使用 OS X Mojave 安装旧的 scrypt gem 版本时出现 i386 arch 错误 [英] i386 arch error installing old scrypt gem version with OS X Mojave

问题描述

在全新安装 OS X 10.14 Mojave 和 XCode 命令行工具后，我正在尝试为旧项目安装旧的 gem 版本.我尝试安装的 gem 是 scrypt，版本 1.2.1，它是 authlogic 的依赖项.

I'm trying to install an old gem version for an old project after a fresh install of OS X 10.14 Mojave and XCode Command Line Tools. The gem I'm trying to install is scrypt, version 1.2.1, which is a dependency of authlogic.

gem install scrypt -v=1.2.1

gem install scrypt -v=1.2.1

返回以下错误:

Building native extensions. This could take a while...
ERROR:  Error installing scrypt:

推荐答案

我遇到了这个确切的问题.

I was experiencing this exact problem.

我正在运行 Mojave (10.14.4) 和 10.2 版的 XCode 命令行工具，并且在运行 gem install scrypt -v 1.2.1 时，我得到了完全相同的错误如上所述.

I'm running Mojave (10.14.4) and Version 10.2 of the XCode Command Line Tools, and when running gem install scrypt -v 1.2.1, I was getting the exact same error as described above.

解决方案是安装这个包:/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg(如升级到 Mojave 后无法在 Mac 上编译 C 程序).显然，问题的根源在于在这个过程中的某个地方(bundler?scrypt?)期望头文件可以在 /usr/include 中找到.最新版本的 XCode 不会将头文件放在该位置，但运行包会将它们放在那里(如 XCode 发行说明)

The solution was to install this package: /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg (as described in Can't compile C program on a Mac after upgrade to Mojave). Apparently the root of the issue was that somewhere in this process (bundler? scrypt?) there was an expectation that header files could be found in /usr/include. The latest version of XCode does not place header files in that location, but running the package places them there (as documented in the XCode release notes)
