在Ubuntu10.04上的Rails 3.2.10中安装capybara-webkit 1.0.0时出现的问题

Question

问题

我无法让Capybara-webkit 1.0.0安装到我的Rails 3.2.10项目中。

当我运行bundle install时，我会得到以下错误。

同样，当我将capybara-webkit转回0.12.1版本(2012年5月30日)时，它会安装得很好。

注意:我在OSX10.8和Ubuntu10.04上都有同样的问题。

错误

An error occurred while installing capybara-webkit (1.0.0) with bundler

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

思考

• 它似乎与QT有关，尽管我已经安装了建议的4.8.5

我的配置

• Ubuntu 10.04
• Postgres 9.2
• QT4.8.5用于水豚支持
• Redis版本1.2.0
• Rbenv 0.4.0-54
• Ruby 1.9.3-p 392
• 创业板1.8.23
• 邦德勒1.3.5
• Rails 3.2.10
• 水豚-webkit 1.0.0

Answer 1

那可是很多宝石啊。首先要尝试的是确保您拥有Capybara的必要版本(大于2.0.2)：

gem 'capybara', '>= 2.0.2'

如果这没有帮助，试着注释掉你所包含的宝石块，直到宝石文件生成。一旦完成，您可以尝试取消对不同宝石的注释，直到它再次失败为止。然后，你至少会知道冲突在哪里，这样你就可以尝试解决它。有关capybara-webkit依赖项的更多信息，在这里：http://rubygems.org/gems/capybara-webkit

您需要安装编译gem所需的库：

# ubuntu    
sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui
