This error message tells you that you used an unsupported URL type "workspace:" in your npm command.
In npm, the "workspace:" prefix is used to indicate a package in the current workspace.
Usually, when using the npm command to install a package, you need to provide the name of the package or the address where the package was published (for example, npm install express or npm install https://github.com/expressjs/express).
If you get this error when using the "workspace:" prefix, you're probably trying to install a package that doesn't exist in your current workspace. You need to check whether the package name is wrong or whether you are running in the correct workspace directory
