为什么有时我的Nodejs会自动升级到最新版本的Nodejs？

Question

I have a previous version of node installed but after few days it gets automatically updated to the latest version. I do not want it to upgrade itself to a newer version.

Answer 1

You need to specify the exact node version in your package.json file.

A bit of background, from the NPM documentation :

It's important to communicate the extent of changes in a new release of code, because sometimes updates can break code that a package needs (called dependencies).Semantic versioning (semver) is a standard that was designed to solve this problem.

1. From your terminal, type node --version ; you will get a number formatted as XXX
2. Open your package.json file and remove any ~ or ^ signs from the node version you want to use so that it won't update to any minor or batch changes.
3. enter npm install in your terminal again and you are done.
