I was trying to install flask-socketio on Ubuntu and in order to succeed, I read here on SO I should issue the following command: "sudo apt-get install python-dev libxml2-dev libxslt-dev".
After that I just can't find gunicorn, flask, etc.
How can I solve this?
Edit: I am not using VirtualEnv, so I install the modules using sudo apt-get install module name. Also, this is NOT duplicate, as the suggested answer speaks about VirtualEnvs.
ERROR on Console:
File "/usr/local/bin/flask", line 7, in <module>
from flask.cli import main
ModuleNotFoundError: No module named 'flask'
