navigate to the apps folder or wherever you plan to install Keystone cd apps/
install keystone yarn create keystone-app
navigate back to the root directory cd ../
add .keystone/** to turbo.json Pipeline:
"build": {"dependsOn": [ "^build" ], "outputs": [ ".next/**", ".keystone/admin/.next/**" ]}}
build project from root directory cd ../ && yarn build
Observe error message from inside ./keystone

Answer 1

I have been able to replicate this, and it looks to be an issue with the next version that npx create-turbo#latest installs and is pinned to. Running create-turbo installs next 12.0.8 and is pinned to that version. Keystone requires at least version 12.1.0.
When I changed my ./apps/web/package.json to:
"dependencies": {
"next": "^12.1.0",
"react": "17.0.2",
"react-dom": "17.0.2",
"ui": "*"
},
The error no longer occurred.
