Ubuntu16下基于Unreal Engine 35%不动问题

首先确保我们装上了上述的两个软件包，之后到<UnrealEngine>文件夹下面双击运行下面这个文件<UnrealEngine/Engine/Binaries/Linux/UE4Editor>加载之后如下图所示。然后选择我们需要创建工程的文件放在哪里

如果打开UE失败，可以执行./UE4Editor -opengl3

35%的时候会卡住，也不报错误，这个很麻烦，程序员最害怕的就是明明没有达到预期效果，却没有报错，这简直是是灵魂的撕扯，明明应该是有问题的，你却只是卡住，没有报错

等待中，

官网解释https://answers.unrealengine.com/questions/449847/ue-412-stops-initializing-at-35.html

This is currently a known issue, UE-31175. This issue is being investigated by our developers; however, there is currently no timeline for when a fix will be released.

As an update, UE-31175 was marked as a duplicate of UE-24658. So here is the link to the correct issue on the public bug tracker: https://issues.unrealengine.com/issue/UE-24658

好像只是因为慢，好尴尬，就像是刘姥姥进大观园一样，给跪了，you should be patient

45%的时候又卡了，

找了官网，有个回答可以看看：

I have just installed the new 4.20.1 version on a 2012 macbook pro.

It took 45 mins to initialize for the first time. It froze at 35% for about 35mins.. Allowing Ue4 to bypass the firewall got it started again, sat at 45% for another 10mins then the rest was speedy.

The first time just takes a while.

差不多35%的时候半个多小时，我之前都是等不及就ctrl+c取消掉了，45%得再等10分钟，这次我就等着吧。反正是虚拟机，这次启动之后就不关闭了。反正内存也调成8G了，应该全部够用了。

top一下看CPU和内存使用率

用了不到4G，还可以。

有点烦，居然还有问题

好在有错误提示，可以找官网，

Hey! I ran into the same issue, but I found a way to fix it. I think this issue is caused by accidentally using "sudo" during the setup of your install. If you're like me, you made that mistake on reflex, then nuked the UnrealEngine folder and started again when nothing worked.

Unfortunately, the .config/Epic is first generated during setup (./GenerateProjectFiles.sh I think), so even though you nuked everything you're still going to run into problems down the road.

My "fix" was to remove the Epic folder from the .config folder (~/.config$ sudo rm -r Epic/).

最后的办法就是删除Epic/文件夹，终于打开了
