一、环境:Windows7

二、Unity2018.4、Unity2019

现象:打开Unity,新建一个空项目,在Console中输出几个Error,显示只有时间戳,没有内容

无法运行此空项目

三、查看Editor.log

发现有以下Log:

-----CompilerOutput:-stdout--exitcode: -2147450750--compilationhadfailure: True--outfile: Temp/Unity.TextMeshPro.dll
-----CompilerOutput:-stderr----------
Failed to load the dll from [?.], HRESULT: 0x80070057

The library hostfxr.dll was found, but loading it from C:\Program Files\Unity201918f1\Editor\Data\Tools\Roslyn\hostfxr.dll failed

  - Installing .NET Core prerequisites might help resolve this problem.

-----EndCompilerOutput---------------
- Finished compile Library/ScriptAssemblies/Unity.TextMeshPro.dll

表示.NET Core有问题,去微软下载KB2533623补丁即可:

下载装好就OK了

 

* 此问题仅存在Windows7中,Windows10无此问题
