copying modules from python 3.10 to 3.11 (does not work)

问题

I am trying to copy modules from python 3.10 to 3.11.
I am using windows 11.

  • My understanding is that one just downloads and install the new version of python.
  • I make sure that python is added to path.

I follow this instruction: https://stackoverflow.com/questions/74190755/copying-modules-from-python-3-10-to-3-11

I then do this:

python3.10 -m pip freeze > requirements.txt
python3.11 -m pip install -r requirements.txt

But it throws an error message:

'python3.10' is not recognized as an internal or external command, operable program or batch file.

So I do this:

where python

To get this:

C:\Users\admin\AppData\Local\Programs\Python\Python311\python.exe
C:\Users\admin\AppData\Local\Programs\Python\Python310\python.exe
C:\Users\admin\AppData\Local\Programs\Python\Python39\python.exe
C:\Users\admin\AppData\Local\Microsoft\WindowsApps\python.exe

I note the guidance here: https://pip.pypa.io/en/stable/cli/pip_freeze/
which states this:

env1\bin\python -m pip freeze > requirements.txt
env2\bin\python -m pip install -r requirements.txt

So my question is, with my paths and the above instruction, how do I implement the correct command so that all the packages are successfully updated in the new python version?

update:

Is this the correct implementation?

C:\Users\admin\AppData\Local\Programs\Python\Python310\python -m pip freeze > requirements.txt
C:\Users\admin\AppData\Local\Programs\Python\Python311\python -m install -r requirements.txt

And if so, do I need to copy the requirements.txt file to the new path?

你可以指定 Python 的完整路径,

C:\Users\admin\AppData\Local\Programs\Python\Python310\python.exe -m pip freeze > requirements.txt
C:\Users\admin\AppData\Local\Programs\Python\Python311\python.exe -m pip install -r requirements.txt

或者更好的做法是在相同目录下为 Python 创建一个链接,

cd C:\Users\admin\AppData\Local\Programs\Python\
mklink Python310\python3.10.exe Python310\python.exe
mklink Python311\python3.11.exe Python311\python.exe

之后,当你想要使用 python3.xx 时,只需键入 python3.xx 即可。现在你可以使用相同的命令。

英文:

You can specify full path of python,

C:\Users\admin\AppData\Local\Programs\Python\Python310\python.exe -m pip freeze > requirements.txt
C:\Users\admin\AppData\Local\Programs\Python\Python311\python.exe -m pip install -r requirements.txt

or It would be better for you to create a link for python in the same directory,

cd C:\Users\admin\AppData\Local\Programs\Python\
mklink Python310\python3.10.exe Python310\python.exe
mklink Python311\python3.11.exe Python311\python.exe

Later on when you want to use python3.xx, just type python3.xx it will work. Now you can use the same command you are using.
