I have already installed pipenv using,
pip install pipenv on the directory which was installed successfully. But

pipenv install Django==2.1 does not seem to work. In fact, no command is getting executed using pipenv.

pip install pipenv

Anything on Google Colab suggestions would be very helpful!

pip is a shell command. I assume Google Colab has made pip available as a special command(*) (without the % syntax), but that doesn't mean any other shell command works as such. That is why you get a SyntaxError: it is not recognised as normal Python syntax.

You can work around it by using !pipenv install 'Django==2.1' (the single quotes may not be necessary, but the exclamation work is).

I doubt, however, that you really need a virtual environment in the first place. This is not on your regular machine, where you may want to keep dependencies apart. Instead, just start a new notebook for a new project, and install Django as normal: pip install Django. I wouldn't bother with pipenv and virtual environments inside notebooks. There doesn't seem to be any use for it.

(*) Try, for example, pip?, and note the help lists its usage with the %pip syntax. I assume that, if it's not ambiguous, Colab will use %pip when called as pip. The same works for, for example, ls instead of %ls.
