bzip2-ruby Windows安装

Question

我试图在Windows 7 x64上安装bzip2-ruby gem。现在我不知道这个gem是否可以在64位Windows上运行。我确实安装了安装到C：\ Program Files（x86）\ GnuWin32的bzip2。

当我去安装，运行以下命令：

gem install bzip2-ruby -- --with-bz2-dir="C:\Program Files (x86)\GnuWin32\" 

当运行我得到以下输出：

Temporarily enhancing PATH to include DevKit... 
Building native extensions. This could take a while... 
*** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers. Check the mkmf.log file for more 
details. You may need configuration options. 

Provided configuration options: 
     --with-opt-dir 
     --without-opt-dir 
     --with-opt-include 
     --without-opt-include=${opt-dir}/include 
     --with-opt-lib 
     --without-opt-lib=${opt-dir}/lib

     --without-bz2-include=${bz2-dir}/include 
     --with-bz2-lib 
     --without-bz2-lib=${bz2-dir}/lib 
     --with-bz2lib 
     --without-bz2lib

checking for bzlib.h... no 
checking for BZ2_bzWriteOpen() in -lbz2... no 
libbz2 not found, maybe try manually specifying --with-bz2-dir to find it? 

Gem files will remain installed in C:/Ruby193/lib/ruby/gems/1.9.1/gems/bzip2-ruby-0.2.7 for inspection. 
Results logged to C:/Ruby193/lib/ruby/gems/1.9.1/gems/bzip2-ruby-0.2.7/ext/gem_make.out 

我可以验证libbz2.a，libbz2。 def，libbz2.dll.a文件存在于上面路径的lib文件夹中。

我是否在运行命令来指定lib文件夹时错过了一个额外的选项？

谢谢！

对于GCC（捆绑在RubyInstaller DevKit中的编译器）正常工作，需要使用路径而不使用空格。

您提供的extconf选项具有空格路径。请将bzip2中的lib，include和bin文件夹重新定位到无空格的目录中，然后重试。

此外，您需要同时具有两个标头（在include目录中找到）和导入库（在lib目录中找到）以使扩展编译生效。

希望有所帮助。
