问题描述
我在 node_modules
中有一些模块 lib
并且我想使用它.我为此编写了 lib.d.ts
.
I have some module lib
in node_modules
and I want to use it.I wrote lib.d.ts
for this.
文件看起来像:
/src/
main.ts (imports `lib`)
/types/
lib.d.ts
在文件 main.ts
中我可以写这个代码:
In file main.ts
I can write this code:
/// <reference path="../types/lib.d.ts" />
import {some} from 'lib';
它有效.
但是当我尝试对环境声明文件使用导入时:
But when I try to use import for ambient declaration file:
import '../types/lib';
import {some} from 'lib';
它编译没有错误,但在生成的 JS 中我可以找到这个文件的要求:
it compiles without errors, but in resulting JS I can find require for this file:
require('../types/lib');
const lib_1 = require('lib');
丢失文件运行时出错 ../types/lib
–它只是一个环境声明文件,没有结果文件.
With error in runtime of missing file ../types/lib
–it's just an ambient declaration file without resulting file.
为什么编译器没有删除 *.d.ts 文件的导入?
我可以以某种方式使用导入,还是必须使用引用?
Why compiler did not remove import of *.d.ts file?
Can I use import somehow, or I must use reference instead?
解决方案:
如果您不想使用 reference
指令,您可以将所需的 *.d.ts 添加到文件中,包含在您的 tsconfig.json 中.
If you don't want to use reference
directives,you can just add required *.d.ts to files,included by your tsconfig.json.
我的 tsconfig.json 是:
My tsconfig.json was:
{
"compilerOptions": {
"module": "commonjs",
"target": "es2015",
"lib": ["es2016"],
"noImplicitAny": true,
"noImplicitReturns": true,
"noImplicitThis": true,
"strictNullChecks": true,
"noFallthroughCasesInSwitch": true,
"noUnusedLocals": true,
"noUnusedParameters": true,
"noEmitOnError": true,
"newLine": "LF",
"forceConsistentCasingInFileNames": true,
"removeComments": true,
"declaration": false,
"sourceMap": false,
"outDir": "../build",
"types": [
"node"
]
},
"files": [
"index.ts"
]
}
早期我尝试将我的 .d.ts 添加到 types
部分,但在这种情况下tcs 正在尝试在 node_modules/@types 目录中找到此文件.
Early I tried to add my .d.ts to types
section, but in this casetcs is trying to find this file in node_modules/@types directory.
根据建议,我尝试在 files
部分添加文件:
After suggestion I tried to add file in files
section:
"files": [
"index.ts",
"types/lib.d.ts"
]
它很有效,而且似乎是一个不错的解决方案.
It's works and seems as a good solution.
推荐答案
您不必导入
环境定义文件.
您可以手动///它.但正确的方法是通过文件
tsconfig.json
使其可供编译器使用.
You can manually /// <reference
it. But the right way is just to make it available for the compiler through the file tsconfig.json
.
一个 tsconfig.json
的例子,它包含除 node_modules
之外的任何内容:
An example of tsconfig.json
that includes anything but node_modules
:
{
"compilerOptions": {
"module": "commonjs",
"target": "es5"
},
"exclude": [
"node_modules"
]
}
The documentation on tsconfig.json
is here.
