Question

在尝试重新安装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。我要安装的gem是scrypt（版本1.2.1），它是authlogic的依赖项。

gem install scrypt -v = 1.2.1

返回以下错误：

ERROR:  Error installing scrypt:

Answer 1

安装command line tools for 10.13可以解决此问题。

Answer 2

对于最新版本的macOS，似乎已弃用并删除了i386体系结构。假设您无法升级scrypt版本（这可能是最好的选择），仍然至少有两个选项可能对您有用。

使用docker映像。我刚刚使用ruby:2.5.3-slim进行了测试，而您只需要运行apt-get update && apt-get build-essential && gem install scrypt -v 1.2.1
下载包含i386架构的旧版SDK，并将其安装在系统上。 This包含一些可能有用的链接和信息（尽管不是特定于Rails的）

Answer 3

我遇到了这个确切的问题。

我正在运行Mojave（10.14.4）和XCode命令行工具的10.2版，并且在运行gem install scrypt -v 1.2.1时，遇到了与上述完全相同的错误。

解决方案是安装以下软件包：/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg（如Can't compile C program on a Mac after upgrade to Mojave中所述）。问题的根源显然是在此过程中的某个位置（捆绑程序？scrypt？），人们期望可以在/usr/include中找到头文件。最新版本的XCode不会将头文件放置在该位置，但是运行包会将其放置在该位置（如the XCode release notes中所述）

Answer 4

我尝试了给出的所有答案版本，但并不能完全为我完成工作。然后，以下步骤对我有用。

首先检查头文件是否存在。

ls /usr/include
ls: /usr/include: No such file or directory

由于没有标题，我删除了this answer中给出的CommandLineTools

sudo rm -rf /Library/Developer/CommandLineTools

更新xcode并安装macOS_SDK_headers_for_macOS_10.14.pkg

xcode-select --install
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

当我这样做时，现在头文件存在 ls /usr/include

gem install scrypt -v 1.2.1

i386 Arch错误与OS X Mojave安装旧的scrypt gem版本
