伊斯坦布尔封面抛出奇怪的错误

Question

尝试运行伊斯坦布尔封面，但得到以下一组错误，似乎无法修复它们。这是一个简单的代码覆盖率测试。实际的命令是：

istanbul cover --dir ../artifacts --report html -- ./node_modules/mocha/bin/_mocha tests/unit/* --recursive --reporter spec

我的错误如下：

如果应用程序是基于GUI的，并且如果您已经附加了display，应用程序仍然无法打开display，请尝试此...

您需要导出它的地址。通常是0.0，因此您的命令将类似于“导出DISPLAY=:0.0”，如果不起作用，请尝试将0.0更改为0，然后它可以找到显示。
