我已经尝试过研究，它是一个源自 moment-js 的错误，但我没有使用该模块，也没有安装它。

可能是什么问题？

【问题讨论】：

如果不使用moment，则运行yarn remove moment或npm uninstall moment
@Redline 谢谢。我已经尝试过了，但它对我没有用
@KinaraNyakaru 试试这个。删除 node-modules 文件夹，我的意思是删除它然后进行 npm 安装，看看它是否有效
@ImranRafiqRather 抱歉，我忘了说明我之前尝试过，但没有成功
@KinaraNyakaru 此错误是最新错误，由于时刻库中的更新而出现。按照答案中提供的步骤解决它。如果有帮助，请评分:)

【解决方案1】：

之所以会这样，是因为moment发布了2.24.0到2.25.0的新版本

执行以下步骤来解决此问题：

第 1 步： 更改版本（在您的情况下，只需将 "moment":"2.24.0" 添加到您的依赖项中你的 package.json 因为我没有在你的 package.json 中看到它）

"moment": "2.24.0",
"moment-timezone": "^0.5.28",

第 2 步：如果您使用的是 yarn，请像这样在您的 package.json 文件中添加分辨率

"dependencies" {
"moment": "2.24.0",
"moment-timezone": "^0.5.28"
},
"resolutions": {
"moment": "2.24.0"
},

【讨论】：

似乎 2.25.2 版本正在解决这个问题。因此不再需要降级到 2.24.0。
@Matt Weber：到目前为止，降级已经为许多开发人员工作。 5 月 4 日发布了 2.25.2 版本，但下载量仍然很少。 nuget.org/packages/Moment.js

【解决方案2】：

package.json 的变化：

"moment": "2.25.1",

到

"moment": "2.24.0",

然后在终端上运行：npm install

【讨论】：

【解决方案3】：

Moment 发布打破应用程序的新版本，

在你的情况下，package.json 中没有任何时刻，如果你只是将它添加到你的包中

moment: "2.24.0"

并运行 npm install 它将添加这个时刻包并解决您的问题，

否则你可以试试这个cammand

npm install --save --save-exact moment@2.24.0

它会自动将此包添加到具有此特定版本的 package.json 中

我希望这对你有用

【解决方案4】：

New moment 2.25.x 版本已经发布，最新版本应该可以解决这个问题。

似乎2.25.2 版本正在解决这个问题。因此不再需要降级到 2.24.0。

这应该是评论，而不是答案
