Exception in thread "main"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "main"
这是setenv.sh中的JAVA_OPTS变量

export JAVA_OPTS=“-Xms1g-Xmx2g-XX:MaxPermSize=2g”

如果我从intellij运行tomcat（使用相同的选项），它工作正常，并且部署了web war。运行

catalina.sh jpda start from命令行给出了该错误

使用JRE_HOME:/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/HOME

` 我最近使用了jdk1.8，然后使用此链接中的答案将其删除

非常感谢您的帮助。

JAVA\u OPTS
在外部启动时未设置（不是通过IDE）

尝试设置
JAVA\u选项

export JAVA_OPTS="-Xms1g -Xmx2g -XX:MaxPermSize=2g"
在从命令行启动服务器之前，如果服务器正常工作，则在
~/.中添加此导出语句。当您从外部启动服务器时（不是通过IDE），bash_profile
JAVA_OPTS
）

尝试设置
JAVA\u选项

export JAVA_OPTS="-Xms1g -Xmx2g -XX:MaxPermSize=2g"
在从命令行启动服务器之前，如果服务器正常工作，则在
~/.bash\u profile

中添加此导出语句。从终端尝试
echo$JAVA\u OPTS
它不会返回任何内容。从终端尝试
