简单有力的方法 跨平台的 在pipenv的工作也是:

pip freeze 
pip uninstall -r requirement

pipenv:

pipenv run pip freeze 
pipenv run pip uninstall -r requirement

但不会更新piplock或pipfile，所以要注意

这是我卸载所有python包的最简单的方法。

from pip import get_installed_distributions
from os import system
for i in get_installed_distributions():
    system("pip3 uninstall {} -y -q".format(i.key))

最快的方法是完全重做virtualenv。我假设你有一个符合生产的requirements.txt文件，如果没有的话:

# On production:
pip freeze > reqs.txt

# On your machine:
rm $VIRTUALENV_DIRECTORY
mkdir $VIRTUALENV_DIRECTORY
pip install -r reqs.txt

这在Windows上很管用:

pip uninstall -y (pip freeze)

仅使用pip的跨平台支持:

#!/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.
