我的Angular应用程序目前位于4.1.3 Typescript@2.0.3。我读到Typescript大于2.0时，应使用@types。
目前我在应用程序中安装了打字。要迁移到使用@types，我有3个问题：
1.我应该从typings和package.json中删除tsconfig.json吗？并安装@types个包裹？
@types软件包？typings.json档吗？的package.json：

答案 0 :(得分：0)
typings目录中的输入，以及3. typings.json。但是，您应该在@types中配置tsconfig.json：{
"compilerOptions": {
"typeRoots": [ // it should do the job
"node_modules/@types"
],
"types": [ // alternatively here you can list needed typings
"node",
"jasmine",
"webpack",
"lodash"
// ... etc.
]
}
}
2。现在使用typings的库将需要相应的@types个包。查找它们的最简单方法是npmjs.com search engine，然后安装它们：
npm install @types/webpack --save
希望它对你有所帮助。
