I went to install nodejs and npm on Debian9 like this with the root account because npm is not included in the legacy debian package :
curl -sL https://deb.nodesource.com/setup_8.x | bash -
.../...
## Run `apt-get install nodejs` (as root) to install Node.js v8.x and npm
:~#
:~# apt-get install -y nodejs
Now I would like to install some module with npm or to do the update of npm and I've got this error message
:~# npm cache clean -f
npm WARN using --force I sure hope you know what you are doing.
:~# npm install -g npm
npm ERR! code ERR_INVALID_OPT_VALUE
