• Summary

Creating new projects with the CLI currently errors, because there is a dependency mismatch between the typescript version the project provides and the typescript version that typedoc requires. It is probably best to upgrade typedoc to the newest version.

• Other information (e.g. detailed explanation, stack traces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)
