如何将python软件包从旧版本安装到新版本? [英] How to install python packages from older version to newer version?

问题描述

我正在使用python 3.7，最近在Linux中安装了python 3.8.

i was working with python 3.7 and i installed recently python 3.8 in linux.

是否有bash命令或脚本采用3.7版所有软件包的列表，并在3.8版中逐一安装.

Is there any bash command or script that take a list of all packages of 3.7 and install it one by one in 3.8 version.

我想避免每个包裹都手工做.

i want to avoid to do it by hand every package.

注意:我不使用venv将它们安装在我的系统中.

Note: i install them in my system not using venv.

谢谢！

推荐答案

/path_to_3.7_bin/python -m pip freeze > /home/packages_list.txt

然后

/path_to_3.8_bin/python -m pip install -r /home/packages_list.txt
