(adding this as an answer, because I do not have enough reputation to comment on @blueberryfields 's answer)
@blueberryfields 's answer works well, but fails if there is no package to uninstall (which can be a problem if this "uninstall all" is part of a script or makefile). This can be solved with xargs -r
when using GNU's version of xargs
:
pip freeze --exclude-editable | xargs -r pip uninstall -y
from man xargs
:
-r, --no-run-if-empty
If the standard input does not contain any nonblanks, do not run the command. Normally, the command is run once even if there is no input. This option is a GNU extension.
This is the command that works for me:
pip list | awk '{print $1}' | xargs pip uninstall -y
On Windows if your path
is configured correctly, you can use:
pip freeze > unins && pip uninstall -y -r unins && del unins
It should be a similar case for Unix-like systems:
pip freeze > unins && pip uninstall -y -r unins && rm unins
Just a warning that this isn't completely solid as you may run into issues such as 'File not found' but it may work in some cases nonetheless
EDIT: For clarity: unins
is an arbitrary file which has data written out to it when this command executes: pip freeze > unins
That file that it written in turn is then used to uninstall the aforementioned packages with implied consent/prior approval via pip uninstall -y -r unins
The file is finally deleted upon completion.
In my case, I had accidentally installed a number of packages globally using a Homebrew-installed pip
on macOS. The easiest way to revert to the default packages was a simple:
$ brew reinstall python
Or, if you were using pip3
:
$ brew reinstall python3
If you are using pew
, you can use the wipeenv command:
pew wipeenv [env]
If you're running virtualenv
:
virtualenv --clear </path/to/your/virtualenv>
for example, if your virtualenv is /Users/you/.virtualenvs/projectx
, then you'd run:
virtualenv --clear /Users/you/.virtualenvs/projectx
if you don't know where your virtual env is located, you can run which python
from within an activated virtual env to get the path
First, add all package to requirements.txt
pip freeze > requirements.txt
Then remove all
pip uninstall -y -r requirements.txt
I use the --user option to uninstall all the packages installed in the user site.
pip3 freeze --user | xargs pip3 uninstall -y
In Command Shell of Windows, the command
pip freeze | xargs pip uninstall -y
won't work. So for those of you using Windows, I've figured out an alternative way to do so.
pip freeze
command to a .txt file.pip uninstall -r *textfile.txt*
the easy robust way cross-platform and work in pipenv as well is:
pip freeze
pip uninstall -r requirement
by pipenv:
pipenv run pip freeze
pipenv run pip uninstall -r requirement
but won't update piplock or pipfile so be aware
I wanted to elevate this answer out of a comment section because it's one of the most elegant solutions in the thread. Full credit for this answer goes to @joeb.
pip uninstall -y -r <(pip freeze)
This worked great for me for the use case of clearing my user packages folder outside the context of a virtualenv which many of the above answers don't handle.
Edit: Anyone know how to make this command work in a Makefile?
I add this to my bash profile for convenience:
alias pipuninstallall="pip uninstall -y -r <(pip freeze)"
Then run:
pipuninstallall
If you happen to be using pipenv you can just run:
pipenv uninstall --all
For Windows users, this is what I use on Windows PowerShell
pip uninstall -y (pip freeze)
This works with the latest. I think it's the shortest and most declarative way to do it.
virtualenv --clear MYENV
But usually I just delete and recreate the virtualenv since immutability rules!
pip3 freeze --local | xargs pip3 uninstall -y
The case might be that one has to run this command several times to get an empty pip3 freeze --local
.
I managed it by doing the following:
Create the requirements file called reqs.txt with currently installed packages list
pip freeze > reqs.txt
then uninstall all the packages from reqs.txt
pip uninstall \
-y # remove the package with prompting for confirmation
-r reqs.txt
I like this method as you always have a pip requirements file to fall back on should you make a mistake. It's also repeatable.
The quickest way is to remake the virtualenv completely. I'm assuming you have a requirements.txt file that matches production, if not:
# On production:
pip freeze > reqs.txt
# On your machine:
rm $VIRTUALENV_DIRECTORY
mkdir $VIRTUALENV_DIRECTORY
pip install -r reqs.txt
pip freeze
)pip freeze | xargs pip uninstall -y
pip list
)pip list | awk '{print $1}' | xargs pip uninstall -y
virtualenv
)virtualenv --clear MYENV
This will work for all Mac, Windows, and Linux systems. To get the list of all pip packages in the requirements.txt file (Note: This will overwrite requirements.txt if exist else will create the new one, also if you don't want to replace old requirements.txt then give different file name in the all following command in place requirements.txt).
pip freeze > requirements.txt
Now to remove one by one
pip uninstall -r requirements.txt
If we want to remove all at once then
pip uninstall -r requirements.txt -y
If you're working on an existing project that has a requirements.txt
file and your environment has diverged, simply replace requirements.txt
from the above examples with toberemoved.txt
. Then, once you have gone through the steps above, you can use the requirements.txt
to update your now clean environment.
And For single command without creating any file (As @joeb suggested).
pip uninstall -y -r <(pip freeze)
This was the easiest way for me to uninstall all python packages.
from pip import get_installed_distributions
from os import system
for i in get_installed_distributions():
system("pip3 uninstall {} -y -q".format(i.key))
Cross-platform support by using only pip
:
#!/usr/bin/env python
from sys import stderr
from pip.commands.uninstall import UninstallCommand
from pip import get_installed_distributions
pip_uninstall = UninstallCommand()
options, args = pip_uninstall.parse_args([
package.project_name
for package in
get_installed_distributions()
if not package.location.endswith('dist-packages')
])
options.yes = True # Don't confirm before uninstall
# set `options.require_venv` to True for virtualenv restriction
try:
print pip_uninstall.run(options, args)
except OSError as e:
if e.errno != 13:
raise e
print >> stderr, "You lack permissions to uninstall this package.
Perhaps run with sudo? Exiting."
exit(13)
# Plenty of other exceptions can be thrown, e.g.: `InstallationError`
# handle them if you want to.
Other answers that use pip list
or pip freeze
must include --local
else it will also uninstall packages that are found in the common namespaces.
So here are the snippet I regularly use
pip freeze --local | xargs pip uninstall -y
Ref: pip freeze --help
Its an old question I know but I did stumble across it so for future reference you can now do this:
pip uninstall [options] <package> ...
pip uninstall [options] -r <requirements file> ...
-r, --requirement file
Uninstall all the packages listed in the given requirements file. This option can be used multiple times.
from the pip documentation version 8.1
Pip has no way of knowing what packages were installed by it and what packages were installed by your system's package manager. For this you would need to do something like this
for rpm-based distros (replace python2.7 with your python version you installed pip with):
find /usr/lib/python2.7/ |while read f; do
if ! rpm -qf "$f" &> /dev/null; then
echo "$f"
fi
done |xargs rm -fr
for a deb-based distribution:
find /usr/lib/python2.7/ |while read f; do
if ! dpkg-query -S "$f" &> /dev/null; then
echo "$f"
fi
done |xargs rm -fr
then to clean up empty directories left over:
find /usr/lib/python2.7 -type d -empty |xargs rm -fr
I found the top answer very misleading since it will remove all (most?) python packages from your distribution and probably leave you with a broken system.
I simply wanted to remove packages installed by the project, and not other packages I've installed (things like neovim
, mypy
and pudb
which I use for local dev but are not included in the app requirements). So I did:
cat requirements.txt| sed 's/=.*//g' | xargs pip uninstall -y
which worked well for me.
