How do I resolve this ?

回答1:

py3compile: not found

The py3compile command is part of python3-minimal package which seems to be broken.

To fix the issue, try the following:

• Correct a system with broken dependencies in place by:

  sudo apt-get  -f install 

• Reconfigure all unpacked, but unconfigured packages by:

  sudo dpkg --configure -a 

• If above won't help, try reinstalling python3-minimal package by:

  sudo apt install -f --reinstall python3-minimal 

  Alternatively run:

  apt-get download python3-minimal sudo dpkg -i *python3*.deb sudo apt install -f 

  Or download the .pkg file from kernel.org and install from the file by:

  sudo dpkg -i python3-minimal_*.deb 

Then make sure that py3compile and py3clean commands are runnable and are accessible from your PATH variable.

回答2:

Try this:

First remove packages not more needed:

sudo apt-get autoremove 

Clears out the local repository of retrieved package files

sudo apt-get autoclean 

Remove the packages(mysql-client is not installed):

sudo apt-get remove mysql-server mysql-common 

回答3:

Despite py3compile and py3clean being present in /usr/bin/, my Lubunutu 16.10 shell (tcsh) kept complaining that py3compile was not there. After hours of frustration, I discovered that the first line in pycompile was:

! /usr/bin/env python

or something like that, which referred to Python2.7 on my system. Changing that to point to Python 3 with:

! /usr/local/bin/python3

suddenly made py3compile visible!

Turns out that the shell said py3compile did not exist even when it was in its path or was directly executed with "/usr/bin/py3compile" when py3compile referred to Python2.7. The shell did not even complain about the Python version or anything, it just claimed py3compile itself did not exist!

I got into this mess because I wanted to remove and reinstall Python 3.5, upon doing which I discovered that there is still a Python 3, which I then discovered comes from a python-minimal, which I tried to remove and reinstall. The python-minimal would not reinstall, even after I tried every thing I could find on the net and every package manager. They all would complain about py3compile missing. Now I discovered this fix for py3compile.
