Question

我正在尝试在Windows 7上安装libbzip2。（实际上我想安装wp2txt包，但似乎需要libbzip2）。我按照Alex的建议安装了“Bzip2 for Windows”。但我得到以下错误。

C:\Users\John>gem install bzip2-ruby -- --with-bz2-include="C:\Program Files (x86)\GnuWin32\include" -- --with-bz2-lib="C:\Program Files (x86)\GnuWin32\lib"
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing bzip2-ruby:
        ERROR: Failed to build gem native extension.

        C:/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb --with-bz2-include=C:\Program Files (x86)\GnuWin32\include -- --with-bz2-lib=C:\Program Files (x86)\GnuWin32\lib

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:

        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib
        --with-make-prog
        --without-make-prog
        --srcdir=.
        --curdir
        --ruby=C:/RailsInstaller/Ruby1.9.3/bin/ruby
        --with-bz2-dir
        --without-bz2-dir
        --with-bz2-include=${bz2-dir}/include
        --with-bz2-lib=${bz2-dir}/lib
        --with-bz2lib
        --without-bz2lib
libbz2 not found, maybe try manually specifying --with-bz2-dir to find it?


Gem files will remain installed in C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bzip2-ruby-0.2.7 for inspection.

有几个问题。

1）您需要安装bzip2库。从Bzip2 for Windows二进制文件下载压缩库。将它们解压缩到某个目录，例如C：\ GnuWin32 \ bzip2-1.0.5-bin。 lib subdir应该包含libbz2.a，libbz2.def，libbz2.dll.a。应将此路径（C：\ GnuWin32 \ bzip2-1.0.5-bin \ lib）提供给--with-bz2-lib。

2）根据作者github.com/brianmario（版本h不存在），包bzip2-ruby似乎还有一个未修复的错误。所以你可以按照他的建议安装bzip2-ruby-rb20。

3）现在安装bzip2-ruby-rb20，为bzip2提供include和library dirs（安装在1中）：

gem install bzip2-ruby-rb20 -- --with-bz2-include="C:\GnuWin32\bzip2-1.0.5-bin\include" -- --with-bz2-lib="C:\GnuWin32\bzip2-1.0.5-bin\lib"

应该完成：“1 gem安装”

在Windows上安装libbzip2
