I get an error when trying to get into the python shell by using repl

mpfs [/]> repl
Traceback (most recent call last):

That directory looks weird, how did you install it?

bartvollebregt commented 5 years ago

I installed it with sudo pip install mpfshell But /usr/local/bin/mpfshell isn't such a weird location is it?

Isn't build/bdist.linux-x86_64/egg/mp/mpfshell.py the location on the micro controller?

skorokithakis commented 5 years ago

No, that code runs on the PC, not the microcontroller, that's why I'm confused. I don't think it should be under build/. Are you running it from a place where you have a checkout of mpfshell?

elishaROBINSON commented 5 years ago

facing the same issue im running mpfshell in ubuntu 18.04 as root im trying to connect to a esp8266 with micropython on it should i reinstall micropython on the esp8266

bartvollebregt commented 5 years ago

Hmmm I installed it using:

git clone https://github.com/wendlers/mpfshell .
sudo pip install -r requirements.txt
sudo python setup.py install

This is my install location:

➜  ~ which mpfshell
/usr/local/bin/mpfshell

I am running disco dingo:

Hmm, I can't reproduce this (lots of intermediate output elided to avoid spam):

Can you try with python2 in an non-virtual env?

I think I'm running into the same issue (on Ubuntu 19.10):

To follow up on myself (with apologies): when python3 is the default, the REPL in mpfshell works. This can be accomplished with sudo update-alternatives --install /usr/bin/python python ... (I switched from the default 2.7.17 to 3.7.5).
