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.

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

@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)

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

npm install -g yo generator-code mem-fs

This worked for me as well. However, I need to reinstall mem-fs globally each time I run yo code. Does anyone know why? It should already be installed, right?

The above alone didn't resolve the issue for me. The fix that I found was to:

  1. Uninstall all the relevant packages, nvm use v20.14.0, npm install -g yo generator-code mem-fs
  2. navigate to the install location for yeoman indicated in the error: code /path/to/node_modules/yeoman-generator
  3. npm install mem-fs
  4. npm run build to recompile dist with tsc.
  5. yo > choose generator.

Hilariously, there's no tsconfig.json in the project, so the build step resulted in me transpiling all TypeScript files in my home directory. Would recommend just copying theirs into the project root to avoid this issue.

This worked for me, thanks!
