Question

尝试安装Xcode 3.2.5时。在OS X El Capitan 10.11.5上，它失败并显示错误消息：

发生了未知的安装错误。安装程序遇到导致安装失败的错误。请与软件制造商联系以获取帮助。

我尝试使用GUI安装程序并使用命令行安装它：

cd / Applications sudo installer -pkg / Volumes / Xcode \ and \ iOS \ SDK / Xcode \ and \ iOS \ SDK.mpkg -target / -allowUntrusted -verbose -lang en

两者都失败了......

那么我该怎样才能安装这个旧的Xcode版本？

您可以尝试以下选项

public class MyClass
{
  public virtual IAdapter Adapter {get;set;}
  public MyClass(IAdapter adapter)
  {
    Adapter = adapter;
  }
}

var adapter = new Mock<IAdapter>();
adapter.Setup(a => a.WaitForDigit()).Returns(1);
var myClass = new MyClass(adapter.Object); //throws exception

System.ArgumentException: Constant does not match the defined type.

如果安装在OSX上，则卸载新版本的Xcode

OSX上的Xcode 3.2.5 El Capitan 10.11.5
