npm react 安装报错怎么办?

npm安装react时提示报错

在使用npx create-react-app的安装过程中出现了

6 high severity vulnerabilities

但是后续仍然显示成功安装,按照提示输入npm-audit时候却报错

 npm audit fix
npm ERR! code ENOLOCK
npm ERR! audit This command requires an existing lockfile.
npm ERR! audit Try creating one first with: npm i --package-lock-only
npm ERR! audit Original error: loadVirtual requires existing shrinkwrap file
 
npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\christine\AppData\Local\npm-cache\_logs\2022-10-10T08_34_39_142Z-debug-0.log

后续发现是自己把项目的路径输错了,正确输入项目路径时显示提示漏洞的原因

nth-check  <2.0.1
Severity: high
Inefficient Regular Expression Complexity in nth-check - https://github.com/advisories/GHSA-rp65-9cf3-cjxr
fix available via `npm audit fix --force`
Will install react-scripts@2.1.3, which is a breaking change
node_modules/svgo/node_modules/nth-check
  css-select  <=3.1.0
  Depends on vulnerable versions of nth-check
  node_modules/svgo/node_modules/css-select
    svgo  1.0.0 - 1.3.2
    Depends on vulnerable versions of css-select
    node_modules/svgo
      @svgr/plugin-svgo  <=5.5.0

        @svgr/webpack  4.0.0 - 5.5.0
        Depends on vulnerable versions of @svgr/plugin-svgo
        node_modules/@svgr/webpack
          react-scripts  >=2.1.4
          Depends on vulnerable versions of @svgr/webpack
          node_modules/react-scripts
 
6 high severity vulnerabilities

一个建议:忽略

npm提示可以使用`npm audit fix --force`进行修复,但是Don't be alarmed by vulnerabilities after NPM Install (voitanos.io)j

建议是忽略这些错误;因为npm只是包管理工具,他不能够解决包自身的缺陷和漏洞,如果强制修复解决的话,很有可能会引起更为严重的错误。

一定要尝试解决的话

打开项目中的package.json文件,找到dependencies对象

"dependencies":{
//……}

将其中的react.json移动到devDependencies(没有的话可以自己创建一个),你的版本可能与我的不同,但是这是无关紧要的,只需要移动即可

"devDependencies": {
    "react-scripts": "5.0.1"
  },

最后,在终端中运行npm audit --production,即可修复警告

Frontend Development with React: Advantages and TechniquesFrontend Development with React: Advantages and TechniquesApr 17, 2025 am 12:25 AM

The advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.

React vs. Other Frameworks: Comparing and Contrasting OptionsReact vs. Other Frameworks: Comparing and Contrasting OptionsApr 17, 2025 am 12:23 AM

React is a JavaScript library for building user interfaces, suitable for large and complex applications. 1. The core of React is componentization and virtual DOM, which improves UI rendering performance. 2. Compared with Vue, React is more flexible but has a steep learning curve, which is suitable for large projects. 3. Compared with Angular, React is lighter, dependent on the community ecology, and suitable for projects that require flexibility.

Demystifying React in HTML: How It All WorksDemystifying React in HTML: How It All WorksApr 17, 2025 am 12:21 AM

React operates in HTML via virtual DOM. 1) React uses JSX syntax to write HTML-like structures. 2) Virtual DOM management UI update, efficient rendering through Diffing algorithm. 3) Use ReactDOM.render() to render the component to the real DOM. 4) Optimization and best practices include using React.memo and component splitting to improve performance and maintainability.

React in Action: Examples of Real-World ApplicationsReact in Action: Examples of Real-World ApplicationsApr 17, 2025 am 12:20 AM

React is widely used in e-commerce, social media and data visualization. 1) E-commerce platforms use React to build shopping cart components, use useState to manage state, onClick to process events, and map function to render lists. 2) Social media applications interact with the API through useEffect to display dynamic content. 3) Data visualization uses react-chartjs-2 library to render charts, and component design is easy to embed applications.

Frontend Architecture with React: Best PracticesFrontend Architecture with React: Best PracticesApr 17, 2025 am 12:10 AM

Best practices for React front-end architecture include: 1. Component design and reuse: design a single responsibility, easy to understand and test components to achieve high reuse. 2. State management: Use useState, useReducer, ContextAPI or Redux/MobX to manage state to avoid excessive complexity. 3. Performance optimization: Optimize performance through React.memo, useCallback, useMemo and other methods to find the balance point. 4. Code organization and modularity: Organize code according to functional modules to improve manageability and maintainability. 5. Testing and Quality Assurance: Testing with Jest and ReactTestingLibrary to ensure the quality and reliability of the code

React Inside HTML: Integrating JavaScript for Dynamic Web PagesReact Inside HTML: Integrating JavaScript for Dynamic Web PagesApr 16, 2025 am 12:06 AM

To integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.

The Benefits of React: Performance, Reusability, and MoreThe Benefits of React: Performance, Reusability, and MoreApr 15, 2025 am 12:05 AM

React’s popularity includes its performance optimization, component reuse and a rich ecosystem. 1. Performance optimization achieves efficient updates through virtual DOM and diffing mechanisms. 2. Component Reuse Reduces duplicate code by reusable components. 3. Rich ecosystem and one-way data flow enhance the development experience.

React: Creating Dynamic and Interactive User InterfacesReact: Creating Dynamic and Interactive User InterfacesApr 14, 2025 am 12:08 AM

React is the tool of choice for building dynamic and interactive user interfaces. 1) Componentization and JSX make UI splitting and reusing simple. 2) State management is implemented through the useState hook to trigger UI updates. 3) The event processing mechanism responds to user interaction and improves user experience.

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),
