在您的 Gemfile 中列出的或本机上可用的任何 gem 源中找不到 gem 'wdm (>= 0.1.0) x64-mingw32'

Question

当我在 Git Bash 上运行 Jekyll serve 时，我收到以下警告：

Please add the following to your Gemfile to avoid polling for changes:
gem 'wdm', '>= 0.1.0' if Gem.win_platform?

添加 Gemfile 后，我收到另一条错误消息。

Could not find gem 'wdm (>= 0.1.0) x64-mingw32' in any of the gem sources
listed in your Gemfile or available on this machine.

我尝试安装 Ruby Devkit 来解决此问题，但最终只收到以下错误消息。

$ ruby dk.rb install
[INFO] Skipping existing gem override for 'C:/Ruby200-x64'
[WARN] Skipping existing DevKit helper library for 'C:/Ruby200-x64'

$ gem install json --platform=ruby
ERROR: Error installing json:
The 'json' native gem requires installed build tools.

Please update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions
at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'

Answer 1

您需要在将wdm gem 添加到您的Gemfile 后运行bundle install 才能下载它。

Answer 2

好像你之前安装过devkit，跳过新安装，试试

ruby dk.rb install --force
