can not install from sources on win10 with unreal engine 4.18

[husha1993]

Hi, I followed the instructions here to install from sources on win10 with unreal engine 4.18, https://github.com/20tab/UnrealEnginePython#installation-from-sources-on-windows-64-bit, the attached are the errors when building: 1>------ Build started: Project: UE4, Configuration: BuiltWithUnrealBuildTool Win32 ------ 2>------ Build started: Project: UrbanCity, Configuration: Development_Editor x64 ------ 2>C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\VC\VCTargets\Microsoft.Cpp.props(31,3): warning MSB4011: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\VC\VCTargets\Microsoft.Makefile.props" cannot be imported again.

I have tried to comment the 530 line in UnrealEnginePython.cpp. While it was successfully build, the .uproject can not be launched in unreal engine, the screen shot are attached:

Hi, you should clone the latest code as it contains a fix for 4.18

[husha1993]

Yes, I'm using the latest code and the above building error is from the latest code.

@husha1993 pull-again two dumb fixes were missing, sorry

Hi, The latest code is built successfully with the python path set as my anaconda environment in UnrealEnginePython.Build.cs. But the .uproject can not be launched in unreal engine, the error are the same as the screen shot attached above. I click 'debug the program', and the error is like this:

[husha1993]

I thought it was related to the environment variables, so I restart my computer to make sure the path variable takes effects. But the .uproject still can not be launched in unreal engine. I click 'debug the program', and the error is like this:

[husha1993]

Finally I make it... I should set the python path as the base conda python path. Any user specific conda path failed.

@husha1993 I think some people tumbled on similar issues. If you have time, it would be cool, if you could do a quick video tutorial. Especially people coming from linux would appreciate the steps on Windows.

Sorry about my late reply... I followed the instructions here: https://github.com/20tab/UnrealEnginePython#installation-from-sources-on-windows-64-bit

In order to use the anaconda python, I followed the instructions mentioned in the above link: "By default the build procedure will try to discover your python installation looking at hardcoded known paths. If you want to specify a custom python installation (or the autodetection simply fails) you can change it in the Source/UnrealEnginePython/UnrealEnginePython.Build.cs file at this line: https://github.com/20tab/UnrealEnginePython/blob/master/Source/UnrealEnginePython/UnrealEnginePython.Build.cs#L10"

I set the private string pythonHome = "C:/Program Files/Anaconda3";
