• Install fail Error: Unsupported URL Type “workspace:“: workspace

 Background: Trying to initialize npm i failed, and the error message was:
Install fail! Error: Unsupported URL Type "workspace:": workspace:*
Reason: Check whether [workspace:] appears in the project dependency version in package.json. If I use npm i to install, it says "Unsupported URL type "workspace:": workspace:". If you use yarn to install, it's ok!

Solution:
1. Install yarn
npm install -g yarn
2. Install a certain package name
yarn add @type-challenges/utils
The installation is successful! 
3. Install all
yarn
install successfully!
