CocoaPods: App.xcworkspace不存在

Question

事情就是这样发生的：

$ pod lib lint

 -> MXKit (5.2.2)
    - ERROR | [iOS] xcodebuild: Returned an unsuccessful exit code. You can use `--verbose` for more information.
    - NOTE  | [iOS] xcodebuild:  xcodebuild: error: 'App.xcworkspace' does not exist.

[!] MXKit did not pass validation, due to 1 error.
You can use the `--no-clean` option to inspect any issue.

我在用：

• CocoaPods 1.0.1
• Ruby 2.2.2
• Xcode 8.0
• OS X 10.12

通过添加--verbose选项：

$ pod lib lint --verbose

今天我安装了一个带有Parallels 12的新系统(macOS塞拉利昂10.12)，并且：

• 下载Xcode 8(并安装组件)
• 安装rvm 1.27.0 (最新)
• 更新创业板至2.6.6
• 安装CocoaPods 1.0.1

但是pod lib lint和pod trunk push命令仍然不能工作。

:(

Answer 1

sudo gem install cocoapods --pre

当我将cocoapods更新到1.1.0.rc.2时，错误就消失了。希望这能帮到你。

Answer 2

安装新版本的Xcode后尝试sudo xcode-select -s /Applications/Xcode8.0.app/Contents/Developer/
