When running node ./setup_cpp.js --cppcheck true (on its own), it works.

I test it a bit:

• node ./setup_cpp.js --cppcheck true: Works
• node ./setup_cpp.js --cppcheck true --ccache true: Works
• node ./setup_cpp.js --cppcheck true --cmake true: Works
• node ./setup_cpp.js --cppcheck true --vcpkg true: Works
• node ./setup_cpp.js --cppcheck true --doxygen true: Works
• node ./setup_cpp.js --cppcheck true --gcovr true: Fails
• node ./setup_cpp.js --compiler llvm --task true: Works

gcovr gets installed via pip and installs pygments. When installing cppcheck, pygments seems to be installed via pacman.

Installing python-pygments before running setup_cpp.js seems to fix it ?, but idk why. (Maybe it didn't need to be reinstalled when installing cppcheck and no conflicts happen)

RUN pacman -S --noconfirm python-pygments
RUN node ./setup_cpp.js --cppcheck true --gcovr true

RUN pacman -S --noconfirm python-pygments
RUN node ./setup_cpp.js --compiler llvm --cmake true --ninja true --cppcheck true --ccache true --vcpkg true --doxygen true --gcovr true --task true
