在 Debian 10 GNU/Linux 中运行 Unity 的 TextMesh Pro 错误

Question

I started to try Unity GNU/Linux version. I got a project in my job that was written in Unity Editor version 5.6.6f2 for Windows. I could open the project in Unity Editor version 2019.3.8f1 after Unit Hub converting it for this newer version.

I'm getting a series of building errors now. And many of them are related to TextMesh Pro Asset in scripts generated during the building. Like

Library/PackageCache/com.unity.textmeshpro@2.0.1/Scripts/Runtime/TMP_FontAsset.cs(405,34): error CS0029: Cannot implicitly convert type 'UnityEngine.TextCore.FaceInfo' to 'TMPro.FaceInfo'

There's a log file, Logs/Packages-Update.log , that I suppose is related to the updates made when converting the project from 5.6.6f2 version to 2019.3.8f1 version. The content of that file is

I'm totally new to Unity and I don't use Windows. So I'm wondering if that have something related to C# scripting (like libraries that I have to install in Debian to properly compile a project), or if the errors are specific to TextMesh Pro asset etc.

If anyone have had this type of error or can give me tips to make Unity works in a Debian GNU/Linux environment...

Answer 1

1. Delete the old version of TextMesh Pro in the Asset folder

2. Reopen Project

3. Window -> TextMeshPro -> Import TMP essentials

4. Window -> TextMeshPro -> Project Files GUID Remapping Tool.

5. Scan & Save.

This will update the project and fix all missing TMP scripts.
