Steps to reproduce

1. vue create myproj
2. cd myproj
3. vue upgrade

What is expected?

Upgrade should work.

What is actually happening?

Even after following the instructions and globally installing @vue/cli-upgrade, I get the same message instructing me to install the package.

I have the same problem. No matter how you try, it will always told you to install @vue/cli-upgrade instead of upgrading.

And news on this? This is pretty frustrating....

The upgrde functionality was added unofficially to test it out. It's not a documented feature yet.

We will revamp it a bit, hopefully within March.

[iuliuscaesar92]

The same story. Nothing changed in that time?

[lpj145]

not a solution ?

This still does not work. Vue-cli version 3.11.0, OS X. I get

Command vue upgrade requires a global addon to be installed.  
Please run npm install -g @vue/cli-upgrade and try again.

@vue/cli-upgrade is installed and also at 3.11.0.

I have the same issue. I am using vue-cli v3.11.0 on Windows 10 (1903). Vue has been installed globally with vue install -g @vue/cli and I am running many browsers other than Edge, which is the only one detected.

I still don't know what stops vue upgrade from working properly in v3.
But anyway, in Vue CLI v3, it does nothing more than invoking npm update or yarn upgrade underlyingly for @vue/cli-service & @vue/cli-plugin-* packages. So I recommend you to use these commands instead.
BTW, yarn upgrade-interactive has a nice user interface.
