An error occurred while installing rake (11.2.2), and Bundler cannot continue.
Make sure that `gem install rake -v '11.2.2'` succeeds before bundling.

Answer 1

请按照以下说明进行操作，这将解决您的问题。

步骤很简单:

Step 1: Obtain the new trust certificate

我们需要下载AddTrustExternalCARoot-2048.pem .

使用上面的链接并将此文件放置/保存到您以后可以轻松找到的地方(例如您的桌面)。

重要提示:文件必须以 .pem 作为扩展名。 Chrome 等浏览器会尝试将其保存为纯文本文件。确保在下载后将文件名更改为包含 .pem。

Step 2: Locate RubyGems certificate directory in your installation

为了让我们复制这个文件，我们需要知道把它放在哪里。

根据安装 Ruby 的位置，目录会有所不同。

以默认安装的Ruby 2.1.5为例，放在C:\Ruby21

打开命令提示符并输入:

C:>gem which ruby​​gems C:/Ruby21/lib/ruby/2.1.0/rubygems.rb 现在，让我们找到那个目录。在同一窗口中，输入文件扩展名之前的路径部分，但使用反斜杠代替:

C:>启动 C:\Ruby21\lib\ruby\2.1.0\rubygems 这将在我们指定的目录中打开一个资源管理器窗口。

Step 3: Copy new trust certificate

现在，找到 ssl_certs 目录并复制我们从上一步中获得的 .pem 文件。

它将与其他文件一起列出，例如 GeoTrustGlobalCA.pem。

Step 4: Profit

实际上没有第 4 步。您现在应该可以毫无问题地安装 Ruby gems。
