Answer 2

Package name 1 and package name 2 are the same package, but the versions are different, and the version of package name 1 is higher than that of package name 2. If there is ` in front of the configuration, what you encountered will happen.
For example vue:''2.14'
If vue has a higher version than 2.1.4, when npm install, vue will be updated to the latest existing version!
