Windows PowerShell解决方案

pip freeze | %{$_.split('==')[0]} | %{pip install --upgrade $_}

您可以使用以下Python代码。与pip冻结不同，这不会打印警告和FIXME错误。对于管道<10.0.1

import pip
from subprocess import call

packages = [dist.project_name for dist in pip.get_installed_distributions()]
call("pip install --upgrade " + ' '.join(packages), shell=True)

对于pip>=10.0.1

import pkg_resources
from subprocess import call

packages = [dist.project_name for dist in pkg_resources.working_set]
call("pip install --upgrade " + ' '.join(packages), shell=True)

pip_upgrade_outdated（基于此旧脚本）完成此任务。根据其文件：

usage: pip_upgrade_outdated [-h] [-3 | -2 | --pip_cmd PIP_CMD]
                            [--serial | --parallel] [--dry_run] [--verbose]
                            [--version]

Upgrade outdated python packages with pip.

optional arguments:
  -h, --help         show this help message and exit
  -3                 use pip3
  -2                 use pip2
  --pip_cmd PIP_CMD  use PIP_CMD (default pip)
  --serial, -s       upgrade in serial (default)
  --parallel, -p     upgrade in parallel
  --dry_run, -n      get list, but don't upgrade
  --verbose, -v      may be specified multiple times
  --version          show program's version number and exit

步骤1：

pip install pip-upgrade-outdated

第2步：

pip_upgrade_outdated

通过拉取请求发送给pip人员；同时使用我写的这个pip库解决方案：

from pip import get_installed_distributions
from pip.commands import install

install_cmd = install.InstallCommand()

options, args = install_cmd.parse_args([package.project_name
                                        for package in
                                        get_installed_distributions()])

options.upgrade = True
install_cmd.run(options, args)  # Chuck this in a try/except and print as wanted

Windows上最短、最简单的。

pip freeze > requirements.txt && pip install --upgrade -r requirements.txt && rm requirements.txt

查看所有过时的软件包

 pip list --outdated --format=columns

安装

 sudo pip install pipdate

然后键入

 sudo -H pipdate
