How to uninstall nodejs environment variables
Node.js is a popular JavaScript runtime that is widely used in web development and other applications. However, if you no longer need to use Node.js, or want to uninstall the old version to install the new version, then you will need to uninstall the Node.js environment variable. In this article, we will explain how to uninstall Node.js environment variables.
Step 1: Check Node.js version and path
Before uninstalling Node.js, you need to determine which version is running and find its installation path. To check the version and path of Node.js, open a command prompt or terminal and enter the following command:
node -v // 查看Node.js版本号 where node // 查找Node.js安装路径
If you are using Linux or macOS, use the which node command to find Node.js path of.
Step 2: Delete environment variables
If you have found the path to Node.js, the next step is to delete the system environment variables. In order to uninstall Node.js, you need to delete the path to Node.js as it will no longer be needed.
In Windows systems, do the following:
- Open "Control Panel" and select "System and Security."
- Click on the "System" tab.
- Select "Advanced System Settings".
- Under the "Advanced" tab, click "Environment Variables".
- In the system variable list, find the "Path" variable and click "Edit".
- In the Edit Environment Variables dialog box, find the Node.js path and click Delete.
- Click OK to save changes.
On Linux and macOS systems, you need to edit the Bash configuration file. Open the terminal and enter the following command:
nano ~/.bashrc
This command will start the nano editor and open the Bash configuration file. In this file, find the line containing the path to Node.js and delete it. Press Ctrl X to save changes and exit the nano editor.
Step 3: Delete the Node.js file
Now, you have deleted the Node.js environment variable, but the installation file is still on your computer. In order to completely uninstall Node.js, you need to delete the files related to it.
On Windows systems, open File Explorer and navigate to the Node.js installation path. Delete the folder and any subfolders and files within it.
In Linux and macOS systems, open a terminal and enter the following command:
sudo rm -rf /usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man/*/node.*}
This command will delete all files and folders for Node.js and NPM. Note that some systems may require additional removal commands.
After completing the above steps, you have uninstalled Node.js from your computer. If you decide to install Node.js again, remember to follow the official installation guide to ensure that environment variables and files are configured correctly.
Summary:
Uninstalling Node.js environment variables requires three steps: check the Node.js version and path, delete the environment variables, and delete the Node.js file. These steps ensure that Node.js is completely uninstalled from your computer, leaving enough space for a new installation or other operations.
