试图安装libv8，“无法构建gem原生扩展” [英] Attempting to install libv8, "failed to build gem native extension"

问题描述

我使用W7 64bit。简单地说，当我输入时：

  C：\网站> gem install libv8 
  

我得到这个结果：

 暂时增强包括DevKit的路径... 
构建本机扩展。这可能需要一段时间... 
错误：安装libv8时出错：
错误：无法构建gem本机扩展。 
 
 C：/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb 
创建Makefile 
其中：no gmake in（我的PATH在这里，到目前为止因为我知道它应该包括我需要的一切）
 / usr / bin / env：python：没有这样的文件或目录
 C：\RailsInstaller\DevKit\bin\make.EXE： *** [out / Makefile.ia32]错误127 
使用编译器：C：\RailsInstaller\DevKit\mingw\bin\g ++ .EXE 
 GYP_GENERATORS = make \ 
 build / gyp / gyp --generator-output =outbuild / all.gyp \ 
 -Ibuild / standalone.gypi --depth =。 \ 
 -Dv8_target_arch = ia32 \ 
 -S.ia32 -Dhost_arch = ia32 
 
 
 Gem文件将保持安装在C：/RailsInstaller/Ruby1.9.3 /lib/ruby/gems/1.9 
 .1 / gems / libv8-3.11.8.3进行检查。 
记录到C的结果：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/libv8-3.1 
 1.8.3 / ext / libv8 / gem_make.out 
  

卸载并重新安装不起作用。

我是试图安装libv8，因为它是twitter-bootstrap-rails的依赖项。

编辑：正如我所说，我在Windows上，现在我意识到存在此错误中列出的文件路径为/ usr / bin / env。所以这很奇怪。

解决方案

解决方案是安装版本.0 / b

  gem install libv8 --version 3.11.8.0 
  

直到这是固定的，就像我经历过的那样，也是

I am using W7 64bit. Simply put, when I enter:

C:\Sites>gem install libv8

I get this result:

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...

Gem files will remain installed in C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9
.1/gems/libv8-3.11.8.3 for inspection.
Results logged to C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/libv8-3.1
1.8.3/ext/libv8/gem_make.out

Uninstalling and reinstalling does not work.

I'm trying to install libv8 because it's a dependency for twitter-bootstrap-rails.

EDIT: As I said, I'm on Windows, and I'm realizing now that there's a filepath listed in this error as /usr/bin/env. So that's weird.

解决方案

The solution is to install version .0

gem install libv8 --version 3.11.8.0

until this is fixed, as I experienced this, too
