I am getting the following error when trying to use yo @microsoft/sharepoint

Error @microsoft/sharepoint

This generator (@microsoft/sharepoint:app) requires yeoman-environment at least 3.0.0, current version is 2.10.3, try reinstalling latest version of 'yo' or use '--ignore-version-check' option

I have reinstalled the lastest version and can see that the current and wanted version matches when I use the command npm -g outdated.

I've got the same error, but in fact it seemed it came from the version of the generator-sharepoint that was not compatible.

try this :

npm uninstall -g @microsoft/generator-sharepoint

then install a previous version :

npm install -g @microsoft/[email protected]

I put here the version I have to be able to create spfx solution (because I had a looot of trouble finding stuff that work together) :

Yo --version > 3.1.1

node -v > 10.24.0 (avoid 12 at all cost)

tsc -v > 4.0.5

note : to check your version of generator :

npm ls -g --depth=0 @microsoft/generator-sharepoint

Hope it will help


Looks like your yeoman package is outdated. Try the following command to get the latest version:

npm install [email protected] -g


As of today, yeoman v4 is not compatible with the SPFx generator. this is why we install v3.

    Hi @denis-molodtsov, thank you for your help. I tried it but it just wouldn't work so I decided to just uninstall everything and reinstall it following the steps here docs.microsoft.com/en-us/sharepoint/dev/spfx/…

  • Good point. Perhaps, you also had other issues. For example, with the wrong node.js version Nov 2, 2021 at 13:13

check your version list---

  • npm ls -g --depth=0

try this :

  1. npm uninstall -g @microsoft/generator-sharepoint

then install a previous version :

  1. npm install -g @microsoft/[email protected]
