使用 OS X Mojave 安装旧 scrypt gem 版本时出现 i386 arch 错误

Question

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

gem 安装 scrypt -v=1.2.1

Returns 出现如下错误：

ERROR:  Error installing scrypt:

Answer 1

最新版本的 macOS 似乎已弃用并删除了 i386 架构。假设您无法升级 scrypt 版本（这可能是最佳选择）

，至少还有 2 个选项可能适合您

使用 docker 图片。我刚用 ruby:2.5.3-slim 测试过，你只需要运行 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，并将其安装到您的系统上。 This 有一些可能有用的链接和信息（尽管不是 rails 特定的）

Answer 2

安装 command line tools for 10.13 为我解决了这个问题。

Answer 3

我确实遇到了这个问题。

我是运行 Mojave (10.14.4) 和 XCode 命令行工具的版本 10.2，当运行 gem install scrypt -v 1.2.1 时，我得到了与上述完全相同的错误。

解决方案是安装此软件包：/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). 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 中所述）

Answer 4

我尝试了给出的所有版本的答案，它并不完全适合我。然后以下步骤对我有用。

首先检查 header 个文件是否存在。

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

由于 header 不存在，我删除了 CommandLineTools，就像 this answer

中给出的那样

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

现在 header 文件在我做的时候出现了 ls /usr/include

gem install scrypt -v 1.2.1
