Question

我正在尝试将我的angular 2应用程序升级到angular7。我根据以下文章运行了所有命令。 https://medium.com/@jeroenouw/upgrade-to-angular-7-beta-within-10-minutes-c14fc380edd

但是我正在获得例外。当我运行“ npm install”时。

TSError：⨯无法编译TypeScript： gulpfile.ts（22,5）：错误TS2349：无法调用类型缺少调用签名的表达式。输入'{默认值：IRunSequence; use（gulp：Gulp）：IRunSequence; }'没有兼容的呼叫签名。

我收到异常的gulpfile.ts的代码段。

let firstRun = true;
gulp.task('clean.once', (done: any) => {
  if (firstRun) {
    firstRun = false;
    //BELOW IS THE LINE WHERE IT HAS COMPILATION
    runSequence('check.tools', 'clean.dev', 'clean.coverage', done);
  } else {
    util.log('Skipping clean on rebuild');
    done();
  }

输入'{默认值：IRunSequence; use（gulp：Gulp）：IRunSequence; }'没有兼容的呼叫签名
