Ignore "cannot find module" error on typescript
提问by Rafael
Can the Typescript compiler ignore the cannot find module 'x'error on import expressions such as:
Typescript 编译器可以忽略cannot find module 'x'导入表达式的错误，例如：
//How to tell the compiler that this module does exists
import sql = require('sql');
There are multiple npm libraries such as node sqlthat doesn't have existing typings
有多个 npm 库，例如node sql没有现有的类型
Is there a way to tell the compiler to ignore this error other than creating a new definition file with the declare module x ...?
除了使用declare module x ...?创建新定义文件之外，有没有办法告诉编译器忽略此错误？

If you just want to bypass the compiler, you can create a .d.ts file for that module, for instance, you could create a sql.d.ts file and inside have this:
如果你只想绕过编译器，你可以为那个模块创建一个 .d.ts 文件，例如，你可以创建一个 sql.d.ts 文件，里面有这个：
declare module "sql" {
let _sql: any;
export = _sql;
}

As of TypeScript 2.6 (released on Oct 31, 2017), now there is a way to ignore all errors from a specific lineusing // @ts-ignorecomments before the target line.
从 TypeScript 2.6（2017 年 10 月 31 日发布）开始，现在有一种方法可以使用// @ts-ignore目标行之前的注释来忽略特定行中的所有错误。
The mendtioned documentationis succinct enough, but to recap:
提到的文档足够简洁，但要回顾一下：
// @ts-ignore
const s : string = false
disables error reporting for this line.
禁用此行的错误报告。
However, this should only be used as a last resort when fixing the error or using hacks like (x as any)is much more trouble than losing all type checking for a line.
然而，这应该只在修复错误或使用 hacks 时作为最后的手段使用，比如(x as any)比丢失一行的所有类型检查更麻烦。
As for specifying certain errors, the current (mid-2018) state is discussed here, in Design Meeting Notes (2/16/2018) and further comments, which is basically
至于指定某些错误，这里讨论了当前（2018 年中期）的状态，在设计会议笔记（2/16/2018）和进一步的评论中，基本上是
"no conclusion yet"
“没有定论尚”
and strong opposition to introducing this fine tuning.
并且强烈反对引入这种微调。

Solved ThisBy default @ts-check looks for definitions of a module, either its your own code or external libraries.
解决了这个默认情况下@ts-check 查找模块的定义，无论是您自己的代码还是外部库。
Since we are not using ES6 style modules, then we must we are using commonjs, check my jsconfig.json file for help.
既然我们没有使用 ES6 风格的模块，那么我们必须使用 commonjs，检查我的 jsconfig.json 文件以获得帮助。
{
"compilerOptions": {
"target": "es6",
"module": "commonjs",
"lib": ["es5", "es6", "es7"]
},
"include": ["src/**/*"],
"exclude": ["node_modules"],
"typeAcquisition": { "enable": true }
}
