在Fedora上安裝Capybara-webkit

Question

所以我在Fedora 17上嘗試安裝Capybara Webkit。 我按照這里的指示進行操作，並為該項目的另一個（近乎相同）分支安裝了軟件包，因此我知道它可以工作。

當我嘗試bundle install ，出現此錯誤。 任何人都有想法，還是我應該與co一起記錄錯誤？

安裝capybara-webkit（0.12.1）時發生錯誤，並且Bundler無法繼續。 捆綁之前，請確保gem install capybara-webkit -v '0.12.1'成功。

Answer 1

版本0.12.1是gem的過時版本-我為以前的項目安裝了類似版本時遇到很多麻煩。

我建議升級到較新的版本-依賴項將更新，並且安裝將減少很多麻煩。

capybara-webkit依賴於Qt的WebKit實現，Qt是跨平台開發工具包。 您需要下載Qt庫以構建和安裝gem。 下載和安裝QT的說明： https : //github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit
