typescript - Ionic App 中的 TypeScript 错误：无法在 Firebase 登录中使用异步

Question

在我的 ionic 应用程序中，我正在尝试创建一个注册代码，该代码将检查数据库中的重复条目，如果没有找到重复条目，它将允许用户使用电子邮件和密码创建帐户。当用户想要注册时，他/她必须提供用户数据和唯一的 GroupID，如果此 GroupID 在数据库中已经可用，则用户无法使用该 GroupID 注册。

async signup(): Promise<void> {
    this.checkValidEmail(this.user.email, (isError) => {
        if (isError) {
            console.log("Error : Already has this email address ");
            this.error = "Already has this email address in out system";
        } else {
            this.checkValidGroup(this.user.GroupName, (isError1) => {
                if (isError1) {
                    console.log("Error : Thid Group Id is already Taken ");
                    this.error = "This Group ID is not available";
                }
                // this.userService.pushUser(this.user);
                else if (this.matchPassword(this.user)) {
                    console.log("Error :Don't metch password");
                    this.error = "Don't metch between Password and confirm password";
                } else if (this.user.password.length < 6) {
                    console.log("Error : passwrod short");
                    this.error = "Password is too short (minimum is 6 characters).";
                } else {
                    this.deleteconfirm(this.user);
                    var pass = Md5.hashStr(this.user.password);
                    this.user.password = pass.toString();
                    var pin = Md5.hashStr(this.user.passcode);
                    this.user.passcode = pin.toString();

                    const loading: Loading = this.loadingCtrl.create();
                    loading.present();

                    const email = this.user.email;
                    const password = this.user.password;
                    try {
                        const signup: firebase.User = await this.authProvider.signup(
                            email,
                            password
                        );
                        await loading.dismiss();

                        if (this.userService.pushUser(this.user)) {
                            this.navCtrl.setRoot(TabsPage);
                            this.navCtrl.push(TabsPage);
                        }

                    } catch (error) {
                        await loading.dismiss();
                        const alert: Alert = this.alertCtrl.create({
                            message: error.message,
                            buttons: [{
                                text: 'Ok',
                                role: 'cancel'
                            }]
                        });
                        alert.present();
                    }

                }
            });
        }
    });

}

但是这段代码显示了一些错误，例如

Cannot find name 'await'.

有Property 'signup' does not exist on type 'AuthProvider'.什么帮助吗？
