我正在 Windows XP 上为 Rails 应用程序设置测试代理。
为了强制代理之间的一致性,我通过带有 Cygwin 的 RVM 的 Bundler 安装它。
以下是在项目目录中运行 bundle install 的结果(编辑:请注意,运行 gem install bcrypt-ruby 会产生相同的输出):
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing bcrypt-ruby (3.0.1), and Bundler cannot continue.
Make sure that `gem install bcrypt-ruby -v '3.0.1'` succeeds before bundling.
安装了 cygwin gcc 包:
$ whereis gcc
gcc: /bin/gcc.exe /usr/bin/gcc.exe /lib/gcc /usr/lib/gcc /cygdrive/e/Cygwin/bin/gcc.exe /usr/share/man/man1/gcc.1.gz
$ gcc -v
Using built-in specs.

和 bcrypt 一样:
$ whereis bcrypt
bcrypt: /bin/bcrypt.exe /usr/bin/bcrypt.exe /cygdrive/e/Cygwin/bin/bcrypt.exe /usr/share/man/man1/bcrypt.1.gz
bcrypt -v
bcrypt: unknown option -- v
Usage is: /bin/bcrypt -[orc][-sN] file1 file2..
-o Write output to standard out
-r Do NOT remove input files after processing
-c Do NOT compress files before encryption
-sN How many times to overwrite input files with random data
进一步研究的结果:
环境
rvm use system
(在我的情况下是 1.9.3-p286)允许 bcrypt-ruby 顺利安装
通过 rvm 安装 1.9.3-p286 并设置
rvm use 1.9.3-p286
导致相同的(禁止 ruby 版本)错误消息。
在 Mac OS X 上安装可以在众多开发人员站和多个 Mac 代理上顺利运行。
所有这些都表明该错误位于 rvm 与 cygwin 的交集处。
我已经尝试了我能想到的一切。任何帮助将不胜感激。
谢谢
