Introduction to node.js installation and configuration environment and methods of deploying projects (under Windows system)

1. Operation steps

①Download node.js

②Install and configure environment variables

③ Deployment project startup access

[Video tutorial recommendation: nodejs tutorial]

2. Detailed steps

1. Select the corresponding system to download :https://nodejs.org/en/download/




##2. Double-click to install







##3,
cmd installed

node -v 显示Node.js的版本说明已经安装成功
npm -v 自带的npm已经安装成功

installed As shown in the figure:

Here is a description: The new version of Node.js has its own npm, which will be installed when Node.js is installed. The function of npm is to carry out the packages that Node.js depends on. Management can also be understood as the things needed to install/uninstall Node.js.

4, Environment variable configuration

Instructions: Here The environment configuration mainly configures the path where the global module installed by npm is located, and the path of the cache. The reason for configuring it is because in the future, it is similar to: npm install express [-g] (the optional parameter -g later, g stands for global installation), the installed module will be installed in the path [C:\Users\username\AppData\Roaming\npm], occupying C drive space.

例如:我希望将全模块所在路径和缓存路径放在我node.js安装的文件夹中,则在我安装的文件夹【D:\Develop\nodejs】下创建两个文件夹【node_global】及【node_cache】如下图:

创建完两个空文件夹之后,打开cmd命令窗口,输入

npm config set prefix "D:\Develop\nodejs\node_global"
npm config set cache "D:\Develop\nodejs\node_cache"


接下来设置环境变量,关闭cmd窗口,“我的电脑”-右键-“属性”-“高级系统设置”-“高级”-“环境变量”




5、测试

配置完后,安装个module测试下,我们就安装最常用的express模块,打开cmd窗口,

输入如下命令进行模块的全局安装:

npm install express -g     # -g是全局安装的意思


安装完可以看到express版本



6、安装cnpm 下载国内资源

npm install -g cnpm --registry=https://registry.npm.taobao.org

输入cnpm -v输入是否正常

cnpm -v


如果有错

添加系统变量path的内容

  因为cnpm会被安装到D:\Program Files\nodejs\node_global下,而系统变量path并未包含该路径。在系统变量path下添加该路径即可正常使用cnpm。

7、部署项目

cnpm install


8、启动项目

npm run dev


启动成功


访问项目


At this point, installing node.js under Windows, configuring environment variables, and deploying the project are over. If you have any questions, leave a comment and we will reply as soon as possible.

Python vs. JavaScript: Development Environments and ToolsPython vs. JavaScript: Development Environments and ToolsApr 26, 2025 am 12:09 AM

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Is JavaScript Written in C? Examining the EvidenceIs JavaScript Written in C? Examining the EvidenceApr 25, 2025 am 12:15 AM

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript's Role: Making the Web Interactive and DynamicJavaScript's Role: Making the Web Interactive and DynamicApr 24, 2025 am 12:12 AM

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C   and JavaScript: The Connection ExplainedC and JavaScript: The Connection ExplainedApr 23, 2025 am 12:07 AM

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

From Websites to Apps: The Diverse Applications of JavaScriptFrom Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python vs. JavaScript: Use Cases and Applications ComparedPython vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

The Role of C/C   in JavaScript Interpreters and CompilersThe Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript in Action: Real-World Examples and ProjectsJavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
