安装fog -无法从ASCII-8位转换为UTF-8

Question

我需要安装fog来使用SDK与openstack接口并创建一个插件。到目前为止，我在第一步就失败了。我正在寻找关于如何调试这些错误的任何建议，以及对安装是否还在那里的任何意见。

由于某种原因，我得到了上述错误。我能做些什么来解决这个问题吗？

Answer 1

您需要更新rdoc：

gem update rdoc

然后再试着安装fog :您不应该看到这些错误。或者，如果您不愿意重新安装fog，则只需重新生成rdoc文档：

gem rdoc --all --overwrite

Answer 2

你的宝石安装正确。如果希望在将来阻止该错误，可以通过运行以下命令排除文档：

gem install fog --no-ri

哦，看，它现在安装得更快了，耶！
