As the title says, I keep on having that error and I don't know how to solve it.
The error, as the title says is
virtualenv: error: the following arguments are required: dest
The command I entered was
virtualenv
I am running this on a MAC and on python
When you ask the question, try to also explain what are you trying to do, and not only the error you get :)
If I'm guessing correctly, you're trying to create a new virtual environment. When executing the virtualenv command you need to specify a name (dest) for it, so that it will create the virtual environment under that folder.
Your command should look like this:
virtualenv venv
where venv is the name of the folder that will get created.
See some more information here: https://programwithus.com/learn-to-code/Pip-and-virtualenv-on-Mac/
path/virtualenv pythonfinance
this will create a virtual environment in the folder pythonfinance.
