Question

で重複識別子「要素」エラー：

{ 
    "compilerOptions": { 
     "module": "system", 
     "noImplicitAny": true, 
     "removeComments": true, 
     "preserveConstEnums": true, 
     "sourceMap": true 
    }, 
    "include": [ 
     "src/ts/*.ts" 
    ], 
    "exclude": [ 
     "node_modules", 
     "**/*.spec.ts" 
    ] 
} 

は、これが私のGulpfileです：

const gulp = require('gulp'); 
const sass = require('gulp-sass'); 
const ts = require('gulp-typescript'); 
const tsProject = ts.createProject('tsconfig.json'); 

const tasks = { 
    css:() => { 
     return gulp.src('./src/scss/*.scss') 
      .pipe(sass().on('error', sass.logError)) 
      .pipe(gulp.dest('./dist/css')); 
    }, 
    js:() => { 
     return tsProject.src() 
      .pipe(tsProject()) 
      .js.pipe(gulp.dest('./dist/js/')); 
    } 
}; 

gulp.task('js',() => { 
    tasks.js(); 
}); 

gulp.task('css',() => { 
    tasks.css(); 
}); 

これはエラートレースです：

$ gulp js

Answer 1

それ私がのElemにElementクラスの名前を変更した後に動作します - Elementのように見えます。
