Question

我试图在Windows 8.1计算机上运行rails应用程序，但我需要json gem version 1.8.1。我目前有json 1.7.7。 Bundle install会返回一个错误，并要求我确保＆＃34; gem install json -v 1.8.1＆＃34;成功。运行该命令返回

E:\rails_projects\bookit>gem install json -v 1.8.2
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing json:
    ERROR: Failed to build gem native extension.

我将DevKit路径添加到我的环境变量列表中。我觉得奇怪的是我遇到了DevKit的问题，因为green_shoes安装并且工作正常，它需要DevKit。我错过了什么？

注意：我正在使用Ruby 2.0.0,64位，以及rubyinstaller.org推荐的相应DevKit

Answer 1

这是你的错误：

make: x86_64-w64-mingw32-gcc: Command not found

-

导致错误的原因是您的计算机上找不到gcc/gc++ compiler。

您应该refer to this page了解更多相关信息。

您应该download this build kit，安装它，然后运行以下内容：

set PATH=c:/path/to/your/mingw64/installation;%PATH%

然后再次执行构建 - 它应该可以工作。

如何让json gem 1.7.7更新？
