每个C＃脚本都会在控制台上引发错误

Question

我刚刚用全新安装创建了一个Unity项目，还创建了C＃脚本并附加到3D游戏对象（多维数据集），但是当我双击打开脚本时，它会立即显示：

Exception thrown while invoking [OnOpenAssetAttribute] method 'Unity.CodeEditor.CodeEditor:OnOpenAsset (int,int,int)' : InvalidOperationException: Cannot start process because a file name has not been provided.
System.Diagnostics.Process.Start () (at <d465e2b2e5054d2787d6364114c43446>:0)
(wrapper remoting-invoke-with-check) System.Diagnostics.Process.Start()
UnityEditor.DefaultExternalCodeEditor.OpenProject (System.String path, System.Int32 line, System.Int32 column) (at C:/buildslave/unity/build/Editor/Mono/CodeEditor/DefaultExternalCodeEditor.cs:96)
Unity.CodeEditor.CodeEditor.OnOpenAsset (System.Int32 instanceID, System.Int32 line, System.Int32 column) (at C:/buildslave/unity/build/Editor/Mono/CodeEditor/CodeEditor.cs:56)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

和

InvalidOperationException: Cannot start process because a file name has not been provided.
System.Diagnostics.Process.Start () (at <d465e2b2e5054d2787d6364114c43446>:0)
(wrapper remoting-invoke-with-check) System.Diagnostics.Process.Start()
UnityEditor.DefaultExternalCodeEditor.OpenProject (System.String path, System.Int32 line, System.Int32 column) (at C:/buildslave/unity/build/Editor/Mono/CodeEditor/DefaultExternalCodeEditor.cs:96)
Unity.CodeEditor.CodeEditor.OpenFileAtLineColumn (System.String path, System.Int32 line, System.Int32 column) (at C:/buildslave/unity/build/Editor/Mono/CodeEditor/CodeEditor.cs:31)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

例如，如果我尝试Debug.Log在脚本中使用，它会说

'Debug' does not contain a definition for 'Log'

没用。

我已经尝试过重新打开unity，创建另一个项目，安装另一个版本（我现在使用的是最新的2019.2.0b1），并且这种情况总是会发生，我正在使用Visual Studio，并且在Unity控制台中提示错误。

Answer 1

解决方案是将Visual Studio设置为Unity的默认编辑器，如评论部分所述。
