While installing meson using pip3 install --user meson, due to python path issues, build.ninja can't be located by ninja. meson generates ninja files fine, but then when you run ninja, it is unable to find meson's build.ninja python module due to path issues. It gives the following error on ninja -C build install: ninja: Entering directory `build' ninja: error: loading 'build.ninja': No such file or directory After uninstalling meson using pip3 and installing it again using pip without --user argument solved the issue.
