“未找到中央目录结尾签名."安装 Xcode 8 beta xip 文件时 [英] "End-of-central-directory signature not found." when installing Xcode 8 beta xip file

问题描述

我已经下载了 Xcode 8 beta .xip 文件.我无法解压缩.打开文件只是在那里停留了几个小时说正在验证..."

I've download the Xcode 8 beta .xip file. I cannot unzip. Opening the file just sits there for hours saying "Verifying..."

如果我从命令行尝试，我会得到以下...

If I try from command line I get the following...

Downloads unzip Xcode_8_beta.xip 
Archive:  Xcode_8_beta.xip
  End-of-central-directory signature not found.  Either this file 
  is not a zipfile, or it constitutes one disk of a multi-part archive.        

  In the latter case the central directory and zipfile comment will be
  found on the last disk(s) of this archive. unzip:  cannot find 
  zipfile directory in one of Xcode_8_beta.xip or Xcode_8_beta.xip.zip, 
  and cannot find Xcode_8_beta.xip.ZIP, period.

推荐答案

XIP 文件(就地提取)只是一个特殊的存档，用于验证 Apple 的取消存档.在 2014 款 MacBook Pro i7 上，Xcode 8 二进制文件的提取时间超过 30 分钟.如果在接近一个小时后文件没有取得太大进展，请重新下载存档并再次尝试解压缩.

The XIP file (extract in place) is just a special archive that verifies the unarchive with Apple. On a 2014 MacBook Pro i7 the Xcode 8 binary took over 30 minutes to extract. If the file is not making much progress after close to an hour, re-download the archive and try extracting again.

此外，Xcode 8.0 beta 需要运行 macOS 10.11.4 或更高版本的 Mac.确保您的系统版本受支持.

Additionally, Xcode 8.0 beta requires a Mac running macOS 10.11.4 or later. Make sure your system version is supported.

Xcode 8 Beta 2 注意:安装 Beta 2 需要 macOS 10.11.5 或更高版本.

Xcode 8 Beta 2 note: macOS 10.11.5 or later is required to install Beta 2.
