With the release of version 2.0.0-beta.205 we introduced peer dependencies. Most packages require the installation of peer dependencies.
Why peer dependencies
In the past it has happened that users installed ProseMirror or Yjs packages to develope their own extensions, which had a different version than the ones included in Tiptap. This has caused version clashes.
How to install
NPM 7 or higher
If you are using NPM 7 or higher, you can ignore the following notes. NPM installs peer dependencies automatically and no further action is required.
Yarn, pNPM, npm 6 or less
