Did you check your internet connection? Appears to be an issue with you not having internet or a proxy blocking access to the internet.

I had the same issue installing with windows but I just cloned the project with git clone <repo url> projectname.

[Cheizr]

Fixed, worked for me:

• Uninstall the global module create-react-app
• Clear npm cache
• Reinstall create-react-app

Linking dependecies last like 40 min, but maybe it's only my hdd

[EthanC]

Still an issue for me unfortunately, even after following those steps 😕

[NoiseEee]

This should not be marked closed, Yarn still fails.

[tzarebczan]

Could be related to this: #4588 (comment)

[massimopibiri]

"npm cache clean --force" solved my problem

[daliadefelipee]

Hi @NoiseEee. I think this issue was closed since the root of the problem was the antivirus software running as @tzarebczan stated in his link.

[IhsanMujdeci]

npm uninstall -g create-react-app
npm uninstall -g yarn
npm cache clean --force
npm install -g create-react-app
create-react-app cool-projecy-name

Not sure if the uninstall of create-react-app and cache clean is needed but this is what worked for me.
