通过ruby2.0.0在Windows上安装iconv时出错 通过ruby2.0.0在Windows上安装iconv时出错


我正在尝试安装iconv，但是当我运行以下命令时：

gem install iconv 

我的结果：

请帮帮我!!!! THX。

Answer 1

今晚我遇到了这个问题（Windows 7，Ruby 1.9.3）。我案例中的解决方案如下：

1. 安装＆＃34;完整包，除了来源＆＃34;来自http://gnuwin32.sourceforge.net/packages/libiconv.htm

2. 运行gem install iconv -v '1.0.4' -- --with-iconv-dir=/path/to/GnuWin32

如果这不起作用，我也首先按照这里的说明进行操作：http://donpepeto.com/2014/09/20/fixing-c-libraries-on-your-rubyrails-install-on-windows/（从GnuWin32安装中复制/ bin，/ include和/ lib的内容）他们没有工作他们自己，但一旦我运行设置，我就能安装宝石，所以也许这有帮助。我也有一个关于丢失的.gitignore的错误，但我忽略了，再次运行gem install ...它有效。

我在Windows 10上遇到了同样的问题。感谢@Emma Burrows和@ZeWaren。以下为我工作，

1. 安装libiconv; http://gnuwin32.sourceforge.net/packages/libiconv.htm
2. 将文件从/include和/lib复制到/bin文件夹，对我来说C:\Program Files (x86)\GnuWin32\bin
3. 将PATH（环境变量）设置为C:\Program Files (x86)\GnuWin32\bin
4. Exceute（Tricky one）：gem install iconv -- --with-iconv-dir="C:\Program Files (x86)\GnuWin32\"并在gem安装过程中快速将文件从/bin转移到C:\RailsInstaller\Ruby2.2.0\lib\ruby\gems\2.2.0\gems\iconv-1.0.4\ext\iconv
