Subject: [PATCH] map error from cmd.spawn in npm::install

If the tool (yarn) does not exists, spawn() raise an error, but the error message is just like a `No such file or directory`. So it is hard to understand which application/file/directory has a problem. This commit maps the error to expose the problem is around yarn.
