eclipse打开,提示Fail to create the java Virtual Machine 解决方法: 1.到eclipse安装目录下,找到eclipse.ini 2.按键盘ctrl+F,复制以下字符“launcher.XXMaxPermSize”,去掉引号,查找 3.将随后出现的两个216m改成128m

我安装的是Myeclipse 10.7.1.装上好久没用,今天启动突然报错:Failed to create the Java Virtual Machine. 检查Myeclipse安装好使用时好的啊,近期也没用,可能是近期升级了本地单独安装的jre版本导致的吧(Myeclipse使用自己的jre的). 整理了如下2个解决办法,可以选择一个使用,我选择的是第2个.经测试都ok. 方法一: 找到Myeclpise路径下的myeclipse.ini文件: 编辑将Xmx(JVM Heap最大允许的尺
