Question

我正在使用使用authlogic的Rails应用程序。包含scrypt加密算法（尽管未使用）。我在Mac上发现了这个错误。我如何重新开始？

为什么i386被认为是平台？我真的不在乎scrypt - 我怎么能绕过这个？

ld: in '/usr/local/lib/libunwind.dylib', file was built for x86_64 which is not the architecture being linked (i386): /usr/local/lib/libunwind.dylib for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
rake aborted!

Gem files will remain installed in /Users/jt/.rvm/gems/ruby-2.1.2@ssui/gems/scrypt-3.0.5 for inspection.
Results logged to /Users/jt/.rvm/gems/ruby-2.1.2@ssui/extensions/x86_64-darwin-17/2.1.0/scrypt-3.0.5/gem_make.out

An error occurred while installing scrypt (3.0.5), and Bundler cannot continue.
Make sure that `gem install scrypt -v '3.0.5'` succeeds before bundling.

In Gemfile:
  authlogic was resolved to 3.6.0, which depends on
    scrypt

Answer 1

`bundle update scrypt`

刚刚发布的scrypt gem 3.0.6解决了此问题。它不在变更日志中，但您可以阅读PR：https://github.com/pbhogan/scrypt/pull/72

Answer 2

scrypt gem版本3.0.5导致问题。

我正在检查他们的releases，但找不到3.0.5。最新版本为3.0.3

jvillian可能是对的。解决方案可能是使用wtfiwtz建议：

从-arch i386和/Users/<username>/.rvm/gems/ruby-2.3.1/gems/scrypt-2.0.2/ext/scrypt/Rakefile删除对/Users/<username>/.rvm/gems/ruby-2.3.1/gems/scrypt-2.0.2/Rakefile的引用，然后执行以下操作：

cp -R /Users/<username>/.rvm/gems/ruby-2.3.1/gems/scrypt-2.0.2/ ~/Code/scrypt
cd ~/Code/scrypt
gem build scrypt.gemspec
gem install --local scrypt-2.0.2.gem

我还必须在scrypt.gemspec
中注明关于签名密钥的一行

通过检查the scrypt Rakefile sourcecode，我发现了可能触发错误的代码。这是一个特定于mac的问题（if t.platform.mac?）。

desc "FFI compiler"
namespace "ffi-compiler" do
  FFI::Compiler::CompileTask.new('ext/scrypt/scrypt_ext') do |t|
    t.cflags << "-Wall -std=c99"
    t.cflags << "-msse -msse2" if t.platform.arch.include? "86"
    t.cflags << "-D_GNU_SOURCE=1" if RbConfig::CONFIG["host_os"].downcase =~ /mingw/
    t.cflags << "-D_POSIX_C_SOURCE=199309L" if RbConfig::CONFIG['host_os'].downcase =~ /linux/
    t.cflags << "-arch x86_64 -arch i386" if t.platform.mac?
    t.ldflags << "-arch x86_64 -arch i386" if t.platform.mac?

    t.add_define 'WINDOWS_OS' if FFI::Platform.windows?
  end
end

scrypt无法通过authologic安装
