我的一个依赖项具有.ts文件和.js文件,它们具有相同的名称,但扩展名不同。 Webpack正在获取.ts文件的解析器错误,并且错误总是在引入特定于打字稿的构造的地方出现,因此我认为是由JavaScript解析器发出了错误。运行npx tsc
会使一切正常编译,因此我知道源代码都是有效的。

这是我的错误信息:

You may need an appropriate loader to handle this file type.
| //---- Pack colors to BGRA8 instead of RGBA8 (if you needed to convert from one to another anyway)
| //#define IMGUI_USE_BGRA_PACKED_COLOR

@ ./node_modules/imgui-js/imgui.js 146:0-37 889:32-66 891:32-66
@ ./src/main.ts
@ ./src/index.ts
42:40的标记是冒号。
我已经尝试过ts-loader
和awesome-typescript-loader
,但是它们都给出相同的错误。
如果我删除
resolve: {
extensions: ['.tsx', '.ts', '.js']
},
从webpack.config.js,然后成功导入和编译模块。但是,然后import { bar } from './foo';
停止工作。错误:
ERROR in ./src/main.ts
Module not found: Error: Can't resolve './foo' in 'C:\Users\Hiiro\Development\KalaioThree\src'
@ ./src/main.ts 12:0-28 16:8-11
@ ./src/index.ts
因此,一个有效的解决方案是将我的所有源代码都保存在main.ts中。但是,这绝对不是理想的解决方案。我希望能够使用打字稿模块并导入自己的打字稿文件。
答案 0 :(得分:0)
原来是因为我排除了/ node_modules /文件夹:
module: {
rules: [
{
test: /\.tsx?$/,
use: 'ts-loader',
exclude: /node_modules/
}
]
}
删除该行使webpack可以为我提供更好的错误输出,并引导我解决问题。
为了完整起见,人们从Google找到了这个问题,我的解决方案最终是将其添加到我的webpack.config.js中:
resolve: {
extensions: ['.js', '.tsx', '.ts']
},
将.js条目作为第一个条目很重要,因为它阻止ts-loader尝试解析模块中的.ts文件,通常不建议这样做。
