告诉 Jest 不要模拟 /moment(-timezone)?/ 不工作

Question

在任何时候调用 moment/moment.tz() 时遇到错误，TypeError: (0 , _moment2.default)(...).tz is not a function 被抛出。下面是我的玩笑配置，绝对路径已编辑。

我试过把玩笑告诉jest.dontMock() 和jest.unmock()，但无济于事。

我也试过require.requireActual()。

我只想模拟使用jest.mock() 指定每个测试（每个文件）的时刻。

什么可能导致这些问题？我不是在我的测试文件中的任何地方嘲笑或取消嘲笑时刻。我只是简单地使用 @vue/test-utils 来模拟整个计算属性，同时使用 moment 来解决这个问题。

您可以尝试直接在测试中导入它们。另外，我检查了问题和其他问题，似乎导入timezone实际上并没有将tz函数添加到moment，所以解决它的方法可能是：

import moment from "moment-timezone"
