Question

我有一个Angualr 6项目，我试图运行以下命令npm run build。如何显示以下错误消息。

ERROR in node_modules/rxjs/internal/symbol/observable.d.ts(4,9): error TS2687: All declarations of 'observable' must have identical modifiers.

node_modules/@types/node/index.d.ts(167,14): error TS2687: All declarations of 'observable' must have identical modifiers.

Angular Version

忘记提及只发生在我的码头图片中。

docker build -t $IMG --build-arg env=production .

# Stage 0 - Pre-requisite: Based On Node.js to BUILD and compile Demo Angular App.

FROM node:8.11.2 as node

ARG env

Answer 1

将@ types / node更新为10.3.0后出现同样的问题。降级到10.1.4版后，一切正常。我认为rxjs必须更新才能使用最新的@ types / node版本。所以目前，只需使用旧版本：

Animal

更新：已完成对RxJS的修复 - ＆gt; https://github.com/ReactiveX/rxjs/pull/3773。现在他们只需要合并更改并发布新版本。

Answer 2

我在使用较低版本的节点时遇到了同样的问题。

修复它的目的是：

转到有问题的 observable.d.ts，在我的情况下是： node_modules/angular-datatables/node_modules/rxjs/internal/symbol/observable.d.ts
改变：

declare global {
    interface SymbolConstructor {
        readonly observable: symbol;
    }
}

到：

declare global {
    interface SymbolConstructor {
        observable: symbol;
    }
}

我想反之亦然。

错误TS2687：所有可观察的声明＆＃39;必须有相同的修饰符
