angular2，typescript peer无效，无法导入模块

Question

我有两个问题，可能是它相互依赖：

1. 我不能要求/导入sass@0.5.0
2. 打字稿有效，但我看错了

通过命令npm list：

├── sass@0.5.0 extraneous
├── systemjs@0.19.27
├── typescript@1.8.10 peer invalid
├── typings@1.3.3
└── zone.js@0.6.17

npm ERR! extraneous: sass@0.5.0 C:\Users\AxOn\Documents\projects\NODETS+ANGULAR2\public\node_modules\sass
npm ERR! peer invalid: typescript@1.8.10 C:\Users\AxOn\Documents\projects\NODETS+ANGULAR2\public\node_modules\typescript

可能，因为typescript@1.8.10对等无效我看不到模块：

从'sass'导入{sass}; //错误

之后，在packege.json中没有sass

"devDependencies": {
    "concurrently": "^2.2.0",
    "lite-server": "^2.2.2",
    "typescript": "^1.8.10",
    "typings":"^1.3.2"
  }

Answer 1

将typescript的版本设置为2.0.2有助于修复我的案例中的打字稿错误。

"devDependencies": {
    // other dependecies ...
    "typescript": "^2.0.2",
    // other dependecies ...
  }

可能是这个错误是角度编译器及其依赖项升级的结果，而忘记升级文档。
