如下图所示，第一次打开项目的时候报错，
内容大致为：
FileNotFoundException: Could not find file “D:\GithubProjects\Navigation\VoxelWorldandAstarRoadGenerator\Voxel-World-and-A-star-Road-Generator\Voxel World and A-star Road Generator\Library\PackageCache\[email protected]\Tests\Editor\Unity.Analytics.StandardEvents\Unity.Analytics.StandardEvents.EditorTests.asmdef”.
System.IO.FileStream…ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/FileStream.cs:305)
System.IO.FileStream…ctor (System.String path, FileMode mode, FileAccess access, FileShare share)
(wrapper remoting-invoke-with-check) System.IO.FileStream:.ctor (string,System.IO.FileMode,System.IO.FileAccess,System.IO.FileShare)
System.IO.File.OpenRead (System.String path) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:363)
System.IO.StreamReader…ctor (System.String path, System.Text.Encoding encoding, Boolean detectEncodingFromByteOrderMarks, Int32 bufferSize) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/StreamReader.cs:167)
神奇的是，可以按Clear清除掉Console里的内容，就不会报错了，然而点击Play后会有新的报错，但是有没有提示具体问题出在哪里，如下图所示：
报错内容如下：
All compiler errors have to be fixed before you can enter playmode!
UnityEditor.SceneView:ShowCompileErrorNotification()
如果重新打开Unity，仍然会发现第一个图所示的报错，这就很神奇。
解决办法
根据错误提示FileNotFoundException: Could not find file，应该是文件路径太长了，导致Unity找不到，我的路径有这么长
D:\GithubProjects\Navigation\VoxelWorldandAstarRoadGenerator\Voxel-World-and-A-star-Road-Generator\Voxel World and A-star Road Generator
于是直接把项目移到D盘，发现可以正常运行了
