Failed to set up virtualenv for mycroft, exiting setup.
Raspbian Install.
Also interesting to note that "Processing triggers for sgml-base" is listed twice. Odd?
Seems to be a work-around here. But this is still a bug.

on Raspbian, this could be added to the install script:
Git is already installed. So download the git repo into a 'cpython' subdirectory inside the 'mycroft-core' directory via git:
git clone https://github.com/python/cpython.git
And build and compile it:
cd cpython
./configure
make -j 4
sudo make altinstall
cd ..
If git is not installed, (since this script runs on all Linux), consider this before git clone
:
Install from source:
https://git-scm.com/book/en/v2/Getting-Started-Installing-Git
New problem:
After compiling and installing cpython
, The start-mycroft.sh
script still fails, but continues after failing:

start-mycroft.sh: Mycroft command/service launcher
usage: start-mycroft.sh [COMMAND] [restart] [params]
Services COMMANDs:
all runs core services: bus, audio, skills, voice
debug runs core services, then starts the CLI
audio the audio playback service
bus the messagebus service
skills the skill service
voice voice capture service
enclosure mark_1 enclosure service
Tool COMMANDs:
cli the Command Line Interface
unittest run mycroft-core unit tests (requires pytest)
skillstest run the skill autotests for all skills (requires pytest)
Util COMMANDs:
audiotest attempt simple audio validation
audioaccuracytest more complex audio validation
sdkdoc generate sdk documentation
Options:
restart (optional) Force the service to restart if running
Examples:
start-mycroft.sh all
start-mycroft.sh all restart
start-mycroft.sh cli
start-mycroft.sh unittest
It acts like it's installed, after failing.
When attempting to use ./start-mycroft.sh debug
, it fails with multiple errors:

Guessing you're not using picroft, which just works.
Guessing you're not using picroft, which just works.
Correct. Because I like doing other things with my Rpi in a GUI environment too, and Picroft failed to run properly and didn't detect a basic USB microphone. Can't report bugs without a GUI
This is a really weird issue. Seems like the python environment on your device isn't quite working or something? _ctypes is included in the local python standard library which is used to create the mycroft virtualenv.
Can you try to delete the .venv
folder in the mycroft-core directory rm -rf .venv
and then rerun the dev_setup.sh script?
Hi, since there's been no communication on this issue for 4 months I'm going to close it. If you're still experiencing this problem feel free to reopen the issue.
I found answer here, Zachary Ware's answer. I used yum install libffi-dev
to fix it.

Yes that worked for me, I made sure these packages are installed on my Centos 7:
sudo yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel libffi-dev gcc gcc-c++ zlib libffi-devel
Then reinstalled my python 3.8.1:
wget http://python.org/ftp/python/3.6.8/Python-3.6.8.tar.xz
tar xf Python-3.6.8.tar.xz
cd Python-3.6.8
./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
Then I was finally able to install docker-compose:
pip3.8 install docker-compose
Thanks @grossshen
