Question

嗨，我正在尝试运行一个简单的量角器测试（protracotor的新手），但是我一直收到此错误。下面是我的package.json

    "@angular-devkit/build-angular": "~0.803.8",
    "@angular/cli": "~8.3.8",

  }

Answer 1

就我而言，问题是由于组件中的错误导入造成的。

我写错了

Server says: Hello client
Enter something for the server: hi
Client says: hi

而不是在导入下面写：

import { EventEmitter } from 'protractor';

Answer 2

似乎存在兼容性问题：https://github.com/angular/protractor/issues/5348

我已通过将打字稿从3.7.X降级到 3.6.2 来解决此问题

Answer 3

如果您不想降级，则可以通过以下方式修复导入（量角器5.4.2）：

@Entity
@Table(name ="TRACK")
public class Track {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "TRACK_ID")
    private Long trackId;

    private String trackName;

    @OneToMany(cascade = CascadeType.ALL,
            orphanRemoval = true)
    @JoinColumn(name = "POINT_ID")
    private List<Point> point;

    @OneToOne
    @JoinColumn(name="TRACK_STATISTIC_ID")
    private TrackStatistic trackStatistic;

    private long numberOfLikes;

    private Date creationTime;

基本上，有一个伪造的进口，我们需要摆脱。随附有补丁程序：

@Entity
@Table(name = "USER")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name = "USER_ID")
    private Long userId;

    private String firstName;

    private String lastName;

    @Column(unique = true)
    private String username;

    private String password;

    @Column(unique = true)
    private String email;

    @Column(unique = true)
    private String phoneNumber;

    private int age;

    private Role role;

    private boolean locked;

    private long numberOfReports;

    @JsonIgnore
    @ManyToMany()
    @JoinTable(name="FOLLOWER",
            joinColumns={@JoinColumn(name="USER_ID")},
            inverseJoinColumns={@JoinColumn(name="FOLLOWER_ID")})
    private Set<User> followed = new HashSet<User>();

    @JsonIgnore
    @ManyToMany(mappedBy="followed")
    private Set<User> follower = new HashSet<User>();

   //How it was before
    @OneToMany
    @JoinColumn(name = "TRACK_ID")
    private List<Track> tracks;

   //How is it now
    @OneToMany
    @JoinColumn(name = "USER_ID")
    private List<Track> tracks;


    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
    @JoinColumn(name = "SHARE_ID")
    private List<Share> shares;
