Use the specified Python version in pdm install

[Well2333]

When I use pdm install command to install dependencies, pdm will use the first available Python interpreter directly, and there is no way to specify which interpreter I want to use.

For instance, if my global default interpreter is Python 3.9 and I want to use 3.8 for compatibility testing, I need to create a virtual environment using pdm venv create python3.8 first, and then install dependencies using pdm install. This seems a bit cumbersome.

Is it possible to add a parameter like --python python3.8 to specify the Python version, just like conda create python=3.8?

Meanwhile, the pdm use command defaults to using PEP 582. Could you consider adding support for venv , just like what poetry use does?

当我尝试使用 pdm install 命令时，pdm会直接使用顺位第一的python解释器，而并没有办法指定用户想要使用的解释器。

例如，我的全局默认解释器是 python3.9，而我想要使用3.8进行兼容性测试，那么我需要首先使用 pdm venv create python3.8 来创建虚拟环境，然后才能 pdm install 进行依赖安装，这显得有一些麻烦

是否可以考虑可以添加参数 --python python3.8 来指定python版本，就像 conda create python=3.8?

同时，pdm use 指令会默认使用 pep582 ，能否考虑在此基础上添加venv的支持，就像 poetry use 一样？

Sorry for not noticing this issue. The keywords I searched using didn't coincide well with the keywords used for this issue, so I missed it. I'll move to this issue for discussion

But my needs are still a little different, the coverage will be relatively small, and the issue about pdm use is not covered in #1705 . However, I think the overlap is still quite large, and you can reopen this issue if you feel that it is valuable to discuss it separately
