我的应用程序运行正常，但在我为快速服务器安装了一些模块之后突然开始出现角度误差。安装完这些模块后如
"bcryptjs": "*",
"connect-flash": "*",
"cookie-parser": "^1.4.3",
"express-messages": "*",
"express-session": "*",
"express-validator": "*",
"passport": "*",
"passport-http": "*",
"passport-local": "*"
express server运行正常，但是当我没有添加或修改任何包时，为什么我在Angular中收到这些错误。我不认为它们是相关的，为什么我突然开始出现这些错误：

=============================================
我已经尝试过以下内容：
感谢您的帮助。
答案 0 :(得分：0)
经过一些调查后我才明白问题出现是因为我为Server安装了一些库。仔细安装模块后，我发现express-validator具有以下依赖关系：
`-- 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，express-validator添加了bluebird，这导致了打字稿的问题。 在我进一步研究之后，我明白我需要使用typescript“2.3.2”。因此，我还修改并安装了typescript版本“2.3.2”for angular。
现在我的问题得到了解决，但我仍有疑问。
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？它们是如何相关的？可能是一个微不足道的问题，但我缺乏这个概念。
提前感谢您的详细解答。
