语言扩展项目似乎未加载语法（未提供语法消息）

Question

我正在尝试为Visual Studio代码创建一个简单的语言扩展。我使用“ yo代码”来生成语言支持扩展。添加我的语言名称，ID，扩展名等后，即使在扩展调试主机中运行tm范围检查器时，我仍然收到此消息“没有为<源。弧提供语法” ，即使vscode识别了语言。

不知道我现在可以尝试什么，因为该示例应该立即起作用

archsim.tmLanguage.json：

{
    "name": "ArchsimC",
    "scopeName": "source.arc",
    "patterns": [
        {
            "include": "#keywords"
        },
        {
            "include": "#strings"
        }
    ],
    "repository": {
        "keywords": {
            "patterns": [
                {
                    "name": "keyword.control.archsimc",
                    "match": "\\b(if|while|for|return)\\b"                  
                },
            ]
        },
        "strings": {
            "name": "string.quoted.double.archsimc",
            "begin": "\"",
            "end": "\"",
            "patterns": [
                {
                    "name": "constant.character.escape.archsimc",
                    "match": "\\\\."
                }
            ]
        }
    }
}

package.json：

{
    "name": "languagetest",
    "displayName": "LanguageTest",
    "description": "language server test",
    "version": "0.0.1",
    "engines": {
        "vscode": "^1.29.0"
    },
    "categories": [
        "Programming Languages"
    ],
    "contributes": {
        "languages": [
            {
                "id": "archsimc",
                "aliases": [
                    "ArchsimC",
                    "archsimc"
                ],
                "extensions": [
                    ".arc"
                ],
                "configuration": "./language-configuration.json"
            }
        ],
        "grammars": [
            {
                "language": "archsimc",
                "scopeName": "source.arc",
                "path": "./syntaxes/archsimc.tmLanguage.json"
            }
        ]
    }
}

test.arc

if(something)
{
    return;
}

根据我在vscode文档中看到的内容，通过在“ if”上运行inspect TM范围来指向tmLanguage文件。

有什么想法在这里，如果我做错了什么？
