最佳答案
我在运行 ant build 时也遇到了同样的问题。
因为我不知道这个术语“启动现代编译器时出错”，所以我运行带有 verbos 日志选项的命令，即 ant -v build 并最终在之前得到“内存不足错误”应用请增加JRE内存。
因此请应用set ANT_OPTS=-Xms256m -Xmx256m，然后运行ant build。问题将得到解决。

我正在用Ruby编写一个简单的程序来检查域列表是否被占用。基本上它循环遍历列表，并使用以下函数进行检查。require'rubygems'require'whois'defcheck_domain(domain)c=Whois::Client.newc.query("google.com").available?end程序不断出错(即使我在google.com中进行硬编码)，并打印以下消息。鉴于该程序非常简单，我已经没有什么想法了-有什么建议吗？/Library/Ruby/Gems/1.8/gems/whois-2.0.2/lib/whois/server/adapters/base.
