What should I do if cmd shows that node is not an internal command?

cmd prompts 'node' is not an internal or external command, nor is it an operable program. Solution

Error condition:

When running the node -xxx command in the cmd window, the prompt 'node' is not an internal or external command, nor an operable program or batch file

Cause:

The environment variables are not configured correctly.

In fact, my situation is that it is not configured at all...The default location was changed during installation. This problem occurred when node -v was used, and environment variables need to be configured

Configuring environment variables :

(The installation path of my node.js is F:\Download\nodejs. When modifying the environment variables, just modify them according to your own installation directory)

windows system Here, you need to set the nodejs installation directory path into the system variable or user variable

1. Open the Control Panel->System and Security->System->Advanced System Settings->Environment Variables

If nodejs is in the user directory, both NODE_PATH and PATH are set in user variables

2. Find variables in "User Variables" or "System Variables" PATH and add node.js folder path as value. Usually it is C:\Program Files\nodejs;. If the variable does not exist, it is created.

Create variables: Take the variable I created as an example, create a new one in the user variable, enter the variable name - NODE_PATH, enter the value - F:\Download\nodejs, if there is no PATH variable in the user variable, create a new one PATH variable, the value is %NODE_PATH%, if there is one, just add the value

3.win R: Restart the cmd window (enter cmd after win R to open the command window), enter node -v in the command window Check the version number. If you can check the environment variable configuration is successful
