hello! as we are working in mixed py2 and py3 env, is it possible to tell repl to mixed with different ipython versions ?

ipython_requirements: ['ipython~=5.8.0; python_version<3']

?

Do you mean “If Py2, use 5.8.0, but if Py3, use the newest possible”?

Yes

Try this:

ipython_requirements: ['ipython==5.8.0; python_version<3', 'ipython==6.2.0; python_version>=3',]

Does that work?

@hundreds-father-404 with the suggested config: For py2:

ImportError: No module named IPython

For py3, it works but resolve ipython to

7.11.1

(not the one specified, so I guess it is the default value or latest) ps. I am not hijacking leozc’s thread, I work with him

ipython_requirements

is in the

repl.py

section?

Hey @calm-artist-46894 @plain-sundown-25537, try this. I got it working locally:

[repl.py]
ipython_requirements: [
    "ipython==5.8.0 ; python_version<'3'",
    "ipython==7.11.1 ; python_version>='3'",
  ]

Also run

./pants clean-all

the first time. We forgot to set

fingerprint=True

so the cache is not invalidated 🤦‍♂️ I’ll put up a fix today for this. (Also, it’s not an issue with V2 🎉)
