在安装 pip 包时，我刚刚安装了全新安装的 BigSur 和 Python（使用 asdf），它们似乎最终会出现在：
./.asdf/installs/python/3.9.2/lib/python3.9/site-packages
which flake8例如，当我输入时，flake8 not found但当我再次安装它时，pip install flake8我得到以下信息：
> which flake8
flake8 not found
~
> pip install flake8
Requirement already satisfied: flake8 in ./.asdf/installs/python/3.9.2/lib/python3.9/site-packages (3.8.4)
Requirement already satisfied: pycodestyle<2.7.0,>=2.6.0a1 in ./.asdf/installs/python/3.9.2/lib/python3.9/site-packages (from flake8) (2.6.0)
Requirement already satisfied: mccabe<0.7.0,>=0.6.0 in ./.asdf/installs/python/3.9.2/lib/python3.9/site-packages (from flake8) (0.6.1)
Requirement already satisfied: pyflakes<2.3.0,>=2.2.0 in ./.asdf/installs/python/3.9.2/lib/python3.9/site-packages (from flake8) (2.2.0)
我刚刚尝试使用我安装的请求，使用pip install requests时也找不到，which但我设法在 VSC 中使用该包。
我正在使用 flake8 和 Black，我需要为 VSC 提供它们的路径。我用过
./.asdf/installs/python/3.9.2/lib/python3.9/site-packages/<package name>
但 VSC 似乎并没有解决这个问题。我正在使用最新版本。
> python -V
Python 3.9.2
~
> pip -V
pip 21.0.1 from /Users/paul/.asdf/installs/python/3.9.2/lib/python3.9/site-packages/pip (python 3.9)
这也可能有帮助：
~
> which python
/Users/paul/.asdf/shims/python
~
> which pip
/Users/paul/.asdf/shims/pip
知道如何which显示正确的路径，以便让我的列表和格式正常工作吗？
