How to install a previous exact version of a NPM package?

 

To install a previous exact version of an npm package, you can use the npm install command with the @ symbol followed by the package name and the desired version number. Here's how you can do it with an example:

Let's say you want to install version 2.3.1 of the "example-package" npm package.

bash

npm install example-package@2.3.1

Replace "example-package" with the actual name of the package you want to install, and replace "2.3.1" with the version number you want to install. Running this command will install the specified version of the package in your project.

Keep in mind that specifying an exact version number like this is useful when you want to ensure that your project uses a specific version of a package. However, it's important to note that this approach can lead to potential compatibility issues in the future if you're not careful when upgrading packages. If you want to follow best practices for dependency management, consider using a package.json file and specifying version ranges or using npm's "semver" (semantic versioning) features to define acceptable version ranges for your dependencies.
