Question

在我的Ionic 3.9应用程序中，在浏览器中运行__WEBPACK_IMPORTED_MODULE_1_rxjs_Observable__.Observable.combineLatest is not a function时出现以下错误：ionic serve。

我遇到了插件错误，因此删除了node_modules，yarn.lock，并通过$ yarn install重新安装了所有依赖项。

ERROR TypeError: __WEBPACK_IMPORTED_MODULE_1_rxjs_Observable__.Observable.combineLatest is not a function
    at NgxErrorDirective.ngOnInit (ngxerror.directive.js:40)
    at checkAndUpdateDirectiveInline (core.js:12369)
    at checkAndUpdateNodeInline (core.js:13893)

这是我的配置：

$ ionic info

Ionic:

   ionic (Ionic CLI)  : 4.6.0
   Ionic Framework    : ionic-angular 3.9.2
   @ionic/app-scripts : 3.2.1

Cordova:

   cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms     : android 7.0.0, browser 5.0.4
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.2, (and 5 other plugins)

System:

   Android SDK Tools : 25.2.5 (/home/louisro/android-sdk-linux/)
   NodeJS            : v8.9.4 (/home/louisro/.nvm/versions/node/v8.9.4/bin/node)
   npm               : 5.6.0
   OS                : Linux 4.4

$ yarn install给出了以下内容：

$ yarn install
yarn install v1.12.3

Answer 1

好像有问题structure(list(individual = 1:9, stage = structure(c(2L, 2L, 2L, 2L, 2L, 3L, 1L, 1L, 1L), .Label = c("adult", "infant", "juvenile" ), class = "factor"), fate = structure(c(2L, 2L, 3L, 3L, 3L, 1L, 1L, 1L, 1L), .Label = c("adult", "infant", "juvenile"), class = "factor"), fertility = c(0L, 0L, 0L, 0L, 0L, 0L, 0L, 1L, 1L)), row.names = c(NA, -9L), class = "data.frame")。很难假设不看代码，但是如果您导入Observable，则更有可能也需要像这样导入CombineLatest

Observable.combineLatest

希望它能起作用。

Answer 2

yarn告诉您：您的对等依赖项不正确。

我看到您正在尝试安装需要@angular/fire@5.1.1的{{1}}软件包。这也意味着将所有@angular/common@>=6.0.0和@angular/*依赖项升级到6.0.0或更高版本。

您还应该注意，rxjs 6与以前的版本之间有一些重大更改（您的CombineLatest错误可能来自此处）。您还可以安装rxjs来保持代码不变。

希望有帮助。
