Thanks for your answer, I’m following Part 4 of the book and I’ve already installed in my PC
• Visual Studio Code
• Node.JS LTS version
• Node.js Extension Pack (VS Code)
Problem arises when I open New Terminal, type cd \ and then npm -g install firebase-tool
The Firebase Tools aren’t installed as you can see in the previous message.
Thanks for any help!
Have you created a firebase project before?
I see that you already asked some questions about Firebase before.
If you’ve already installed firebase tools you don’t need to install them again.
Thanks for your message, here follow some comments:
1 – This is my first Project
2 – At the time I’ve asked some questions about Firebase I stopped working at the end of Part #3, since my main interest was the development of an associated ‘customized” hardware, which is running well since that time, perfectly validating Firebase’s RTDB operation and given instructions.
3 – Therefore, answering your question, this the first installation of said softwares.
4 – In the meantime I already uninstalled the softwares and carefully reinstalled them once again.
5 – Now I get:
