I tried installing code-generator to create my own syntax highlighting in vscode. However, when I tried running code with yo code, this happened :

yo code
/usr/local/lib/node_modules/yo/node_modules/yeoman-environment/lib/resolver.js:70
    filePatterns: lookups.flatMap(prefix => [`${prefix}/*/index.ts`, `${prefix}/*/index.js`, `${prefix}/*/index.cjs`, `${prefix}/*/index.mjs`]),
                          ^

TypeError: lookups.flatMap is not a function
    at Environment.resolver.lookup (/usr/local/lib/node_modules/yo/node_modules/yeoman-environment/lib/resolver.js:70:27)
    at init (/usr/local/lib/node_modules/yo/lib/cli.js:130:7)

    at startup (internal/bootstrap/node.js:283:19)
    at bootstrapNodeJSCore (internal/bootstrap/node.js:623:3)

Do you have any idea how I can fix it ?

Try updating NPM. That fixed it for me anyway.
