Answer 1

您是否尝试检查package.json？或者尝试执行npm i？还是tns install？

Answer 2

我认为有两点意见：

好像你没有跟随package.json安装它，因为它可以一起安装。 https://docs.nativescript.org/start/quick-setup
如果此模块存在，您应该在× Component tns-core-modules is not installed. × Component tns-android is not installed. × Component tns-ios is not installed.内查看：

npm ls <module-name>

您还要检查这一点：<module-name>，其中this.http.get('http://example.com/date.php') .subscribe((data:any[]) => { //<--say that you received an array this.posts = data; //Here filter is filter of an ARRAY, not Rxjs this.postsfilter = data.filter(item => item.date == todayDate); });是要检查的模块。

如果有帮助，请告诉我。
