I am also facing the same issue

[mshima]

C:\Users\KHC1SZH\chenkai\Projects\vscodePluginsDemo>node --version v14.17.2

C:\Users\KHC1SZH\chenkai\Projects\vscodePluginsDemo>npm --version 6.14.13

yo@5 requires node 18 and npm should be at least v7, latest is recommended.

[atulbhatt-system32]

I tried with node -v (21.5.0) and npm -v (10.2.4) but what worked for me was downgrading yo to version 4.3.1

[atulbhatt-system32]

@mshima is node 18 the minimum requirement or greater also works for yo@5 as in my case it didn't. node -v (21.5.0) and npm -v (10.2.4)

[mshima]

yo must be installed with newer npm (must support peer dependencies).

npm install -g npm@latest
npm uninstall -g yo generator-code
npm install -g yo generator-code
npm uninstall yo generator-code # make sure it’s not installed locally
yo code

Playing with the npm and node versions didn't work for me.

It seems that this issue still persists, but what allowed me to continue was running:

npm install -g yo generator-code mem-fs
yo code
