Encountering a clash in Npm dependencies

I have been involved in a Vue project where I utilized Vue Cli and integrated the Typescript plugin. However, I encountered multiple vulnerabilities that need to be addressed. When I executed npm audit fix, it failed to resolve the dependency conflict:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE could not resolve
...

The project is running on node version v14.17.4 and npm version 8.0.0.

Below is my package.json file. The majority of the project setup was done through Vue Cli, currently at version @vue/cli 4.5.14:

{
  "name": "uama.groundframework.frontend",
  "version": "0.1.0",
  ...
}

Answer №1

Your package.json contains a mix of dev dependencies with versions starting with both ~ and ^. This likely stems from some dev dependencies being installed with older versions of npm that defaulted to using ~, which is more conservative than ^. To start, update the 8 instances of ~ to ^, delete the node_modules directory, as well as the package-lock.json file (if present), and then run npm install again. I tried this out myself and while it didn't lower the number of vulnerabilities reported by npm audit, it did reduce the count of outdated packages, which is progress in the right direction.

Let's simplify things by focusing solely on the audit results for your production dependencies and disregarding any issues with your development dependencies for now. Running npm audit --only=prod reveals just 5 moderate issues. Executing 

npm audit --only=prod --force fix
will upgrade @capacitor/cli from version 2.x to 3.x. Keep in mind that this is a breaking change, so thorough testing is advised. However, if all goes well, you should be pleased to discover that npm audit --only=prod no longer reports any vulnerabilities.

At this juncture, you may choose to not focus too heavily on the other concerns flagged by npm audit. But if you decide to address them, here's a potential plan you could follow:

  • Conduct a manual review of all your dev dependencies to ensure there are no unnecessary or unused packages installed. Remove any unnecessary ones and consider uninstalling any nice-to-have but non-essential packages.
  • Use npm outdated to identify outdated dependencies that could be manually updated through breaking changes. Proceed with updating these dependencies.

Answer №2

If you encounter this issue, the solution is to downgrade the version recommended by npm.

For example:

npm ERR! code ERESOLVE npm ERR! ERESOLVE could not resolve npm ERR! npm ERR! While resolving: @vue/[email protected] npm ERR! Found: [email protected] npm ERR! node_modules/eslint npm ERR! peer eslint@">= 4.12.1" from [email protected] npm ERR! node_modules/babel-eslint npm ERR! dev babel-eslint@"^10.1.0" from the root project npm ERR! peer eslint@">=5.0.0" from [email protected] npm ERR! node_modules/vue-eslint-parser npm ERR! vue-eslint-parser@"^7.0.0" from [emailprotected] npm ERR! node_modules/eslint-plugin-vue npm ERR! dev eslint-plugin-vue@"^6.2.2" from the root project npm ERR! 1 more (the root project) npm ERR!

npm ERR! Could not resolve dependency:

npm ERR! peer eslint@">= 1.6.0 < 7.0.0" from @vue/cli-plugin- [emailprotected]

npm ERR! node_modules/@vue/cli-plugin-eslint npm ERR! dev @vue/cli-plugin-eslint@"^4.5.15" from the root project

In essence,

Dependency resolution error:

npm ERR! peer eslint@">= 1.6.0 < 7.0.0" from @vue/cli-plugin-

[emailprotected]

Therefore, update the eslint version to be between >= 1.6.0 and < 7.0.0 in the package.json file and then execute the command npm install. If any error related to dependency resolution arises, please refer to these guidelines.

We appreciate your cooperation.
