推荐答案

以下内容适用于 Windows，也适用于其他人($ 是您所在的任何目录，在命令提示符下. 例如，C:/Users/Username).

The following works on Windows and should be good for others too ($ is whatever directory you're in, in the command prompt. For example, C:/Users/Username).

做

$ pip freeze > requirements.txt

打开文本文件，将 == 替换为 >=，或者让 sed 为你做:

Open the text file, replace the == with >=, or have sed do it for you:

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

并执行:

$ pip install -r requirements.txt --upgrade

如果您遇到某个包延迟升级的问题(有时NumPy)，只需转到目录 ($)，注释掉名称(在它之前添加 #)并再次运行升级.您可以稍后取消对该部分的注释.这也非常适合复制 Python 全局环境.

If you have a problem with a certain package stalling the upgrade (NumPy sometimes), just go to the directory ($), comment out the name (add a # before it) and run the upgrade again. You can later uncomment that section back. This is also great for copying Python global environments.

另一种方式:

我也喜欢 pip-review 方法:

I also like the pip-review method:

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"升级所有软件包；如果一次升级失败，请再次运行，并在下一次继续.

You can select 'a' to upgrade all packages; if one upgrade fails, run it again and it continues at the next one.
