Operating system (windows, osx, ...): linux

Issue: pip3 install does not work

Error (including full traceback):

$ pip3 install rasa
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Defaulting to user installation because normal site-packages is not writeable

Thanks for the issue, @tttthomasssss will get back to you about it soon!

You may find help in the docs and the forum, too 🤗

@jmyounker there is currently not python 3.8 support in a released version of rasa open source; As you can see in the Installation Instructions Rasa Open Source requires Python 3.6 or 3.7. This will be available in the next major or minor (not patch) release.

[jmyounker]

Any estimate as to when 1.11 gets released?

[erohmensing]

We're currently working towards a 2.0 release, alphas will be out very soon but it’ll be late this summer before it’s out!

Dear all,

any news on this one? Rasa Open Source 2.0 is out and supports python 3.8.

[erohmensing]

@papadako what news are you looking for? Yes, 2.0 does support python 3.8.

@papadako what news are you looking for? Yes, 2.0 does support python 3.8.

@erohmensing hi, somehow I thought this was an issue about the rasaX, which still does not support python 3.8
