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

请按照下面的说明操作，这将解决您的问题。

步骤很简单：

第一步:获取新的信任证书

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位置(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。

第2步:在安装中找到RubyGems证书目录

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Ruby安装位置的不同，目录也会有所不同。

以Ruby 2.1.5的缺省安装为例，该安装位于C:\Ruby21

打开命令提示符，然后键入：

rubygems C:/ruby21/ C:>gem /ruby/2.1.0/rubygems.rb现在，让我们找到那个目录。在同一窗口中，输入直到文件扩展名的路径部分，但使用反斜杠：

ruby：\ruby21\lib\ C:>start \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。

第3步:复制新的信任证书

现在，找到ssl_certs目录并将我们从上一步获得的.pem文件复制到里面。

它将与GeoTrustGlobalCA.pem等其他文件一起列出。

第四步:利润

实际上没有第四步，你现在应该可以毫无问题地安装Ruby gem了。
