From 76a5861f3ef0950d9b57e54668c9059ed7bddd89 Mon Sep 17 00:00:00 2001 From: Vedant Paranjape Date: Wed, 31 Mar 2021 12:46:00 +0530 Subject: Add alternative meson install command 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. Add a troubleshooting section to the readme to describe this issue and suggest possible solutions.
