【问题讨论】：

我在为 Tag npm 安装 ngx-chips 时遇到了同样的问题。现在我也不能编译并得到同样的问题 【参考方案1】：

对于metronic-angular 6.1.8，我花了8个小时，但我解决了。

已删除 package-lock.json 删除了 node_modules 文件夹 npm 安装

如果你执行ng serve收到TS1086错误，别担心...

现在启动：

npm i ngx-daterangepicker-material@2.2.0 npm i moment@2.18.1

重新启动`ng服务享受！ ;)

第一个解决方案解决了开发部分，但是在部署过程中出现了问题。最终的解决方案是：

已删除 package-lock.json 删除了 node_modules 文件夹 在 package.json 中删除 (^) 库 ngx-daterangepicker-material ("ngx-daterangepicker-material": "^2.1.11" -> "ngx-daterangepicker-material": "2.1.11") 将版本时刻从 ^2.24.0 增加到 2.25.3（删除 ^, "moment": "^2.24.0" -> "moment": "2.25.3",

现在一切正常... ng serve 和 yarn build。 ;)

我不敢相信我正在寻找的答案来自你 Pasquale！在***上随机选择的答案在这里相遇真是令人难以置信！无论如何，它对我有用，非常感谢，希望尽快收到您的来信！ 这个答案为我节省了数小时和数小时的搜索时间！【参考方案2】：

我通过以下两个步骤解决了这个问题

    首先从package.json中删除"ngx-daterangepicker-material": "^2.2.1"

    运行npm i ngx-daterangepicker-material@2.2.0

    “服务”

编译成功

【讨论】：

【参考方案3】：

我刚刚通过以下步骤解决了这个问题

    首先，从项目文件夹中删除 node_modules 文件夹

    在你的 package.json 中替换上面的 ngx-daterangepicker-material 版本 2.2.1到2.1.9，喜欢

删除 -> "ngx-daterangepicker-material": "^2.2.1",

添加 -> "ngx-daterangepicker-material": "^2.1.9",

    在终端运行 npm install 命令然后编译

编译成功

【讨论】：

奇怪的是这解决了这个问题。对我来说，这实际上也解决了这个问题，但我无法解释如何......【参考方案4】：

要解决此问题，我们必须检查您项目中使用的angular version。根据角度版本，我们必须更新package.json 中的ngx-daterangepicker-material 库。

检查以下内容，为您的 Angular 项目找到合适的库版本：

版本：

Angular      ngx-daterangepicker-material
>=9.0.0      v2.3.x and v3.x
<9.0.0       v2.2.x and below

参考： https://www.npmjs.com/package/ngx-daterangepicker-material

如果您在正常的"ng --prod" 中遇到javascript heap out of memory 问题，请运行以下评论以进行产品构建：

node --max_old_space_size=8192 node_modules/@angular/cli/bin/ng build client --prod

【讨论】：

更换版本问题依旧 请在 package.json 更改完成后执行“npm install”并检查角度版本是否小于 9 使用“ngx-daterangepicker-material”版本 2.2.0 并检查构建命令. 解决我的问题的答案已经出来了，在 pasquale carucci 的解释中。谢谢【参考方案5】：

您好，我也有同样的问题，但我尝试更改版本，但不起作用

【参考方案6】：

我尝试了上述所有建议的解决方案，但它们并没有为我解决问题。 但是，我通过简单地更改包版本解决了这个问题：

“ngx-daterangepicker-material”：“2.1.9”

然后 - 删除 node_modules 文件夹 - npm 安装 - ng服务工作 - ng build --prod --aot=true 也有效

【讨论】：

【参考方案7】：

    首先从 package.json 中删除 "ngx-daterangepicker-material": "^2.2.1"

    运行“npm i ngx-daterangepicker-material@2.2.0”
