离子3 - 所有进口都是未使用的警告（即使它们被使用） [英] Ionic 3 - All imports are unused warning (even though they are being used)

问题描述

尝试使用以下内容运行prod构建时出现以下错误

I am getting the following error when trying to run a prod build using the following

ionic cordova build browser --prod

ionic cordova build browser --prod

在终端中收到很多警告，如

Getting lot of warnings in the terminal like

FormBuilder已声明但从未使用

FormBuilder is declared but never used

即使在我的代码中我导入并使用它，例如

Even though in my code I am importing it and using it e.g.

import { Validators, FormGroup, FormBuilder } from '@angular/forms';

public form: FormGroup;

constructor(
    private formBuilder: FormBuilder
  ) {

setForm(){
    this.form = this.formBuilder.group({
      password: ['', Validators.required],
      password2: ['', Validators.required]
    });
  }

有没有人有过类似的问题？我的猜测是与npm包更新有关。

Has anyone had a similar problem? My guess it would be something to do with an npm package update.

任何建议都会很棒。

谢谢！

推荐答案

Ionic 3.3.0（2017-05-24）删除了旧文件'src / declarations.d的用法.ts'，如 changelog 。从src /文件夹中删除'declarations.d.ts'可修复未使用的导入警告。

Ionic 3.3.0 (2017-05-24) removed the usage of legacy file 'src/declarations.d.ts' as mentioned in the changelog. Removing 'declarations.d.ts' from the src/ folder fixes the unused imports warning.
