无法在 Rails 4 中使用 bundle install 命令安装 capybara-webkit

Question

我在 Rails 4 应用程序中执行命令 bundle install 时出现以下错误。

> ruby -v
ruby 2.1.8p440 (2015-12-16 revision 53160) [i386-mingw32]

> rails --version
Could not find gem 'capybara-webkit x86-mingw32' in any of the gem sources listed in your Gemfile or available on this machine.
Run `bundle install` to install missing gems.

我的 Gemfile

...
.....
group :development, :localtesting, :test do
  gem 'sqlite3',     '1.3.11'
  gem 'byebug',      '3.4.0'

'qmake' is not recognized as an internal or external command,
operable program or batch file.

Answer 1

安装说明位于 capybara-webkit wiki - https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit。您需要安装 Qt 5.5.1（仅当您单独构建 QtWebKit 模块时才支持 5.6）

Answer 2

我有 OS X El Capitan 系统。我跟踪了这个 link :

https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit

然后

gem install capybara-webkit -- --with-opt-include=/usr/local/bin/qmake

这个问题已经解决了。

Answer 3

Ubuntu

sudo apt-get update
sudo apt-get install qt5-default libqt5webkit5-dev gstreamer1.0-plugins-base gstreamer1.0-tools gstreamer1.0-x

Answer 4

'qmake' is not recognized 可能意味着没有安装 Qt

brew update
cd $( brew --prefix )/Homebrew/Library/Taps/homebrew/homebrew-core
git checkout 9ba3d6ef8891e5c15dbdc9333f857b13711d4e97 Formula/qt@5.5.rb
brew install qt@5.5
echo 'export PATH="$(brew --prefix qt@5.5)/bin:$PATH"' >> ~/.bashrc

完整的安装过程是here

Answer 5

我不得不运行:

QMAKE="$(brew --prefix qt@5.5)/bin/qmake" gem install capybara-webkit

为了在出现错误后安装 gem：qt@5.5: unknown version :mountain_lion 并遵循 Homebrew instructions:

中的注释步骤

注意：如果出现错误：qt@5.5：未知版本：mountain_lion，注释行 #25 in Formula/qt@5.5.rb

Answer 6

对于AltLinux，应该执行以下操作：

从 root 安装开始 gem-capybara-webkit-devel 包：
```
# apt-get install gem-capybara-webkit-devel
```
导出编译所需的 PATH 附加项：
```
$ export PATH=/usr/share/qt5/bin:$PATH
```
使用捆绑器安装 gem
```
$ bundle
```
