我在亚马逊 ec2 上安装了 icu

sudo apt-get install libicu-dev

然后我安装了 charlock_holmes：

gem install charlock_holmes

在我看来，它已成功安装：

Building native extensions. This could take a while...
Successfully installed charlock_holmes-0.6.9.4
1 gem installed

之后我得到了这个：

.../shared/bundle/ruby/1.9.1/gems/charlock_holmes-0.6.9.4/lib/charlock_holmes.rb:1:in `require':
.../shared/bundle/ruby/1.9.1/gems/charlock_holmes-0.6.9.4/lib/charlock_holmes/charlock_holmes.so: 
  undefined symbol: _ZN6icu_518ByteSink15GetAppendBufferEiiPciPi   
.../shared/bundle/ruby/1.9.1/gems/charlock_holmes-0.6.9.4/lib/charlock_holmes/charlock_holmes.so (LoadError)

我也尝试使用此命令进行安装：

gem install charlock_holmes -- --with-icu-dir=/usr/local/lib/

错误仍然出现。在我看来，我需要以某种方式指定正确的目录--with-icu-dir

我指定的原因/usr/local/lib是因为 icu 库安装到该目录中。

gem install charlock_holmes -- --with-icu-dir=/usr/local

当我遇到这个问题时为我工作。依赖项足够聪明，可以在 lib 中查找 lib，在头文件中查找 include，以及在 /usr/local 下的其他适当位置。

我在安装 gem 时遇到了这些讨厌的测试错误：

但它们在运行时似乎并没有影响我的应用程序。
