Hi,
Im trying to install Rasa on MacOs High Sierra 10.13.6. Im getting below error.
ERROR: Could not build wheels for alembic which use PEP 517 and cannot be installed directly.
I have python version 3.7.4
Please let me know if you need any information.
Thanks
Hi @Coder7771. Can you verify you followed the install steps? Also, can you share the text prior to the error output as well in a code block like below?
ERROR: Could not build wheels for alembic which use PEP 517 and cannot be installed directly.
Hi Ty,
Thank you for reply. Below are the steps I followed. I have Python version 3.7.4 version. Creating Virtual environment: python3 -m venv --system-site-packages ./venv source ./venv/bin/activate
Installing RASA: pip install rasa-x --extra-index-url https://pypi.rasa.com/simple
also tried
pip install rasa
But same error. Below is detailed error msgs again.

Hi @Coder7771. What happens if you don’t use the --system-site-packages flag?
python3 -m venv ./venv
source ./venv/bin/activate
pip install rasa
Hi Ty,
I have tried the steps you provided. It failed again. Error msgs changed now.

@Coder7771 What happens if you add the --no-cache-dir flag to the install command?
pip install --no-cache-dir rasa
I did that command now. Earlier issues are not coming now. Below are last few lines. It is saying about Tensorflow. Do you think installation completed?

@Coder7771 I am not sure. Does rasa --version work? If not, then I would try pip install --upgrade gast==0.2.2 and then try the installing again
Hi,
I’m also having the exact same problem. I tried what was recommended and it still does not work.
Thank you
Hi @stells. Can you share the command you ran, text prior to the error, and the error in a code block?
Hi @tyd ,
I am getting stuck on the same error. Please advise.
The first time I installed rasa for the Rasa Masterclass, it worked fine.
And now when I try install in again in a new directory for another simple chatbot it keeps failing with the same error message.
Failed to build ujson
ERROR: Could not build wheels for ujson which use PEP 517 and cannot be installed directly
And I also tried “–no-cache-dir” option, which also gave me an error,

@qmanpro537 What happens if you run pip install --upgrade wheel before trying again?
@tyd Same error even after I ran the upgrade

Try this command “CFLAGS=-stdlib=libc++ pip3 install rasa” . It worked and solution was from page where someone had similar issue error: command 'g++' failed with exit status 1 (during installation) · Issue #7 · src-d/tmsc · GitHub
Hi @asrinivas et @tyd
I have no idea how it worked, I just tried python3.7 -m pip install rasa before trying Ajay’s command. And surprisingly the usual way worked !! 
Thanks for looking into it!! I would like to have known the actual root cause, but hey I will take the dub ha ha.
I got this error too, but I noticed that there was also an error before this one, which said-
‘Microsoft Visual C++ 14.0 is required.’
This involved downloading Visual Studio Build Tools, easily available on the VS website. Once I did this, both errors disappeared.
i had the same problem, with python 3.7.6 but my problem came from “xcrun: error”, and it was solved using ``` xcode-select --install
In the meantime, I’ve written an unofficial guide that might help. Full description can be found on the forum here:
