Question

我似乎无法使用Ruby 1.9.3p194在我的Windows 7计算机上运行捆绑更新。我也安装了最新的DevKit。 bundle抱怨缺少make命令，我在我的硬盘上找不到make（我搜索过）。我如何让它工作？

An error occured while installing json (1.7.5), and Bundler cannot continue.
Make sure that `gem install json -v '1.7.5'` succeeds before bundling.

Answer 1

DevKit目录中的

ruby dk.rb install --force可以解决问题。

Answer 2

有些宝石需要编译，json宝石就是这种情况。

您可以通过安装RubyInstaller的DevKit解决大多数宝石的编译问题，可从downloads page

获取

下载完成后，请关注RubyInstaller维基页面的installation instructions。

安装完成后，打开一个新的命令提示符并尝试再次安装有问题的gem：

gem install json

它应该成功。

这是考虑DevKit已正确安装。正如RubyInstaller邮件列表中所讨论的，您可以强制安装DevKit：

ruby dk.rb install --force

在DevKit目录中。

由于json 1.7.5，无法运行bundle更新
