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 pip list --outdated --format=columns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

这是我对rbp答案的变体，它绕过了“可编辑”和开发发行版。它有两个缺点：不必要地重新下载和重新安装；并且一个包上的错误将阻止之后每个包的升级。

pip freeze |sed -ne 's/==.*//p' |xargs pip install -U --

以下Windows cmd代码段执行以下操作：

将pip升级到最新版本。升级所有过时的软件包。对于正在升级的每个包，检查requirements.txt中的任何版本说明符。

:substr
rem string substition done in a separate subroutine -
rem allows expand both variables in the substring syntax.
rem replaces str_search with an empty string.
rem returns the result in the 3rd parameter, passed by reference from the caller.
set str_source=%1
set str_search=%2
set str_result=!str_source:%str_search%=!
set "%~3=!str_result!"
rem echo !str_source!, !str_search!, !str_result!
exit /b

Use:

pip install -r <(pip freeze) --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)

这里有一个脚本，它只更新过时的包。

import os, sys
from subprocess import check_output, call

file = check_output(["pip.exe",  "list", "--outdated", "--format=legacy"])
line = str(file).split()

for distro in line[::6]:
    call("pip install --upgrade " + distro, shell=True)

对于不输出为传统格式的新版本pip（版本18+）：

import os, sys
from subprocess import check_output, call

file = check_output(["pip.exe", "list", "-o", "--format=json"])
line = str(file).split()

for distro in line[1::8]:
    distro = str(distro).strip('"\",')
    call("pip install --upgrade " + distro, shell=True)
