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

如果您安装了pip<22.3,则使用纯Bash/Z外壳一个衬垫实现:
for p in $(pip list -o --format freeze); do pip install -U ${p%%=*}; done
或者,以一种格式良好的方式:
for p in $(pip list -o --format freeze)
do
pip install -U ${p%%=*}
done
在这之后,您将得到pip>=22.3,其中-o和--format冻结是互斥的,您不能再使用这一行。
从…起https://github.com/cakebread/yolk:
$ pip install -U `yolk -U | awk '{print $1}' | uniq`
然而,你需要先得到蛋黄:
$ sudo pip install -U yolk
如果您希望升级仅由pip安装,并且避免升级由其他工具(如apt、yum等)安装的软件包,那么您可以使用我在Ubuntu上使用的脚本(可能也适用于其他发行版)-基于以下帖子:
printf "To update with pip: pip install -U"
pip list --outdated 2>/dev/null | gawk '{print $1;}' | while read; do pip show "${REPLY}" 2>/dev/null | grep 'Location: /usr/local/lib/python2.7/dist-packages' >/dev/null; if (( $? == 0 )); then printf " ${REPLY}"; fi; done; echo
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pip list --outdated --format=columns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
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
