RuntimeError: the sip module implements API v12.0 to v12.4 but the Arcus module requires API v12.6 #5930

Application version master branch

Platform Ubuntu 18.04

Reproduction steps I followed this steps exactly : https://github.com/Ultimaker/Cura/wiki/Running-Cura-from-Source-on-Ubuntu.I installed all the libraries in /usr/lib (so I had to be super user to do it)

Actual results

I saw issue #5683 but when I try purge sip, I got

Hi,

Can you check your sip version?


Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:57:15) [MSC v.1915 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sip
>>> sip.SIP_VERSION_STR
'4.19.8'
>>> sip.__file__
'C:\\workspace\\installations\\python\\3.7.1\\lib\\site-packages\\sip.pyd'
>>>```
francoisbrassart commented 5 years ago

Hi,

>>> import sip
>>> sip.SIP_VERSION_STR
'4.19.8'
>>> sip.__file__
'/usr/local/lib/python3.6/dist-packages/sip.so'
LipuFei commented 5 years ago

@francoisbrassart what if you run import Arcus in that same console you run import sip + sip.__file__? Do you get the same error?

francoisbrassart commented 5 years ago

Yes, same error...

>>> import sip
>>> sip.__file__
'/usr/local/lib/python3.6/dist-packages/sip.so'
>>> import Arcus
Traceback (most recent call last):

pkuiper-ultimaker commented 5 years ago

OK. It seems that libArcus might have been compiled against a different python version.

Can you rebuild libArcus (please first delete the CMake cache) and carefully check the CMake output. Make sure it finds the correct python path (/usr/local/lib/python3.6/ in your case).

Looks like it found the good path for Python

francoisbrassart commented 5 years ago

Ok maybe I did something wrong, now I don't have this error anymore but the 2nd one

LipuFei commented 5 years ago

The sip executable it's using doesn't seem correct:

-- Found SIP: /usr/bin/sip (found version "4.19.8")

Your sip shown from the python console comes from /usr/local but this one comes from /usr. Can you check if you have /usr/local/bin/sip?

pkuiper-ultimaker commented 5 years ago

The 'UM' module is from Uranium. Did you add the Uranium path to env? This instruction:

$ export PYTHONPATH=[URANIUM_PATH]:${PYTHONPATH}

francoisbrassart commented 5 years ago

@pkuiper-ultimaker My bad, when I export this path, I'm going back to the initial error

pkuiper-ultimaker commented 5 years ago

OK. Then now run "cmake-gui" and point to the libArcus build folder. Force Cmake to find SIP in '/usr/local/lib/python3.6/dist-packages/sip.so' not in '/usr/bin'. Configure, generate and build again. Check the CMake output to see if the correct sip executable is found,

francoisbrassart commented 5 years ago

I did what you said : in cmake-gui, I linked the SIP EXECUTABLE to the value "/usr/local/lib/python3.6/dist-packages/sip.so".

When I go back in the build folder of libArcus, I have this error 

sudo make

Try

sudo pip3 uninstall sip

Uninstalling sip-4.19.8:
  /usr/local/lib/python3.6/dist-packages/sip-4.19.8.dist-info/INSTALLER
  /usr/local/lib/python3.6/dist-packages/sip-4.19.8.dist-info/METADATA

  /usr/local/lib/python3.6/dist-packages/sip-4.19.8.dist-info/WHEEL
  /usr/local/lib/python3.6/dist-packages/sip.so
Proceed (y/n)? y
  Successfully uninstalled sip-4.19.8

I needed to include sudo because without it I got a permission error.

Now I get this result and can start Cura
