Question

Having trouble building an old typescript project. Unable to build an old project that I am coming back to. There is an issue with q when trying to build. I assume it is my tsc version, but every version I have tried results in errors.

There were some suggestions online to change the typescript version to past 2.2 because it handles typings differently, but nothing has resulted in any progress.

I have provided error information, and versions. Also my tsconfig.json. Please let me know if you need more information.

Errors ($tsc -v 2.1.5)

$ tsc -p ./
typings/modules/q/index.d.ts(10,1): error TS1316: Global module exports may only appear at top level.

Versions

nvm: 1.1.5
npm: 4.1.2
tsc: 2.1.5
node: 7.5.0

$ npm list --depth=0
+-- @types/q@1.5.1
`-- typescript@2.1.5

tsconfig.json

{
    "compilerOptions": {
        "target": "es5",
        "module": "amd",
        "outDir": "static/js",
        "sourceMap": true,
        "strictNullChecks": true,
        "noImplicitAny": true
    },
    "files": [
        "typings/index.d.ts",
        "../common/types.d.ts"
    ],
    "include": [
        "src/**/*.ts"
    ]
}

EDIT

The errors listed under tsc v2.3.0 were actually still 2.1.5. I didn't install typepscript globally, so it was still using 2.1.5 instead of 2.3.0 when I ran the tsc command.

当声明文件中出现错误时，通常表明声明文件使用的语法在您的TypeScript版本中不可用。

在这种情况下，让我们看一下报告为错误的行。

64: then<U = T, V = never>(onFulfill?: ...
200: thenReject<U = T>(reason?: any): Promise<U>;

此处报告的错误指向类型实参部分中的等号。这表明不支持默认类型参数。由于在TS2.3中添加了对default type arguments的支持，因此这实际上没有任何意义。我最好的猜测是您实际上没有为这些错误安装2.3，并且版本已切换...

请牢记，其他错误可能是由于旧的typings文件和新的@types文件（<2.1，如果我没记错的话）之间的不兼容所致。使用node_modules/@types/q中安装的类型，您无需包括自定义的typings文件夹，因此您应该能够删除typings/modules/q（实际上，整个typings文件夹）来解决其他错误。

如果这不能解决您的问题，那么通过克隆项目可以更轻松地找出问题所在。
