Command yarn tscw fails
Hi, I'm following this tutorial page https://duniter.org/fr/wiki/duniter/tutoriel-dev/chapitre-4-demarrage/ , and when I run yarn tsc
there is no problem, but when I run yarn tscw
I get the following output:
$ yarn tscw
yarn run v1.3.2
$ tsc -w
fs.js:1376
throw error;
^

info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
And I can't find util.js and fs.js files that are mentioned in the error. Any idea?
