I attempted to uninstall then reinstall the global @vue/cli package, same issue.

Same with mac os

Exact same issue on macos 10.13.6,
both on Node 8.11.3 and 10.6.0.
Manually installing read-pkg (npm install -g read-pkg) doesn’t solve the issue either.

Same applies to Linux.

I didn't detect this because I have another global package that depends on read-pkg. :confused:

[Akryum]

As a workaround, npm i -g read-pkg or yarn global add read-pkg. Also make sure to clear your browser cache.

Same with Windows 10x64,Node v10.5.0

The workaround proposed by @Akryum fixed it for me!
I used npm install -g read-pkg
It hadn't worked previously, because I didn't clear my browser cache.
When doing that, it works!

[unclesan-pmer]

Because of my npm global path has a problem.
After modification, it works!
