我正在尝试运行SQuirreL SQL。

我已下载并安装它，但是当我尝试运行它时，我收到以下错误消息：

I'm trying to run SQuirreL SQL.
I've downloaded it and installed it, but when I try to run it I get this error message:

Java虚拟机启动器。

无法找到主类。

程序将退出。

Java Virtual Machine Launcher.
Could not find the main class.
Program will exit.

我得到了这个的要点，但我不知道如何解决它。有帮助吗？

推荐答案

您的计算机上是否安装了Java？是否正确设置了bin目录的路径（换句话说，如果从命令行输入'java'，你会得到一个指令列表，或者你得到的结果是java不被认为是...... ）？

Is Java installed on your computer? Is the path to its bin directory set properly (in other words if you type 'java' from the command line do you get back a list of instructions or do you get something like "java is not recognized as a .....")?

您可以尝试从命令行（来自squirrel sql目录）运行 squirrel-sql.jar ），使用：

You could try try running squirrel-sql.jar from the command line (from the squirrel sql directory), using:

java -jar squirrel-sql.jar
