Question

我收到以下错误：

% gem install wkpdf
ERROR:  Could not find a valid gem 'wkpdf' (>= 0) in any repository
ERROR:  Possible alternatives: wkpdf

我怀疑它与wkpdf需要universal-darwin有关，而系统有universal-darwin-14：

% gem list -r | grep wkpdf
plessl-wkpdf (0.3.5 universal-darwin)
wkpdf (0.6.11 universal-darwin)
% gem env

根据wkpdf的作者，Yosemite不支持wkpdf所依赖的RubyCocoa，并且他不太可能在不久的将来重新实现wkpdf。

我转而使用wkhtmltopdf代替;见http://wkhtmltopdf.org/。

osx-yosemite上的“gem install wkpdf”失败
