The error is misleading here. The problem is likely to be that you dont have permissions in directory /usr/lib/jython-25/cachedir/packages and possibly the parent directory cachedir too. If you look at the first line of the output when wsadmin.sh starts, it actually implies this.
这里的错误具有误导性。问题很可能是您在目录 /usr/lib/jython-25/cachedir/packages 中没有权限，也可能在父目录 cachedir 中没有权限。如果您查看 wsadmin.sh 启动时输出的第一行，它实际上暗示了这一点。
