In recent years, with the widespread application of Node.js around the world, more and more developers have begun to use the framework in their projects. However, due to frequent updates of Node.js, many people have some problems when upgrading or uninstalling the version. Sometimes, even if you have uninstalled Node.js, there are still some files or configurations left behind, which often causes trouble for developers. This article will delve into the problem of unclean uninstallation of Node.js and provide some solutions.

  1. Understand the installation path of the Node.js file

First of all, it is very important to understand the installation path where the Node.js file is located. For most operating systems, the installation path of Node.js is set in environment variables. Therefore, to find the path, you can open the command line and enter the following command:

echo %PATH%

This will output all paths in the current operating system environment variables. Find the folder containing the words "node.exe" or "npm". This is the path where the Node.js you installed is located.

  1. Uninstall Node.js

If you are using a Windows operating system, you can uninstall Node.js through the control panel, or you can delete the Node.js program folder directly. However, this approach may not completely remove Node.js, leaving a lot of cluttered files and configurations behind. To ensure a complete uninstall of Node.js, you can try the following:

  • Uninstall Node.js in the Control Panel.
  • Delete the Node.js installation folder.
  • Delete the following folder:
C:Users{yourUsername}AppDataLocal
pm
C:Users{yourUsername}AppDataRoaming
pm
C:Users{yourUsername}AppDataRoaming
pm-cache
  • Delete the following directory:
%USERPROFILE%AppDataRoaming
pm-cache
%USERPROFILE%AppDataRoaming
pm
%USERPROFILE%.npmrc

Note: Before deleting these directories, please make sure the backup is important Node.js project.

  1. Check environment variables

Another important aspect is to check that your environment variables are set correctly. You can open the environment variable editor through the control panel or other tools (such as Rapid Environment Editor) to see if there is still a path pointing to the Node.js file. If present, delete it.

  1. Use the Node.js Uninstall Tool

If you still feel that you cannot completely clear Node.js, or you may have deleted some system files, you may consider using a dedicated Node.js uninstall tool. These tools can help you quickly detect and remove residual Node.js files and configuration. The following are some recommended tools:

  • Revo Uninstaller
  • IObit Uninstaller
  • Geek Uninstaller
  1. Summary

When uninstalling Node.js, make sure to completely delete all files and configuration of the framework. You can delete files manually, edit environment variables, or use the Node.js uninstall tool. While manual deletion may take some time, it's a nuanced approach that can help you avoid problems caused by leftover files. Using the Node.js uninstall tool is a faster method, but may not detect all files. Ultimately, which method you choose depends on your personal preferences and needs.
