全局安裝ts命令 npm install -g typescript
安裝結束后運行tsc -v命令 顯示版本號表示安裝成功
接下來可以使用tsc 文件名稱 可以將ts文件轉化為js文件 js文件可以引入在html文件中直接使用
在文件夾中執行 tsc --init 可以生成tsconfig.json文件 打開該文件可以看到 內容如下
{ "compilerOptions": { /* Visit https://aka.ms/tsconfig.json to read more about this file */ /* Projects */ // "incremental": true, /* Enable incremental compilation */ // "composite": true, /* Enable constraints that allow a TypeScript project to be used with project references. */ // "tsBuildInfoFile": "./", /* Specify the folder for .tsbuildinfo incremental compilation files. */ // "disableSourceOfProjectReferenceRedirect": true, /* Disable preferring source files instead of declaration files when referencing composite projects */ // "disableSolutionSearching": true, /* Opt a project out of multi-project reference checking when editing. */ // "disableReferencedProjectLoad": true, /* Reduce the number of projects loaded automatically by TypeScript. */ /* Language and Environment */ "target": "es2016", /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */ // "lib": [], /* Specify a set of bundled library declaration files that describe the target runtime environment. */ // "jsx": "preserve", /* Specify what JSX code is generated. */ // "experimentalDecorators": true, /* Enable experimental support for TC39 stage 2 draft decorators. */ // "emitDecoratorMetadata": true, /* Emit design-type metadata for decorated declarations in source files. */ // "jsxFactory": "", /* Specify the JSX factory function used when targeting React JSX emit, e.g. 'React.createElement' or 'h' */ // "jsxFragmentFactory": "", /* Specify the JSX Fragment reference used for fragments when targeting React JSX emit e.g. 'React.Fragment' or 'Fragment'. */ // "jsxImportSource": "", /* Specify module specifier used to import the JSX factory functions when using `jsx: react-jsx*`.` */ // "reactNamespace": "", /* Specify the object invoked for `createElement`.

結束后可以點擊vscode的終端 點擊配置任務 選擇tsc監視 如果報錯 并且錯誤內容大致如下
無法加載文件 C:\Users\Administrator\AppData\Roaming\npm\tsc.ps1,因為在此系統上禁止運行腳本
這時候需要單開 window powershell ise 輸入命令 Set-ExecutionPolicy RemoteSigned 點擊全是 再次執行監視任務即可正常監視
再次點擊終端 點擊運行任務 選擇 tsc監視 即可實時監視ts文件的變化 并自定生成對應的js文件
