Manually delete Node.js

Node.js is a popular server-side runtime environment that allows JavaScript to run on the server side, enriching the possibilities of web development. Installation and upgrade of Node.js often require a specific installer, but sometimes manual removal of Node.js is necessary, which may be due to the following reasons:

1. Error or incomplete upgrade of Node.js Success;
2. Node.js is installed but you no longer need it;
3. You want to install a different version of Node.js and need to delete the old version.

No matter what the reason is, this article will guide you how to delete Node.js manually.

Step 1: Check the Node.js installation directory

First, you need to find the path where Node.js is installed. This can be achieved by entering the following command at the command line:

$ where node

This command will display the path to the Node.js program file as follows:

C:Program Files
odejs
ode.exe
C:Program Files (x86)
odejs
ode.exe

Typically, it is located at "C :Program Files
odejs" or "C:Program Files (x86)
odejs" is the installation directory of Node.js.

Step 2: Delete the Node.js installation directory

After finding the Node.js installation directory, you can directly delete the directory and its subdirectories to uninstall Node.js. Please note that this will not only delete the Node.js program itself, but also all Node.js packages under that version.

If you just want to upgrade Node.js, just delete everything in the old version directory instead of deleting the entire folder.

Step 3: Check environment variables

After deleting the Node.js installation directory, you need to check the environment variables to ensure that Node.js has been completely deleted. You can press the Windows R key to open the run window, enter "cmd" and press the Enter key to open the command line window, enter the following command in it:

$ node -v

If you see a "command not found" error , then Node.js has been completely removed. Otherwise, you need to manually delete the Node.js path in the environment variables.

Step 4: Delete Node.js related environment variables

In order to completely delete Node.js, you also need to check the environment variables to find any paths pointing to Node.js. Press the Windows R key to open the run window, enter "%windir%System32undll32.exe sysdm.cpl,EditEnvironmentVariables", and press the Enter key to open the environment variable editor. In the editor window, find the System Variables section and click on the following variables:

1. NODE_EXE
2. NODE_HOME
3. NODE_PATH

When these variables are clicked, their values ​​are displayed. If these values ​​point to a previously deleted Node.js installation directory, click the Edit button and change the values ​​to the correct ones or delete them.

Step 5: Delete npm

When deleting Node.js, you should also delete npm. To remove npm, follow these steps:

1. Enter the following command at the command line: npm ls -g --depth=0 to view globally installed npm packages.
2. For each package, use the following command to uninstall it: npm uninstall -g package name.
3. Delete npm cache, the command is as follows: npm cache clean --force.

After completing the above operations, you have completely deleted Node.js and npm.

Conclusion

The process of manually deleting Node.js is not complicated. You only need to find its installation directory and delete it. Additionally, you need to check the environment variables and remove any paths pointing to Node.js.
