xcode - clang 前端命令失败，退出代码为 70(使用 -v 查看调用)

Question

在为我的 Meteor (cordova) 应用程序生成存档时，XCode 开始出现此错误。我没有对应用程序源代码进行任何更改。

关于类似错误的其他问题，如 this one，通过干净的构建、干净的 npm install 等来回答。对我来说没有任何效果。当执行 git clone 并从另一台计算机上的源构建时，甚至会发生此问题。

完整的错误信息是:

%struct.GPBObjcClass_t* @"OBJC_CLASS_$_GPBOption"

Answer 1

最终，我通过将 XCode 从 10.1 更新到 11.3.1(这是在我的 Mojave 上运行的最新版本)解决了这个问题。

这个答案帮助我更新:How to download Xcode DMG or XIP file?

(在 Firefox 上下载不顺利，但 Chrome 下载正常。)
