Nodejs cannot write commands in vscode

Node.js is a JavaScript runtime based on the Chrome V8 engine. It helps developers build high-performance, scalable web applications, while Visual Studio Code is a free code editor and one of the most popular code editors.

Many people like to use Node.js to write back-end logic, and they also use Visual Studio Code for development. However, when you use Node.js in Visual Studio Code, you may find a tricky problem: you cannot enter commands in the terminal.

The reason for this problem is that the terminal in Visual Studio Code uses PowerShell by default instead of the command prompt, which is often called CMD. Node.js is typically developed and tested interactively using the command prompt and does not support entering commands in PowerShell.

So, how to configure the use of command prompt in Visual Studio Code? Below we will introduce two solutions.

Solution 1: Use external terminal

Visual Studio Code supports the use of external terminals, such as CMD, Git Bash, etc., which can be configured in the settings. The following are the specific steps:

1. Open Visual Studio Code;
2. Click the "Settings" icon on the left, or use the shortcut key "Ctrl," to open the settings;
3. Enter "terminal.integrated.shell.windows" in the search box;
4. Click "Edit in settings.json" and change the default settings to "terminal.integrated.shell.windows": "C:\ Windows\System32\cmd.exe";
5. Now you can run Node.js commands in an external terminal, such as entering "node -v" to view the current version number of Node.js.

Solution 2: Install and use plug-ins

Visual Studio Code has a large number of plug-ins that can be used to enhance its functionality, and there are also many plug-ins that can help us solve this problem. The following are two popular plug-ins:

1. "Code Runner"

This plug-in can run code directly in the editor of Visual Studio Code and supports many programming language. You can install it by typing "code runner" in the terminal.

2. "Node.js Exec"

This plug-in allows you to use Node.js in Visual Studio Code and supports entering commands in the terminal, which is very suitable for Node. js development and testing. You can install it by typing "nodejs exec" in the terminal.

Summary

Node.js is a very powerful tool that can help us develop high-performance, scalable web applications. Using Visual Studio Code also makes our development work more efficient and enjoyable. When encountering problems, we should learn to find and solve them. For example, the problem of being unable to enter Node.js commands in Visual Studio Code can be solved by using an external terminal or installing a plug-in. The most important thing is that we must maintain our curiosity and spirit of exploration about new technologies, and continue to learn and improve our skills.
