Reproduction steps

Switch to the latest commits for the 5.2 branches in Cura (latest commit 20 October 2022) and CuraEngine (latest commit 19 October 2022). Go to the Cura directory and open conandata.yml. Find the section for "5.2.1", go to the requirements subsection. Change the entry "curaengine/5.2.1" to "curaengine/5.2.1@phedg1/vanilla".

Open command prompt admin and go to workspace directory. Run the following commands: powershell

conan editable remove curaengine/5.2.1@phedg1/vanilla conan remove "*" -f cd Cura rmdir venv cd ..

conan config install https://github.com/ultimaker/conan-config.git conan profile new default --detect --force

cd CuraEngine conan editable add . curaengine/5.2.1@phedg1/vanilla cd .. cd Cura conan install . cura/5.2.1@phedg1/vanilla --build=missing --update -o cura:devtools=True -g VirtualPythonEnv

PLEASE NOTE: Running conan remote remove cura will cause a different error when it tries to build cpython/3.10.4 requirement mpdecimal/2.50. Leaving in this remote lets the build get a lot further.

Actual results

I get the following error in the console:

Expected results

I expected Cura to build properly.

Full Log 2022-10-29 Vanilla.txt

Running Cura from source on Windows 10 on the 5.2 branch, with no requirements in editable mode, works perfectly. Adding curaengine as an editable package in conan causes it to fail. This is running completely vanilla Cura and CuraEngine, with the only change being to the conandata.yml. I only changed this build requirement so I could be extra sure it was using the local one in editable mode. It is also shown in the log that it is using the right version of Visual Studio (2022 Developer Command Prompt v17.2.5). I do not know how to get it to show the version of MSBuildDeps that is being used.

I have attached a full log of this issue. I am using Python version (3.10.4) and Conan version (1.53.0).

Hey @phedg1,

Thanks for the report. 👍 Issues related to the developer environment are outside of my comfort zone.

@jellespijker could you take a look, please? 🙏

@phedg1 can you try again? I synced the conan recipes between our cura and cura-ce artifactory remotes.

maybe first clean your conan cache

conan remove "*" -f

I have rerun my tests. Including the command "conan remote remove cura" gives the issue of missing mpdecimal.h #13622 . Removing that command from the steps gives the same error message about NoneType having no attribute replace.

I have updated visual studio community to 17.4, Conan to 1.54, moved my cura onto the latest commit in the main branch (10 November) but left curaengine in the 5.2 branch (19 October) (because the main branch is missing the 5.2.1 version in the conandata file). I removed the cura remote and got the same error about a missing mpdecimal.h.

Leaving in the cura remote gives the same error about NoneType.

I am clearing the Conan cache each time.
