VS Code安装emojisense插件报错：End of file expected .jsonc [Ln 1, Col 23]

错误原因 #

你将VS Code原生配置项"javascript.validate.enable": false错误嵌套在了emojisense.languages对象内部，破坏了JSON的结构完整性，这直接导致了End of file expected .jsonc语法报错。

修正后的配置代码 #

将"javascript.validate.enable": false移到emojisense.languages对象外部，确保每个配置项层级正确：

"emojisense.languages": {
    "plaintext": {
        "markupCompletionsEnabled": true,
        "emojiDecoratorsEnabled": true
    },
    "abap": true,

},
"javascript.validate.enable": false

确保":"触发emoji补全 #

1. 确认目标语言的markupCompletionsEnabled已开启（比如你配置的plaintext已经开启）
2. 检查VS Code基础补全设置，确保字符串场景下补全触发：

"editor.quickSuggestions": {
    "other": true,
    "comments": false,
    "strings": true
}

保存配置后重启VS Code，输入":"即可触发emoji建议补全。
