I'm a beginner with the Ionic framework and I'm having a problem trying to install.
Recently I had to format my computer and now I can not install the framework again. When I run the npm install -g ionic command, the error that you can see in the image below appears.
I have Nodejs installed and would like to know if anyone there has ever had this problem and how can I fix it. Apparently it's a problem with the proxy, but I've tried what I knew and it did not work.
Thank you in advance for your attention. Thank you.
