If I uninstall pip with
pip uninstall pip
does it remove all installed packages too?
No. pip is a tool that handles downloading packages and installing them to various locations; those locations are not part of pip's own install directories. As such, removing pip has no effect on installed packages.
(Common paths for installing packages include /usr/lib/<pythonversion> or /usr/local/lib/<pythonversion>.)

When installing Python packages from development repositories, I usually navigate to wherever setup.py is found and do
pip install .
This installs the package in $HOME/.local/. Nice.
How can I uninstall a package installed this way?
Simply run pip uninstall package-name
That's all you need.

I have Python installed in Windows and used pip to install lots of things.
How can I know what packages I installed with pip?
pip list will list all your installed packages.
That's it, I've some package installed using setuptools i.e. I ran the command python setup.py install from the package source.
My question is, how do I uninstall the package or upgrade it?
Install pip using easy_install:
easy_install pip
and then:
pip uninstall <package>
PS. Probably duplicate.
I'm new to virtualenv (on windows). I'm trying to use pip (1.5) install a local wheel file, but it is failing.
The command is:
pip install --no-index -f C:/Users/<User>/Download openpyxl
In the pip.log, I can see where it finds the correct file, but then doesn't try to install it:
Skipping link file:///C:/Users/<User>/Download/openpyxl-1.7.0-py2.py3-none-any.whl; unknown archive format: .whl
I have wheel (version 0.22) install globally as well as in the virtual environment. Any idea how I can get .whl to be a recognized format?
It appears wheel support is disabled.
Make sure that you have setuptools version 0.8 or newer installed, and that the use-wheel option is not set to false in $HOME/.pip/pip.conf.
Upgrading setuptools is easy enough if pip is already working:
pip install --upgrade setuptools
but note that older virtualenv versions can depend on older setuptools versions; you'll need to make sure that virtualenv is also up to date.
I have bumped into the same problem with wheel when downloaded requirements with:
pip install --download /pip_mirror six django_debug_toolbar
dir2pi /pip_mirror/
and tried to install them with:
pip install six-1.7.3-py2.py3-none-any.whl
Even though there is no any config at $HOME/.pip/pip.conf and
$ easy_install --version
setuptools 5.4.1
I still get:
unknown archive format: .whl
I have managed to avoid the problem by adding --no-use-wheel like this, so got only tar.gz files (instead of .whl)
pip install --no-use-wheel --download /pip_mirror six django_debug_toolbar
dir2pi /pip_mirror/
After this pip install --index-url=file:///pip_mirror/simple/ six went without any problems
What are the sequence of steps when we do
$ pip install <package name>
