vscodeとC＃拡張を含むUbuntu 19.10上のUnity3D：エラーが発生し、オートコンプリートが機能しない
私はWeb開発者です（symfony <3;）C＃とMicrosoftテクノロジーは私にとって新しいものです！ ）そしてcovidの封じ込め中に、ゲームエンジンの単一性を備えたシンプルなゲームを作成したい
Ubuntu 19.10で、unity Hub v2.3.0をダウンロードしました（- https://unity3d.com/get-unity/download ）
Unityハブから、unity3D v2019.3.7f1（最新の安定版）をいくつかのオプション（Linux＆WebGL）でインストールしました＆Windowsビルドサポート）
シンプルな2Dゲームを作成しました
すべてが魅力のように機能し、プロジェクトを開いて、Unity3Dコンソールでエラーなしに新しいゲームを実行できます
Unityからc＃スクリプトを作成すると、（非常にシンプルな）テキストエディターgeditでファイルを開くことができます。ここで、クロスOSをインストールしたいと思いますIDE visualcodeおかげで、Unityスクリプトを編集すると、便利な拡張機能とオートコンプリートコードが得られます。
それで、apt installを介してvscodeをインストールしました（この公式ガイドに従いました： https://code.visualstudio.com/docs/setup/linux ）
Vscodeの私のバージョンは：
いくつかのWeb検索の後、.NETフレームワークをインストールする必要があることを理解しました（たぶん私は間違っていますか？）
私のdotnetバージョン（ターミナルから：dotnet --version）は3.1.201です
次に、デフォルトのテキストエディターを変更するためのunityパラメーターを構成しました。
- 外部スクリプトエディター：コード
- コードはパス/ usr/bin/code、vscodeの実行可能ファイルを参照します
- 外部スクリプトエディタの引数： "$（ProjectPath）" -g "$（File）"：$（Line）：$（Column）
- デフォルトの値、私は何も変更しませんでした
Unityから単純なc＃スクリプトを作成し、ファイルを開き、vscodeを自動的に開きました（そうです！）。 vscodeから2つのパブリック変数を追加しました（ブール 'a'とRigidbody2D 'b'）
スクリプトを保存してUnityアプリに移動すると、変数aおよびbがインターフェイスに表示されます。
すべての作品！しかし、今は、vscodeのオートコンプリートコードが必要です。それで、vscode c＃拡張機能をインストールしました。しかし、インストールが完了すると、次のメッセージが表示されます。
ログ全体は次のとおりです。

何かが機能しないようです...しかし、c＃スクリプトを変更して保存できます（例として新しいパブリック変数を追加し、変数はユニティインターフェイスに追加されます）が、public Rigidbodを入力するとオートコンプリートコードが機能しませんctrl + spaceを押してください。オートコンプリートのヘルプは表示されません。
C＃/ vscode/Microsoftテクノロジーに慣れていないので、（悪い）ソリューションを試す前に、何かを忘れたり、何か間違ったことをしたりするか、ここで質問することをお勧めします
助けてくれてありがとう！
編集：私はこのエラーをunity3Dインターフェイスで通知しました
このエラーについていくつか検索します...
0xBFE1A8回答後の編集：
- 新しいプロジェクト「プロップ」を作成しました
- UnityEditorで、Visual Studio Code Editorのバージョンを1.1.3に変更し、[Update 1.1.3]ボタンをクリックします
エラーが消えないので、私は続けました：
- 「Packages/manifest.json」で「com.unity.ide.vscode」を1.1.3に変更しました
- UnityEditorで、[Generate all .csproj files]チェックボックスがオンになっている
- 次に、[Assets]メニューの[Reimport All]をクリックします
これらすべての後、vsecodeのオートコンプリートコードは機能しませんが、エラーログは小さくなります。

私は同じ問題を抱えていましたが、MonoVersionとは関係がありませんでした。 1.1.3およびへのダウングレードcsprojファイルの生成で問題が解決しました。このエラーは1.1.4バージョンに関連しているため、私は奇妙なことに気付き、さらに1.2の調査を開始しました。 vscode拡張の1。問題はslnファイルにあり、簡単な解決策を見つけました。
UnityEditorに移動します：[Edit]-> [Preferences]-> [External Tools]：チェックボックスをクリックしてGenerate .csproj files for：Embedded packages、次にRegenerate project filesbutton toオートコンプリートの問題を解決します。
Slnファイルにいくつかの行が追加され、オートコンプリートは拡張機能をダウングレードする必要なく機能するようになりました。
それが役に立てば幸い！
