Sometimes we need to test if our code also works with
PyPy implementation of Python. Assuming you
have already installed it in your system, first find out where it is
installed:
1
2
|
which pypy
/usr/local/bin/pypy
|
then you need mkvirtualenv to create a virtual environment that will
use this runtime:
1

3
4
5
6

|
mkvirtualenv -p /usr/local/bin/pypy pypy-test
Running virtualenv with interpreter /usr/local/bin/pypy
New pypy executable in pypy-test/bin/pypy
Installing setuptools, pip, wheel...done.

That’s it! You can now use this virtual environment to run your Python
application using PyPy environment.
