我在 Linux AWS 上运行 Ruby 2.0.0p645。
我尝试运行 gem install mechanize，但出现此错误:
Building native extensions. This could take a while...
ERROR: Error installing mechanize:

我该如何解决这个问题，以便我可以在我的虚拟盒子上安装 mechanize？
最佳答案
看起来您可能需要安装 libstdc++。对于 Debian 或 Ubuntu，请尝试:
sudo apt-get install build-essential libstdc++6
然后重试安装 gem。
