找不到“ramda”的类型定义文件

Question

我有一个Ionic 2 & Angular 2 的项目。

我在我的代码中使用 RamdaJS，这与这些命令完美配合：

• ionic serve
• ionic cordova build android
• ionic cordova run android

但是当我尝试执行这个命令时：ionic cordova build android --prod --release，我得到一个关于 Ramda 和 Type 的错误。

查看我的package.json的一部分：

尝试构建生产时出错：

Error: Failed to transpile TypeScript

Answer 1

按照此处的安装说明进行操作：https://github.com/types/npm-ramda

# using npm
npm install --save-dev types/npm-ramda#dist

如果不使用 npm/yarn，您可能需要将这些类型添加到路径中 tsconfig.json：

完整包装：

{
  "compilerOptions": {
    "baseUrl": "./",
    "paths" : {
       "ramda": [
         "location-of-types/npm-ramda-package/index"
       ]
     }
  }
}

Answer 2

按照DefinitlyTyped 的建议通过@types/packageName 安装类型。

对于 NPM 做：

npm install @types/ramda --save-dev

对于 YARN 使用：

yarn add @types/ramda --dev

Typescript 默认在 node_modules 中查找名为 @types 的目录以查找类型定义：

默认情况下，所有可见的“@types”包都包含在您的编译中。任何封闭文件夹的 node_modules/@types 中的包都被认为是可见的；具体来说，这意味着 ./node_modules/@types/、../node_modules/@types/、../../node_modules/@types/ 等中的包。

如果指定了 typeRoots，则只包含 typeRoots 下的包。
