javascript - React.js - 使用“npx create-react-app”命令时的警告和错误
问题描述
尝试使用命令创建 react.js 应用程序时收到一些警告和错误消息npx creat-react-app
这是包含我得到的错误的终端输出。我还想指定当 react.js 应用程序创建时，无论这些错误如何，它实际上都在工作。但我担心如果缺少某些东西。Node.js 和所有必需的工具也已安装。
Node.js 版本：LTS 版本 12.18.4（包括 npm 6.14.6）

Removing .git directory...
Success! Created my-app at C:\Users\Administrator\Desktop\cmder\my-app
Inside that directory, you can run several commands:
npm start
Starts the development server.
npm run build
Bundles the app into static files for production.
npm test
Starts the test runner.
npm run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!
We suggest that you begin by typing:
cd my-app
npm start
Happy hacking!
解决方案
未创建 Git 提交错误：命令失败：git commit -m“使用 Create React App 初始化项目”
好像你没有安装 git。如果您希望 cra 初始化 git 存储库，请安装 git。如果你不打算使用 git，你应该忽略这个错误。
npm WARN notsup 跳过可选依赖：fsevents@2.1.2 不受支持的平台：想要 {"os":"darwin","arch":"any"}（当前：{"os":"win32","arch": "x64"})
这是 mac (darwin) 的可选依赖项
该线程指出您可以使用它npm install --no-optional来防止发生警告。
npm WARN tsutils@3.17.1 需要一个 typescript@>=2.8.0 || >= 3.2.0-dev || >= 3.3.0-dev || >= 3.4.0-dev || >= 3.5.0-dev || >= 3.6.0-dev || >= 3.6.0-beta || >= 3.7.0-dev || >= 3.7.0-beta 但没有安装。您必须自己安装对等依赖项。
好像 cra 使用 typescript 并要求您安装 2.8.0 以上的 typescript 版本。
npm i -g typescript
