【中文标题】Angular 10:路径映射在导入时在 VSCode 中显示错误【英文标题】:Angular 10: Path Mapping shows error in VSCode when import 【发布时间】:2020-10-23 17:44:05 【问题描述】:所以我将 Angular 8.2(项目模板)中的一个项目更新到版本 10,并按照 https://update.angular.io/ 的说明进行操作,一切正常,但是当实施路径映射时,痛苦开始了,我到处都收到这个错误:
Cannot find module '@environments/environment' or its corresponding type declarations.ts(2307)
并且此错误适用于路径中声明的@environments和@modules,其他没有显示任何错误,因为它们没有被使用。 p>
目前使用ng build时项目正在正确构建,尚未尝试ng build --prod,没有出现错误但Visual Studio Code( v1.46.1) 正在向我显示有错误的导入,这是我拥有的:

这里还有一张我的项目组织方式的图片
还有一件非常奇怪的事情发生,例如我有 2 个服务(我在每个服务中都有问题)一个 CityService(正在使用)和 ColorService(未使用),CityService 没有显示任何错误,我可以访问模块定义(F12),但在具有相同结构的 ColorService 中存在问题出现并显示为红色。
【问题讨论】:
你有没有解决这个问题我也面临同样的问题。 【参考方案1】:我通过以下更改解决了这个问题。
只需更改tsconfig.app.json
和tsconfi.app.json
中extends("extends": "../tsconfig.json"
,)的路径
将tsconfig.base.json
中的所有代码复制到tsconfig.json
文件中。
下面是tsconfig.json
文件的代码。

A) 如果您有一个活动的 ng serve,请重新启动 ng serve
CTRL + C
ng serve
B) 如果您没有有效的 ng 服务,请执行以下操作:
Command + Shift + P
Search for "TypeScript: Restart TS Server"
Hit enter
【讨论】:
我重新启动了 TS Server 并没有帮助。但请记住,一定要重新启动 VS Code。现在可以了,谢谢!【参考方案2】:请尝试更改
'环境/环境'
到
'src/environments/environment'
【讨论】:
仍然无法正常工作,这没有任何改变。 一直在尝试,但似乎是 Visual Studio Code 问题以上是关于Angular 10:路径映射在导入时在 VSCode 中显示错误的主要内容,如果未能解决你的问题,请参考以下文章
