m pip install --upgrade pip, the version never changes to 21.1.2. I have restarted my terminal, I have checked my path, the only thing I can think is that I changed the global.cache dir to my D: drive to conserve space on my windows hog of a machine. Here is a snippet from my terminal of what I have going on.

I have scoured the internet for an inkling into why this is happening but I can't seem to find an answer. Thing is, this isn't something that I have to have done, it's just nagging at me that I cant figure it out at this point.
I have read through the pip documentation config file and user guide and of course I have looked for my answer here before asking my question, I hope someone out there can give me some insight and thank you for your time.

Problem downloading (pytube) library in Python

I want to download a library from Python libraries called (pytube)
When I place the download command [pip install git + https: //github.com/pytube/pytube] in the cmd panel, the following output will come out:
Collecting git+https://github.com/pytube/pytube
Cloning https://github.com/pytube/pytube to c:\users\jit\appdata\local\temp\pip-req-build-w3q3fwqn
Requirement already satisfied (use --upgrade to upgrade): pytube==10.6.1 from git+https://github.com/pytube/pytube in c:\users\jit\appdata\local\programs\python\python39\lib\site-packages
Using legacy 'setup.py install' for pytube, since package 'wheel' is not installed.
WARNING: You are using pip version 20.2.3; however, version 21.0.1 is available.
You should consider upgrading via the 'c:\users\jit\appdata\local\programs\python\python39\python.exe -m pip install --upgrade pip' command.
So I write what prompts [pip install --upgrade pip] into the cmd panel, and it gets the following output:
Installing collected packages: pip
Attempting uninstall: pip
Found existing installation: pip 20.2.3
Uninstalling pip-20.2.3:
Successfully uninstalled pip-20.2.3
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'C:\\Users\\jit\\AppData\\Local\\Temp\\pip-uninstall-pnqylmmj\\pip.exe'
Consider using the `--user` option or check the permissions.

And in another attempt to install it, I typed the command in the (Terminal) inside the (PyCharm) program:
Collecting git+https://github.com/pytube/pytube
Cloning https://github.com/pytube/pytube to c:\users\jit\appdata\local\temp\pip-req-build-o5uke_cl
Running command git clone -q https://github.com/pytube/pytube 'C:\Users\jit\AppData\Local\Temp\pip-req-build-o5uke_cl'

And I did not succeed in installing the library! Why is that? How do I get to the solution?

Try installing pytube3. pip install pytube3
for the pip warning it's just a warning because you are not using the latest version , use this command to upgrade it: python -m pip install --upgrade pip

Welcome to Stackoverflow!!!
For pytube as you already installed, try upgrade to latest version pytube-10.6.1:
python -m pip install --upgrade pytube
For pip install --upgrade pip error, this is happening due to insufficient access:
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'C:\\Users\\jit\\AppData\\Local\\Temp\\pip-uninstall-pnqylmmj\\pip.exe'
Solution:
Consider using the `--user` option or check the permissions.
Try:
python -m pip install --upgrade pip --user
Or open the command prompt as administrator and execute the same command.

How to update pip to latest version 20.0.2

While using this command
"python -m pip install --upgrade pip"
I get this error message:
"Collecting pip

WARNING: You are using pip version 19.2.3, however version 20.0.2 is available.

What's the solution to this?

I'm not too sure what the error could be, but I suspect the problem is that you are not running your terminal/command prompt as an administrator. So when you are launching your terminal/command prompt just right-click and run as administrator
Or you could try using a different method of updating pip,
pip install --upgrade pip

Can you try with this command instead ? Also if any issue persists try running cmd as Administrator
python -m pip install --user --upgrade pip

pip install -U setuptools fail windows 10

I just installed Python3.7 and Pycharm on my Windows 10 PC.
I am running pip version 9.0.2
In Pycharm, it says I have version 28.8.0 of setuptools, when I try to upgrade this in Pycharm, which I believe runs the line
pip install -U setuptools
I get the error:
PermissionError: [WinError 32] The process cannot access the file because it
is being used by another process:
'c:\users\Username\pycharmprojects\untitled1\venv\lib\site-
packages\setuptools-28.8.0-py3.6.egg' ->
'C:\Users\Username\AppData\Local\Temp\pip-i5jxitem-
uninstall\users\Username\pycharmprojects\untitled1\venv\lib\site-
packages\setuptools-28.8.0-py3.6.egg'
I have tried running
pip install --upgrade setuptools
which runs successfully and says I have the latest version.
Does anyone know how I can successfully update setuptools?
The reason I'd like setuptools to be up to date, is so I can then get rid of the egg_info error installing other packages.

I have the same error. Not sure why it happened. But I managed to upgrade by running:
pip install setuptools --upgrade --ignore-installed

You can also try:
easy_install --upgrade setuptools
Even though easy_install's deprecated, there's a good chance it'll still work on Windows.
If you try to use pip to upgrade setuptools:
pip install -U setuptools
it seems to get stuck on an error about 10.0 vs 18.0 "You should consider upgrading via the 'python -m pip install --upgrade pip' command."
The official pip doco(https://pip.pypa.io/en/stable/installing/#upgrading-pip) says on Windows to use this:
python -m pip install --upgrade pip
However, it seemed pip and setuptools had a hiccup with a circular dependency or lock around pip-v9.0 or 10.0 to pip-18.0 and setuptools v28.0 to v39.0 or 40.0 so persevere with this:
python -m pip install --force-reinstall pip
You need setuptools >= 39.0 if you want to install pipenv also.

Try the following command to upgrade the setup tools in windows
pip install -U pip setuptools
or
pip install setuptools --upgrade --ignore-installed

I solved more or less similar problem as follow:
In my PyCharm project terminal tab:
`(venv) PS C:/path/to/project>`
updated pip, setup tools and wheels with command:
py -m pip install --upgrade pip setuptools wheel
(source of recommendation)

Pip updates but installs old version

$ pip install -U pip

Successfully installed pip-8.1.1
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
The problem is pretty self-explanatory.
I tell pip to update itself, it gets the 9.0.1 package, installs 8.1.1 somehow then tells me to run the command i just ran to update it.

I managed to fix it by installing pip trough the script given at the website(apt-get installs version 8.1.1):
https://bootstrap.pypa.io/get-pip.py
It automatically uninstalled the old version so everything is in order now.
