I was having a issue for virtualenv and was trying to make a environment ,my terminal was showing

zsh: command not found: virtualenv

and so I looked for a article about this issue and it said to do this command

and I got allot of error issues,

I decided to make a environment and see what happens

I use 3.10.0 but over here in the error I think it tried to install to version 2.7

I did

pip3 uninstall virtualenv
pip3 install virtualenv

, and tried to make a new environment. Still the same error occurs. I think I messed up 2.7. What should I do?! I am using MacOS if it helps

• joanis: What operating system and distro are you using?
• bool3max: From the directory structure I assume that you are using macOS. You could install virtualenv using Homebrew (see here), or using pip, Python's package manager.
• RetroParody: I have been using pip to install virtualenv
• RetroParody: and I am using MacOS
• OneCricketeer: Please install Python3. Don't install pip into Python2 because it will not work. Also, sudo is never a correct solution to this problem

Answer 1

So it was not possible to do virtualenv environment But python3 -m venv environment I am not sure why it is like this but once I ran the command it seems that it made it into a environment

• OneCricketeer: These are two different things
• Nguyen Thai Binh: Yes they are two different things. While virtualenv supports older Python versions, venv is actually the preferred way (excluding other distributions like conda) to create an environment.

Answer 2

zsh: command not found: virtualenv

sudo is not a fix for this. Figuring out what is wrong with the current user's PATH, is the solution here...

However, Python3 comes with venv rather than needing to install anything else

python3 -m venv my-env
source my-env/bin/activate
