如何修复“无头异常”并设置X11显示变量以运行fastqc？

Question

我对此很陌生，尝试运行FastQC时，我不断收到错误消息。我有Mac OSx的最新JDK更新，我想我已经安装了FastQC。

这是错误消息：

[cdeiter@tlog1 pathcda]$ fastqc #fox_dog_RNAseq.2018816
Exception in thread "main" java.awt.HeadlessException: 
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
