Fix the upstream dependency conflict installing NPM packages
The message “Fix the upstream dependency conflict installing NPM packages” appears quite frequently in NPM Package Manager. When installing NPM packages globally on a Mac, you will frequently run across this issue.
This blog provides a list of various solutions to the issue that you are experiencing.
Reason
Upstream dependency conflicts can be very challenging to resolve. Because one dependency can be linked to another dependency that uses a different version, this can result in version conflicts.
The conflict described can be resolved in either of two different ways. The first and most straightforward option is to move the import of library G ahead of the import of library Y within the POM file for X.
Nevertheless, an approach that is more organized would be to include the most recent version of Z (2.0) as a direct dependency of X within the POM file for X.
If library Z supports backward compatibility, the second option might work, but only with a little bit of luck (as library Y uses v1.0 of Z). In this situation, testing is necessary in order to boost reliability.
Even if there are version conflicts, it does not necessarily mean that your project will crash. Typically, there will be version conflicts if you use a large number of libraries.
However, we need to take precautions to ensure that the version of the library we use does not cause our project to crash.
