ModuleNotFoundError: No module named 'distutils'
-
[ Test Plan ]
install python3-pycallgraph.
As a basic test, execute "pycallgraph --help"
If the package is not fixed,it will fail with the above error.
With the fixed package, it will display the help menu.
As a more complete test:
copy the attached basic.py and use the command:
pycallgraph graphviz basic.py
It will create two png files "basic.png" and "pycallgraph.png".
-
[ Where problems could occur ]
The 'distutils' module is not available in Python3.12. 'distutils' was used
previously to find the executable and was also used to get the path of the
python lib. Now, its being replaced with 'shutil' and using 'which' to find the
executable. And, 'sysconfig' is used to get the path of the python lib.
In the worst case, if 'which' or 'sysconfig' fails to find the path then the
user will still see pycallgraph is failing but with a different error message.
-
[ Other Info ]
- It has been fixed in Debian and so Oracular is also fixed now.
+ 1. It has been fixed in Debian and so Oracular is also fixed now.
+
+ 2. In Focal, the patch had to be modified to hardcode the path as I am unable
to get the path '/usr/lib/python3/dist-packages' from any of ths syconfig
opions. All the sysconfig variables and paths can be seen with the command
'python3 -m sysconfig' and there is no way to generate the required path from
sysconfig.
+ And, in Focal pycallgraph will be installed in that path, if 'tracer.py' does
not get the correct path then the generated 'pycallgraph.png' will not be same
as Jammy or Noble or Oracular with the same test file 'basic.py'.
