npm command create-react-app failled

Question

I am trying to test reactjs on my computer (mbp pro 2017) running OsX sierra 10.12.6. I have followed the Facebook tutorial:

1. Make sure you have a recent version of Node.js installed. (done)
2. Follow the installation instructions to create a new project. https://facebook.github.io/react/docs/installation.html#creating-a-new-application

But i have a problem on this second step !

• I am not behind a proxy.
• my network is ok.
• The repository is set to registry.npmjs.org
• i can read the url : https://registry.npmjs.org/create-react-app
• But this domain is not found even on external DNS wsg.intra.corp.grp

I'am stuck, any help will be nice !

$ npm install -g create-react-app

npm ERR! errno ENOTFOUND

Solution 1

You seem to be behind a corporate proxy, as wsg.intra.corp.grp:8080 is mentioned in the logs.

You need to configure the proxy like shown in this guide.

Hope this helps!

Solution 2

I solved this issue just by, go to settings>Network and Internet>Proxy and then off Automatically detect settings under Automatic proxy setup on Windows. And then the installation worked fine.

Solution 3

Run below commands on your command prompt. Make sure node and npm are installed.

npm config rm proxy

npm config rm https-proxy

open this link in your browser: https://registry.npmjs.org/

Run below command to set registry.

npm config set registry https://registry.npmjs.org/

Hope its help : )
