Can't upgrade pip in windows [duplicate]

On Windows, if you try to use pip to upgrade itself, inside a virtualenv, you may get a mysterious "access is denied" error. For instance:
D:\scratch\> C:\Program Files\Python\3.7.4\x64\python.exe -m venv D:\scratch\my-venv
D:\scratch\> D:\scratch\my-venv\Scripts\activate
(my-venv) D:\scratch\> pip install --upgrade pip
Collecting pip

Found existing installation: pip 19.0.3
Uninstalling pip-19.0.3:
Could not install packages due to an EnvironmentError:
[WinError 5] Access is denied: 'd:\\scratch\\my-venv\\scripts\\pip.exe'
Consider using the `--user` option or check the permissions.
This happens whether or not the command prompt has administrative privileges.
We know we have write access to everything inside d:\scratch\my-venv, because we just created it with the initial python -m venv command. The advice to use the --user option is unhelpful, since we want to upgrade the version of pip inside the virtualenv, which --user will not do.
What could be wrong, and what is the correct way to upgrade pip inside a virtualenv on Windows?

I don't know if this is the only reason this can happen, but notice that the "Access is denied" error points at d:\scratch\my-venv\scripts\pip.exe. pip is trying to replace itself, and Windows doesn't allow you to modify a running EXE file in any way.
A workaround for this specific problem is to use python -m pip install --upgrade pip instead. This way, pip.exe is not running, so Windows will allow it to be replaced. This action doesn't try to overwrite d:\scratch\my-venv\scripts\python.exe, and Windows doesn't care what pip does to all the other files belonging to the pip package.
See https://github.com/pypa/pip/issues/188 and https://github.com/pypa/pip/issues/1299 for further information.

You must have the same version of pip installed in windows as in the virtual env. I think that is the reason for the error Access Denied in Virtual Env.
in promt,
python -m pip install --upgrade pip
located in the Scripts folder of the virtual env, execute the update command upgrade pip in venv

I would have put this in a comment to zwol's answer, but I don't have enough reputation yet.
I just wanted to add to anyone else potentially coming across this from google like I did, that python -m pip install --upgrade pip did fix this issue for me. However if you try pip install --upgrade pip before doing that, something happens in the process before you hit the access denied error that messes up pip. I personally was getting ModuleNotFoundError: No module named 'pip' after trying to upgrade the normal way.
Once I deleted and restarted my virtualenv and had the first command be python -m pip install --upgrade pip It worked just fine.
I hope that helps other newbies out there struggling like me! :)

Same error for me, but in both conditions: my system pip and virtualenv pip. So, when I tried to upgrade my system pip, hopefully it wasn't like totally deleted, I could still use the "pip" command. However I know the upgrade system pip failed. When I tried the command again, it said pip was on the latest version. Maybe this is just a glitch. I believe it is the same for virtual environments(virtualenv, venv). When I upgrade the system pip I get this error:
ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: 'C:\\Users\\heewo\\AppData\\Local\\Temp\\pip-uninstall-8ob_krif\\pip.exe'
Consider using the `--user` option or check the permissions.
I know this is not normal. But still, different than the virtualenv, "pip" is still installed. I believe this is still ignorable as this is just a known issue and most people here know about this topic. For me, python -m pip install --upgrade pip did not work in this state.
I tried this method, and this did work for me.
virtualenv --pip [VERSION]
and replace VERSION with the latest version available on pip. This prints out that what version you are attempting to upgrade to, when you get the error.
And that should do the trick.

getting error why trying to dffml in development mode?

