When you try to install packages, adonis/npm install works at the second try if I have chance. I don’t know why ?
Could you elaborate? The question is unclear.
Share for example the command line you used to install which package, along with the error messages you got.
Make sure to stop the server. Sometimes it failed to install some packages when the application is running. It will work fine if you shut the application. Not sure about your case but I wanted to mention this.
