Xcode 链接器错误：找不到文件

Question

我目前在我的 Xcode 项目中使用 cocoapods 为我的应用程序创建一个 google 登录按钮，在再次完成教程步骤后，构建时仍然出现错误。以下是构建时显示的错误消息。希望能帮助您解决此问题。

短错误消息（在控制台错误消息的末尾）

ld: file not found: /Users/tarunaarora/Desktop/GunnOracleApplication/Pods/GoogleUtilities/Libraries/libGTM_NSData+zlib_external.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)

这就是我的 Xcode Project Podfile 文档和 Pod 的显示方式：

我目前也在使用 Xcode 8.2 beta

编辑：

最后我包含了我为解决问题所做的解决方案，因为大多数其他解决方案都没有奏效。随意查看解决方案。

Answer 1

1. 在您的 podfile 中，注意 ` 到 ' 之间的区别。

2. 纠正此问题后，您可以：

   一个。清理项目（产品 -> 清理）

   b.关闭 XCode

   c。运行pod install

   d。打开yourProjectName.xcworkspace

Answer 2

打开构建设置 转到框架搜索路径

这个继承的&项目目录会导致Pods自动检测，不会再给你造成问题。尝试这样做，它会自动检测 pod。这可能会有所帮助

Answer 3

您应该更改scheme name。删除旧的scheme 并添加新的！

您可以通过转到Product > Scheme > Manage Schemes 并按"Autocreate Schemes Now" 为您的目标自动创建方案

参考：this so post

Answer 4

在阅读了上面的解决方案后，没有一个对我有用，所以我开始自己试验，看看是否有其他解决方案可以解决这个问题。

以下是导致我解决此问题的步骤：

1. 重新创建项目。 （我复制了我需要的文件，省略了我不需要的，所以我只复制了 Main.storyboard 和 Assets 文件）

2. 正确安装 Pod。 （我再次浏览了我正在使用的教程，并确保我安装的 Pod 与他安装的完全相同。项目构建没有任何错误。）

3. 对 ViewController.swift 和 Appdelegate 文件进行编码。 （我又看了一遍教程，认真地重写了他在教程中写的代码）

4. 构建项目并了解错误。 （我使用正确的方案设置构建了项目，然后我检查了控制台中显示的所有错误，并更正了它们。）我遇到的所有错误，在教程中都有解决方案。

5. 现在项目已经成功创建，没有任何错误！
