//file-a.ts
type Foo = {
}
//file-b.ts
type Foo = {
}
如果我试着编译这个,我会得到:
error TS2300: Duplicate identifier 'Foo'.
我使用的是TypeScript3.7.5版本,我的tsconfig.json有这些属性(所有其他默认值):
{
"compilerOptions": {
"target": "es5", /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', 'ES2018', 'ES2019' or 'ESNEXT'. */
"module": "commonjs", /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */
"outDir": "./dist", /* Redirect output structure to the directory. */
"rootDir": "./src", /* Specify the root directory of input files. Use to control the output directory structure with --outDir. */
"isolatedModules": true, /* Transpile each file as a separate module (similar to 'ts.transpileModule'). */
"strict": true, /* Enable all strict type-checking options. */
"esModuleInterop": true, /* Enables emit interoperability between CommonJS and ES Modules via creation of namespace objects for all imports. Implies 'allowSyntheticDefaultImports'. */
"forceConsistentCasingInFileNames": true /* Disallow inconsistently-cased references to the same file. */
}
}
The actual code here.
