TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode dexie.js

Question

谁能告诉我当我调用 dexie.js 的 count() 函数时发生了什么：

TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them
    at eval (eval at getErrorWithStack (http://127.0.0.1:8081/elements/js/dexie.js:394:5), <anonymous>:1:19)

    at HTMLElement.checkLoadEnoughtOfflineData (http://127.0.0.1:8081/elements/base/app-localize-behavior.html:294:73)

上面最后一行是我函数的调用：

 checkLoadEnoughtOfflineData(idcheck) {
       return dbOffline.checkPageTable.where("idCheck").equals(idcheck).count();
    }

p/s：我正在使用 Google Chorm 62。

我假设您的调试器在此位置中断。这是一段故意破坏 "strict" 模式规则以生成错误的代码，以便可以从产生的错误中选择调用堆栈。如果您可以在调试器设置中忽略此错误类型，Chromium 调试器将不再烦扰您。它只会在 Dexie.debug === true 时发生（这是从 localhost 提供的站点的默认设置）。您在控制台日志中获得的功能是未处理拒绝的异步堆栈跟踪。您可以通过设置 Dexie.debug = false.

明确关闭它

来源看起来像这样：

export function getErrorWithStack() {
    "use strict";
    if (NEEDS_THROW_FOR_STACK) try {
        // Doing something naughty in strict mode here to trigger a specific error
        // that can be explicitely ignored in debugger's exception settings.
        // If we'd just throw new Error() here, IE's debugger's exception settings
        // will just consider it as "exception thrown by javascript code" which is
        // something you wouldn't want it to ignore.
        getErrorWithStack.arguments;
        throw new Error(); // Fallback if above line don't throw.
    } catch(e) {
        return e;
    }
    return new Error();
}
