Debug info has been saved to /tmp/qiime2-q2cli-err-cpq2ii3g.log【出现问题的原因】 问题在于，您使用的是一个交互式后端，它试图为您创建图形窗口，但由于您断开了启动模拟时可用的x服务器，所以失败了。
【解决方法】
使用非交互式后端(请参见后端？)比如：Agg(用于Png格式，PDF, SVG或PS。在生成图形的脚本中，只需在import matplotlib.pyplot as plt之前调用matplotlib.use(）即可，具体如下：
将导入更改为
import matplotlib
matplotlib.use('AGG')#或者PDF, SVG或PS
import matplotlib.pyplot as plt永久解决办法：
mkdir -p $HOME/.config/matplotlib/
echo"backend: Agg" >> $HOME/.config/matplotlib/matplotlibrc到此，关于“qiime2报错couldn't connect to display "localhost:12.0"怎么解决”的学习就结束了，希望能够解决大家的疑惑。理论与实践的搭配能更好的帮助大家学习，快去试试吧！若想继续学习更多相关知识，请继续关注亿速云网站，小编会继续努力为大家带来更多实用的文章！
