我正在尝试构建一个使用 RxSwift 模块的项目，XCode 一直抱怨错误“没有这样的模块 RxSwift”...

我试过多次安装这个模块，在终端我在pod install之后收到以下消息

据我了解，RxSwift 已安装，为什么 Xcode 一直抱怨它？

我正在执行 .xcworkspace 文件..

提前感谢您的回答！

【问题讨论】：

对，应该已经将 RxSwift 添加到您的工作区，但您是否已将 RxSwift 框架添加到实际项目的目标（即作为嵌入式二进制和/或链接框架）？

我建议你做 pod 工具建议的事情。

How to remove CocoaPods from a project?

安装 pod 文件的简单步骤：

关闭 Xcode 项目

1.打开终端（Command + Space & type终端）

2.在终端设置你的项目路径。(cd Desktop/PodDemos)

3.终端输入命令：sudo gem install cocoapods

4.Command : pod init

5.转到项目的pod文件并添加要安装的pod（命令：打开podfile）

6.添加到 pod 文件中：pod 'RxSwift'

pod 'RxCocoa'

7.Command : Pod install

8.从终端打开你的项目 命令：打开 PodDemos.xcworkspace

或

转到项目文件夹并打开 PodDemos.xcworkspace
