How to uninstall nodejs on mac

With the popularity of JavaScript and the development of web development, Node.js, as a running environment for JavaScript, has also attracted much attention in the technical field. However, when developing projects using Node.js, sometimes you need to uninstall Node.js, and many people may encounter problems at this time. In Mac systems, uninstalling Node.js is not as simple as Windows systems and requires some steps and operations. Next, let’s take a look at how to uninstall Node.js on Mac.

Why do you need to uninstall Node.js?

During the process of using Node.js, if the installation fails, the version does not match, or other problems occur, you need to delete the installed Node.js and reinstall the new version of Node.js. In addition, if you need to use other JavaScript development environments, you need to uninstall Node.js.

How to uninstall Node.js?

To uninstall Node.js on Mac, you can choose the following two methods:

1. Use the command line to uninstall Node.js

Step one: Open the terminal and enter the following command to display the installation path of Node.js:

which node

After executing this command, the installation path will be displayed: /usr/local/bin/node

Step 2: Enter the following command to delete Node.js related files:

sudo rm -rf /usr/local/bin/npm
sudo rm -rf /usr/local/share/man /man1/node.1
sudo rm -rf /usr/local/lib/dtrace/node.d
sudo rm -rf ~/.npm
sudo rm -rf ~/.node-gyp
sudo rm /usr/local/bin/node

This command will delete the Node.js executable file, npm package manager, man page, DTrace tracking file and related files in the user directory.

Step 3: Determine whether to completely uninstall Node.js. Enter the following command in the terminal:

node -v

If "command not found" is displayed, it means that it has been uninstalled.

2. Use the Node.js command tool to uninstall Node.js

Using the Node.js command tool simplifies the steps to uninstall Node.js, as follows:

Step one: Download and install npm of the Node version you want to use.

curl https://npmjs.org/install.sh | sh

This command will install the latest version of npm on the system.

Step 2: Use npm to uninstall Node.js.

sudo npm uninstall npm -g

This command will uninstall npm.

Step 3: Use the official package of Node.js to uninstall Node.js.

sudo rm /usr/local/bin/node

This command will delete the Node.js executable file.

It is recommended to use the first method to uninstall Node.js, because the commands in it can ensure that all related files are completely deleted, ensuring that there will be no problems with the next reinstallation.

It should be noted that before uninstalling Node.js, back up the project code and related configuration files to prevent accidental deletion.
