cmd does not display after nodejs is installed

Node.js is a very popular JavaScript running environment, and many front-end developers and back-end developers use it for development. But sometimes, after installing Node.js, we may encounter some problems. For example, on the Windows operating system, after installing Node.js, the cmd command prompt may not display Node.js. This problem may make you Feeling confused and helpless. This article will explain and solve this problem.

1. View environment variables

The first step is to ensure that the path where Node.js is located has been added to the environment variables. If the environment variable is not added, you need to add it manually. Here are the steps to add environment variables:

Right-click this computer, select "Properties", and then select "Advanced System Settings".

In the "System Properties" dialog box, select the "Advanced" tab, and then click "Environment Variables".

In the "Environment Variables" dialog box, find "Path" under "System Variables" and click "Edit".

In this window you will see a long semicolon separated list of system paths. Add the path to Node.js at the bottom of the list. For example, "C:Program Files
odejs" or "C:Program Files (x86)
odejs".

2. Restart the command prompt

After adding the path, you need to restart the cmd command prompt. This way all new environment variables can be changed so that Node.js is found correctly.

3. Check if Node.js is installed correctly

If you still cannot access Node.js after restarting the cmd command prompt, it may be because of your Node.js installation has a problem. Try reinstalling Node.js and make sure it is installed correctly. It is important to note that 64-bit Windows requires the 64-bit version of Node.js to be installed, while 32-bit Windows requires the 32-bit version of Node.js to be installed.

4. Change the Node.js installation path

If Node.js still cannot be found, the installation path may be wrong. Before reinstalling Node.js, you can try changing the Node.js installation path to see if that resolves the issue. When you reinstall Node.js, make sure it is installed in a folder you have access to.

5. Install a new version of Node.js

If all the above steps fail to solve the problem, the Node.js version may be too old and need to be updated to the latest version . Download the latest Node.js version from the Node.js website and install it.

Summary

The inability to find Node.js in the cmd command prompt may be due to errors in the environment variables, Node.js installation path, or Node.js version. This issue can be resolved by using the solutions listed above. When dealing with this problem, you need to understand some basic knowledge in the Windows environment before using Node.js, and update the Node.js version regularly. If you still encounter problems, you can seek professional help or contact developers from the Node.js community for help and support.
