【中文标题】无法在 mac 上打开 h2.jar【英文标题】：Unable to open h2.jar on mac 【发布时间】：2013-03-13 21:49:44 【问题描述】：

我正在尝试为我的 java 应用程序构建一个 H2 数据库，我认为它正在工作，但我无法执行 .jar 文件来查看它是否工作......我正在做这个和我的朋友一起，他有一个 mac，对他来说很好用，我们有相同的 java 版本

我尝试过双击 .jar 并尝试使用命令行打开它

java -jar h2-1.3.170.jar 它向我展示了那个异常

【问题讨论】：

您能检查一下您的/etc/hosts 文件吗？您使用 *** 还是特殊的防火墙？您是否默认使用 IPv6 并禁用了 IPv4？没有，我刚查了一下，没有你说的。 【参考方案1】：

要临时修复它，请编辑主机文件并将您的主机名附加到127.0.0.1 环回地址：
