推荐答案

您的JAVA_HOME和PATH在您的etc配置文件中写入了两次，第二次用jre JAVA_HOME覆盖了它，因此javac将无法工作.在etc/profile的末尾取出第二个JAVA_HOME和PATH分配，然后重新启动

Your JAVA_HOME and PATH are being written twice in your etc profile, and the second time is overwriting it with the jre JAVA_HOME so javac will not work. Take out the second JAVA_HOME and PATH assignment at the end of your etc/profile and reboot
