When I installed Yarn on Debian Stretch I haven't problemsn, but when I launch yarn init I obtain a error:
ERROR: [Errno 2] No such file or directory: 'init'
Even though when doing
so How Install Yarn properly
The solution I obtained was (and according to this tuto):
First download the repositoriy key for verify identity:
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
After add the url repository to file sources.list.d
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
And if you had installed Yarn before you have to force the installation, in this way:
apt-get -o Dpkg::Options::="--force-overwrite" install yarn
And with this it should be enough.
