【中文标题】带有 vscode 和 C# 扩展的 Ubuntu 19.10 上的 Unity3D：出现错误并且自动完成功能不起作用【英文标题】：Unity3D on Ubuntu 19.10 with vscode and C# extension : get an error and the autocomplete doesn't working 【发布时间】：2020-07-14 19:55:39 【问题描述】：我是一名 Web 开发人员 (symfony
在 Ubuntu 19.10 上，我下载了 unity Hub v2.3.0 (https://unity3d.com/get-unity/download)
我从 unity hub 安装了 unity3D v2019.3.7f1（最新稳定版）和一些选项（Linux & WebGL & windows build support）
我创建了一个简单的 2D 游戏
一切都像魅力一样，我可以在 unity3D 控制台中打开我的项目并运行我的新游戏而不会出现任何错误
在 Unity 中，当我创建一个 c# 脚本时，可以通过我的（非常简单的）文本编辑器 gedit 打开该文件。现在我想安装跨操作系统的 IDE 可视化代码，谢谢，当我编辑我的统一脚本时，我会得到一些有用的扩展和自动完成代码。
所以，我通过apt install 安装了vscode（我遵循了这个官方指南：https://code.visualstudio.com/docs/setup/linux）
我的 vscode 版本是：
经过一些网络搜索，我知道我必须安装 .NET 框架（也许我错了？）
我的 dotnet 版本（来自终端：dotnet --version）是 3.1.201
接下来我配置了统一参数以更改默认文本编辑器：
外部脚本编辑器：代码 code指路径/usr/bin/code，vscode的可执行文件 外部脚本编辑器参数："$(ProjectPath)" -g "$(File)":$(Line):$(Column) 默认值，我什么都没改我从 unity 创建了一个简单的 c# 脚本，我打开文件并自动打开 vscode（是的！）。从 vscode 我添加了两个公共变量（bool 'a' 和 Rigidbody2D 'b'）
我保存了我的脚本并转到unity app，变量a和b在界面上可见：
所有作品！ 但是现在，我想要来自 vscode 的自动完成代码。所以，我安装了 vscode c# 扩展。但是当安装完成时，会出现这条消息：

Attempted to update project that is not loaded: /home/okli/UnityProjects/SampleGame/Assembly-CSharp.csproj
有些东西似乎不起作用......但是，我可以修改并保存我的 c# 脚本（例如添加一个新的公共 var，该变量是在统一界面中添加的），但是自动完成代码不起作用，当我输入 public Rigidbod 并按 ctrl + space 不会显示任何自动完成帮助。
我不熟悉 C#/vscode/microsoft 技术，如果我忘记了什么和/或在尝试（坏）解决方案之前做错了什么，我更喜欢在这里问
感谢您的帮助！
编辑：我刚刚在 unity3D 界面上通知了这个错误
我会搜索一下这个错误...
在 0xBFE1A8 回答后编辑：
我创建了一个新项目“扑通” 在 UnityEditor 中，我将 Visual Studio Code Editor 版本更改为 1.1.3，然后单击“更新 1.1.3”按钮错误并没有消失，所以我继续：
我在“Packages/manifest.json”中将“com.unity.ide.vscode”修改为1.1.3 在 UnityEditor 中，选中“生成所有 .csproj 文件”复选框 然后，我在“资产”菜单中单击“全部重新导入”毕竟，vsecode中的自动完成代码不起作用，但错误日志更小：

【问题讨论】：
【参考方案1】：所以我找到了一个适合我的修复程序。 Omnisharp 网站 (https://github.com/OmniSharp/omnisharp-vscode) 说过，在 linux 上，您需要将 Use Global Mono for Omnisharp 设置为“从不”。默认为“自动”
相反，我可以通过将使用全局单声道设置为“始终”来修复此错误，并且它似乎可以正常工作。我不再收到错误，并且智能感知正在工作。
另外，我已经安装了 mono 和 dotnet。
【讨论】：
【参考方案2】：如果 vscode unity auto complete 不起作用，请安装旧版本的 c# extensio，方法是单击配置按钮
【讨论】：
【参考方案3】：我有同样的问题，但与 MonoVersion 无关。降级到 1.1.3 和 生成 csproj 文件就可以了。我觉得很奇怪，因为这个错误与 1.1.4 版本有关，并开始进一步调查 vscode 扩展的 1.2.1。问题出在sln 文件中，我找到了一个简单的解决方案。
在 UnityEditor 中转到：[Edit]->[Preferences]->[External Tools]：点击复选框为以下各项生成 .csproj 文件：嵌入包，然后点击重新生成项目文件按钮来解决自动完成问题。
它在 sln 文件中添加了一些行，现在自动完成功能无需降级扩展即可工作。
希望对你有帮助！
【讨论】：
我检查了所有这些框是否正确，它解决了这个问题。但是您的回答为我指明了正确的方向，它甚至可能仅适用于检查“嵌入式软件包”。谢谢！【参考方案4】：此警告是已知的Visual Studio Code Editor 1.1.4 bug。 根据this information，导致错误的是 Omnisharp 扩展：
此问题是由扩展程序引起的，请与 存储库（或联系人）扩展已在 VS 的概述中链接 代码或 VS Code 的市场。另请参阅我们的问题报告 指导方针。
编码愉快！
对我来说，降级到软件包的 1.1.3 版本可以解决问题。
在 UnityEditor 中转到：[Window]->[Package manager]->[Visual Studio Code Editor]->：选择 1.1.3 版本并点击“更新 1.1. 3" 按钮。
如果错误在那之后没有消失：
1) 更改了 "com.unity.ide.vscode": "1.1.3" 在 "Packages/manifest.json" 2) 在 UnityEditor 中转到：[Edit]->[Preferences]->[External Tools]: 设置“生成所有 .csproj 文件" CheckBox 为真。 3) 在 UnityEditor 中转到：[Assets]->[Reimport All]有人说，如果你降级到 1.1.3 并在升级到 1.2.0 之后立即修复错误，但我没有尝试过。
