Question

我正在尝试为Angular应用程序提供服务，但是我从“ ngx-mqtt”得到此依赖项错误：“ ^ 6.6.0”。我的本地CLI是6.2.9版本。我正在尝试更改此依赖项的版本，但是仍然出现此错误。我只是不知道为什么会这样。

./ node_modules / ngx-mqtt / src / mqtt.service.js 390：34-55中的警告   “在'@ angular / core'中找不到导出'ɵɵdefineInjectable'（导入为'i0'）

./ node_modules / ngx-mqtt / src / mqtt.service.js 390中的警告：126-137   “在'@ angular / core'中找不到导出'ɵɵinject'（导入为'i0'）

./ node_modules / ngx-mqtt / src / mqtt.service.js 390：161-172中的警告   “在'@ angular / core'中找不到导出'ɵɵinject'（导入为'i0'）

这些是我来自package.json的主要依赖项

        "@angular/animations": "^6.1.7",
        "@angular/cdk": "^6.4.7",

从^中删除字符"ngx-mqtt": "^6.6.0"可解决此问题。

Angular编译警告：“在'@ angular / core'中未找到export'ɵɵdefineInjectable'
