environment variable.

To configure your current shell, run:
source /home/b1ue/wdir/dec/vlc.js/vlc/contrib/bin/.cargo/env
. /home/b1ue/wdir/dec/vlc.js/vlc/contrib/bin/.cargo/env && RUSTUP_HOME=/home/b1ue/wdir/dec/vlc.js/vlc/contrib/bin/.rustup CARGO_HOME=/home/b1ue/wdir/dec/vlc.js/vlc/contrib/bin/.cargo rustup default 1.47.0
/bin/sh: /home/b1ue/wdir/dec/vlc.js/vlc/contrib/bin/.cargo/env: No such file or directory
