VSCode 中的 Python：切换到正确环境的最简单方法是什么？

Question

I am trying to use Python3 in VS code and for some reason, the VS terminal only will read my macOS system installed version of Python 2.7. I have several other interpreters for python3 installed, but I cannot get the VS terminal to access them to install modules and run my program.

I am using the command palette to select the interpreter and it says "current: /path/to/python3".

That is all good, but when I go to terminal to update my packages for I get this error that to me indicates that terminal is trying to install the package in the default python 2.7 environment. How do I access my python3 environments from this terminal? Any help is greatly appreciated!

Answer 1

The best way to avoid this kind of trouble for each project/development environment is virtual environments. Recomended read: https://docs.python-guide.org/dev/virtualenvs/ You can use PipEnv https://github.com/pypa/pipenv or virtual env https://docs.python.org/3/library/venv.html

Answer 2

The issue is that when you select a globally-installed interpreter it doesn't change what python points at in the terminal. You still need to specify either the full path to the interpreter or at least the major.minor version, eg python3.7 to get the interpreter you want.

Otherwise you can use the advice provided by @paltaa and create a virtual environment to work from to isolate your work and put it all directly under your control.

I also find the same problem when I was working on python 3. I Deleted the directory in which python 2.7 was installed. System automatically refer to Python 3 after that.
