是否可以使用pip一次性升级所有Python包?

注意:官方问题跟踪器上对此有一个功能请求。

改用pipx:

pipx upgrade-all

相当惊人的蛋黄使这很容易。

pip install yolk3k # Don't install `yolk`, see https://github.com/cakebread/yolk/issues/35
yolk --upgrade

它可以做很多你可能会发现有用的事情。

这似乎对我有用。。。

pip install -U $(pip list --outdated | awk '{printf $1" "}')

之后,我使用带有空格的printf来正确分隔包名。

使用pip升级程序

使用该库,您可以轻松升级所有依赖项包这些是您遵循的设置。

pip安装pip升级程序

pip升级路径/of/requirements_txt_file

交互式pip需求升级程序。因为逐包升级需求是件麻烦事。它还会更新requirements.txt文件中的版本。

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。

@echo off
Setlocal EnableDelayedExpansion
rem https://stackoverflow.com/questions/2720014/

echo Upgrading pip...
python -m pip install --upgrade pip
echo.

echo Upgrading packages...
set upgrade_count=0
pip list --outdated > pip-upgrade-outdated.txt
for /F "skip=2 tokens=1,3 delims= " %%i in (pip-upgrade-outdated.txt) do (
    echo ^>%%i
    set package=%%i
    set latest=%%j
    set requirements=!package!

    rem for each outdated package check for any version requirements:
    set dotest=1
    for /F %%r in (.\python\requirements.txt) do (
        if !dotest!==1 (
            call :substr "%%r" !package! _substr
            rem check if a given line refers to a package we are about to upgrade:
            if "%%r" NEQ !_substr! (
                rem check if the line contains more than just a package name:
                if "%%r" NEQ "!package!" (
                    rem set requirements to the contents of the line:
                    echo requirements: %%r, latest: !latest!
                    set requirements=%%r
                )
                rem stop testing after the first instance found,
                rem prevents from mistakenly matching "py" with "pylint", "numpy" etc.
                rem requirements.txt must be structured with shorter names going first
                set dotest=0
            )
        )
    )
    rem pip install !requirements!
    pip install --upgrade !requirements!
    set /a "upgrade_count+=1"
    echo.
)

if !upgrade_count!==0 (
    echo All packages are up to date.
) else (
    type pip-upgrade-outdated.txt
)

if "%1" neq "-silent" (
    echo.
    set /p temp="> Press Enter to exit..."
)
exit /b


: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

以下命令在Windows上运行,对其他人也很有用($是命令提示符下的任何目录。例如,C:\Users/Username)。

Do

$ pip freeze > requirements.txt

打开文本文件,将==替换为>=,或让sed为您执行以下操作:

$ sed -i 's/==/>=/g' requirements.txt

并执行:

$ pip install -r requirements.txt --upgrade

如果您对某个软件包延迟升级有问题(有时是NumPy),只需转到目录($),注释掉名称(在其前面添加#),然后再次运行升级。稍后可以取消注释该部分。这对于复制Python全局环境也非常有用。


另一种方式:

我也喜欢pip审查方法:

py2
$ pip install pip-review

$ pip-review --local --interactive

py3
$ pip3 install pip-review

$ py -3 -m pip-review --local --interactive

您可以选择“a”来升级所有软件包;如果一次升级失败,请再次运行,然后在下一次升级中继续。
