在 Mac 上找不到 Python 3 文件夹？

Question

I'm unable to find the python 3 folder on my Mac (Mojave). I have installed it correctly, and I've tried to reinstall it with but it says that it is already installed. I even installed a package (Mendel-development-tool) on it. Through my checking of the Mendel-development-tool (trying to uninstall it), it states that I have a folder with this:

/Users/username/Library/Python/3.7/bin/mdt

But, when I enter this path into my terminal, it shows python 2.7. And, when I look through to the site packages, mdt isn't there, and when I look through my library folder and see python, the only thing there is 2.7.

Does anyone know a fix to this?

Answer 1

It's not clear how you installed python, but it could literally be installed anywhere on disk

If you want to find something use the find command

sudo find ~ -type f -name mdt

If that returns nothing, then mdt is not in your home folder

You can also find all directories with Python in the name

sudo find ~ -type d -iname '*python*' 

Answer 2

There may not be a python3 folder. What you probably want is the python3 application. Type

which python3

and see what you get. In my case, I get the location of the python3 application. I also have the application python3.7. Once you find the location of these apps you can make sure the location is in your PATH.

Installing a python version does not create a python folder.
