Error:The JVM could not be started. The maximum heap size (-Xmx) might be too large or an antivirus or firewall tool could block the execution.修改安裝目錄下的文件PhpStorm 6.0\bin\PhpStorm.exe.vmoptions-Xms128m-Xmx512m-XX:MaxPermSize=250m-XX:ReservedCodeCacheSize=64m-XX:+UseCodeCacheFlushing-ea-Dsun.io.useCanonCaches=false比如改成了256m.