These are the commands i am running as mentioned in the documentation
git clone https://github.com/intel/dffml
cd dffml
python3 -m pip install -U pip setuptools wheel
python3 -m pip install --prefix=~/.local -e .[dev]
But i am getting warnings and error on the last command
warning
WARNING: Ignoring invalid distribution -jango (/home/dhruv/.local/lib/python3.8/site-packages)
error
Found existing installation: Pillow 7.0.0
Uninstalling Pillow-7.0.0:
ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: '_imagingtk.cpython-38-x86_64-linux-gnu.so'
Consider using the `--user` option or check the permissions.
And program stops executing after the error , i dont know what is the source of error and how to remove it, any help is appreciated

For the error, try using --user, like this:
python3 -m pip install --user -e .[dev]
Their docs talk about why they don't use --user, but the explanation doesn't make much sense to me.
Installing to your home directory will reduce permissions issues. To do this we use the --prefix=~/.local flag. pip sometimes gets confused about the --user flag (and will blow up in your face if you try to pass it). So we use the --prefix=~/.local flag, which has the same effect but should always work.
Specifically, I don't know why pip would "get confused", but I'm not an expert.

Installing requirements via "python -m pip install" randomly throws WinError5 exception

OS: Windows 10, 64-bit
Python: 3.9.1
Pip: 21.0.1
Editor: JetBrains Pycharm 2020.3.3
I have cloned a private GitHub repository via Pycharm and created the project's venv as usual after selecting my project interpreter. Ran python -m pip install -U --force-reinstall pip setuptools wheel after. Versions of all modules are up-to-date.
Pycharm automatically activates the created venv, so there is no need to manually activate it.
When running python -m pip install -r requirements.txt, this error (seemingly) randomly occurs:
ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: {file_path within venv}
Consider using the `--user` option or check the permissions.
I have checked for this error, and all sources seem to imply a permission mismatch, but I cannot figure out why there would be any.
So, I opened cmd as admin, navigated to my project folder and activated the venv through .\venv\Scripts\activate. There was no issue here.
Naturally, I ran python -m pip install -U --force-reinstall -r requirements.txt and the same error still occurred - even with admin permissions. (pip seems to fail randomly - sometimes e.g. numpy is able to be installed, sometimes not)
What could I try next in order to make it work? Have I made any mistakes so far? How could I proceed?
EDIT:
Using the --user flag does not work. ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
EDIT 2:
Deleting the venv directory, and reinstalling it with the following commands seems to have fixed the issue when installing the project requirements for the first time:
python -m venv .\venv
.\venv\Scripts\activate
python -m pip install -U --force-reinstall pip setuptools wheel
python -m pip install -r requirements.txt
The project is able to be run now, but out of curiosity, I tried running this command again:
python -m pip install -U --force-reinstall -r requirements.txt
The error still occurs, so it doesn't seem like the issue is fixed by recreating the venv, but at least the project can be run now. Not closing the question myself, as the "actual problem" does not seem to be fixed.

You probably have the problem, that sometimes code doesn't work due to a very long path.
Try to reinstall python(/the venv python) and search for a point where you can check a box so that the path isn't limited anymore

Permission denied with trying to use pip on MAC?

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/beautifulsoup4-4.6.0.dist-info'Consider using the `--user` option or check the permissions.
The error above is the one I get when I try to use the pip command. All I need to do is pip install the requirements.txt to get my program to work. I have python 2.7.1 installed and placed my code where I am able to use python commands. I tried to change permissions by using this command:
chmod -R 777
but it did not work. I have homebrew installed on my computer. I also tried to use a virtual environment using this link:
http://sourabhbajaj.com/mac-setup/Python/virtualenv.html but it gave me permission issues as well. Is there any suggestions to get rid of this permissions issue and run pip successfully? The sudo command below also doesn't work.
sudo pip install -r requirements.txt

This is a permissions issue.
Consider using pip install "packagename" --user as mentioned in the error.
This is covered HERE

try using sudo pip install djangorestframework for Mac. Worked for me.

It is likely that the directory where the package's entry point was installed is not in your PATH. For example, if it was installed /Users/username/Library/Python/3.7/bin/script, add PATH=$PATH:/Users/username/Library/Python/3.7/bin/ to your shell rc (.bashrc, .bash_profile, etc), and you should be good (and that will solve issues with other scripts installed to that /bin folder.
