为什么显示“ld: framework not found Bolts”

Question

安装 facebook sdk 后，当我构建我的项目时，它显示：

ld: warning: directory not found for option '-F/Users/liyuanliu/Library/Developer/Xcode/DerivedData/c5-dsovqtraubbdgxbqrmiexjmlysxq/Build/Products/Debug-iphonesimulator/Bolts'
ld: warning: directory not found for option '-F/Users/liyuanliu/Library/Developer/Xcode/DerivedData/c5-dsovqtraubbdgxbqrmiexjmlysxq/Build/Products/Debug-iphonesimulator/FBSDKCoreKit'
ld: warning: directory not found for option '-F/Users/liyuanliu/Library/Developer/Xcode/DerivedData/c5-dsovqtraubbdgxbqrmiexjmlysxq/Build/Products/Debug-iphonesimulator/FBSDKLoginKit'
ld: warning: directory not found for option '-F/Users/liyuanliu/Library/Developer/Xcode/DerivedData/c5-dsovqtraubbdgxbqrmiexjmlysxq/Build/Products/Debug-iphonesimulator/FBSDKShareKit'
ld: framework not found Bolts
clang: error: linker command failed with exit code 1 (use -v to see invocation)

但是当我安装 facebook 和 bolts 时，它显示我安装成功：

pod install

以下是我的构建阶段图像：

在下面找不到螺栓框架图像

我找不到 FBXXXX.framework

添加框架后，它仍然存在：
