Sweetalert没有运行，我在它的TS文件上得到一个错误的信息

Question

我正在给一个应用程序与Angular 7.0.7和Node 10.20.1.我都工作得很好，我安装了很久以前Sweetalert和插件工作得很好。昨天，我的电脑重启，当我执行 ng serve 我得到了这个错误

node_modulessweetalert2sweetalert2.d.ts(277,39)中的错误：TS1005: ','预期。 node_modulessweetalert2sweetalert2.d.ts(277,68): 错误 TS1011: node_modulessweetalert2sweetalert2.d.ts(277,69): error TS1005: ';' expected. node_modulessweetalert2sweetalert2.d.ts(277,70): error TS1128: declaration or statement expected. node_modulessweetalert2sweetalert2.d.ts(277,82): error TS1005: '(' expected.

  }
}

我做了很多手脚

• 删除并安装了所有的node_modules，并将其与 npm install，没有工作
• 我把typescript降到了2.X版本，但没有用。
• 重新安装只有甜味剂与 npm uninstall sweetalert2 && npm install sweetalert2，没有工作
• 我跑了 npm audit fix，我收到了很多问题的应用程序，没有作品

我去了sweetalert文件，在错误行发现了这段代码。

/**
     * Provide an array of SweetAlert2 parameters to show multiple popups, one popup after another.
     *
     * @param steps The steps' configuration.
     */
    function queue<T>(steps: readonly (SweetAlertOptions | string)[]): Promise<T>;

在所有的情况下，都是同样的错误......是什么问题？

Answer 1

你好，我也开始面临同样的问题。找到了一个修复的时间，直到一个更好的解决方案来了，我只是降级了。

npm安装[email protected]

Answer 2

很好，你只要把 "readonly "去掉，应用程序就可以工作了。
