同下面的报错

[tsjslgy]

国内用户，直接度盘下载的，保证完整性一致，开始打开没有选项卡，来找原因结果已经有人提了，注释了问题的几行后选卡出现。正要高兴的时候，第二个错来了，同楼下的几位。于是乎仔细核对了文件名，又跑到hg 上核对了一次，开了魔法和不开魔法都尝试过，结果还是一样。

I had the same "NoneType" error message few times. I did not analyzed the code, but looks like checking and unchecking "Use FC" checkbox few times and re-running generation solved it for me. Try uncheck "Use FC" and run generation, then check "Use FC" again and run generation.
I can assume that there is no default value assigned to some object somewhere in the code.
