我的应用程序运行良好，但在我为快速服务器安装了一些模块后突然开始出现这些 angular 错误。安装这些模块后，例如
"bcryptjs": "*",
"connect-flash": "*",
"cookie-parser": "^1.4.3",
"express-messages": "*",
"express-session": "*",
"express-validator": "*",
"passport": "*",
"passport-http": "*",
"passport-local": "*"
快速服务器运行良好，但是为什么当我没有添加或修改任何包时，我在 Angular 中收到这些错误。我不认为它们是相关的，那么为什么突然我开始出现这些错误：

=============================================
我已经尝试了以下方法：
- 删除了"node_modules"文件夹并使用"npm install"再次安装软件包
- 将"@types/节点"修改为最新版本
- 将"打字稿"修改为"*"、"2.3.0"、"^2.3">
感谢您的帮助。
经过一些调查，我明白出现问题是因为我已经为服务器安装了一些库。在仔细安装模块后，我开始知道表达式验证器具有以下依赖项：
`-- express-validator@3.2.1
+-- @types/bluebird@3.5.8
+-- @types/express@4.0.36
| +-- @types/express-serve-static-core@4.0.49
| | `-- @types/node@8.0.13
| `-- @types/serve-static@1.7.31
| `-- @types/mime@1.3.1
+-- bluebird@3.5.0
+-- lodash@4.17.4
`-- validator@6.2.1
因此，快递验证器添加了蓝鸟，这导致了打字稿的问题。 经过进一步的研究，我明白我需要使用打字稿"2.3.2"。因此，我还修改并安装了 angular 的打字稿版本"2.3.2"。
现在我的问题解决了，但我仍然有一个问题。
为什么客户端(Angular/Typescript(导致为Server(Express(安装的模块出现问题，因为它们都有自己的node_modules文件夹？它们有什么关系？也许这是一个微不足道的问题，但我缺乏这个概念。
提前感谢您的详细回答。
