VS Code中Prettier保存不格式化：无效配置文件求助

问题重现 #

在Xubuntu虚拟机的VS Code中进行Odin Project练习时，保存代码触发Prettier格式化出现以下错误：

["INFO" - 5:58:23 AM] Formatting completed in 6ms.
["INFO" - 5:58:30 AM] Formatting file:///home/t/repos/css-exercises/flex/03-flex-header-2/style.css

当前VS Code settings.json配置：

{
  "workbench.colorTheme": "Default Dark+",
  "editor.guides.bracketPairs": true,
  "workbench.iconTheme": "vscode-icons",
  "editor.linkedEditing": true,
  "security.workspace.trust.untrustedFiles": "open",
  "prettier.configPath": "/home/t/repos/eslintrc.prettierrc",

  "[javascript]": {
    "editor.formatOnSave": true,
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
  "[typescript]": {
    "editor.formatOnSave": true,
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
  "[css]": {
    "editor.formatOnSave": true,
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  },

  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "gitlens.hovers.currentLine.over": "line",
  "liveServer.settings.donotShowInfoMsg": true,
  "liveServer.settings.AdvanceCustomBrowserCmdLine": "/opt/firefox/firefox",
  "editor.formatOnSave": true,
  "prettier.useEditorConfig": false
}

已尝试：切换格式化器、卸载重装Prettier扩展、调整useEditorConfig等设置、移动配置文件位置，均无效。

修复步骤 #

1. 修正Prettier配置文件命名与格式 #

Prettier无法识别无后缀的.prettierrc文件，需给配置文件添加明确后缀：

• 将/home/t/repos/eslintrc.prettierrc重命名为.prettierrc.json（JSON格式）、.prettierrc.js（JS格式）或.prettierrc.yml（YAML格式）
• 更新settings.json中的prettier.configPath为新的文件路径，例如：

  "prettier.configPath": "/home/t/repos/.prettierrc.json"
  

• 确保文件内容符合对应格式要求（JSON需严格语法，JS需导出配置对象）

2. 确保项目本地安装Prettier依赖 #

在/home/t/repos目录下执行命令，安装本地Prettier：

npm install prettier --save-dev

若全局安装了Prettier，可通过which prettier获取安装路径，在VS Code设置中指定：

"prettier.prettierPath": "/usr/local/bin/prettier"

3. 清理缓存并重启VS Code #

• 关闭VS Code
• 删除项目目录下的.prettier-cache文件（如果存在）
• 删除VS Code缓存目录：

  rm -rf ~/.config/Code/Cache ~/.config/Code/CachedData
  

• 重新启动VS Code并测试格式化功能

4. 检查ESLint与Prettier集成配置 #

确保ESLint配置文件（如.eslintrc.json）正确集成Prettier：

• 已安装eslint-config-prettier和eslint-plugin-prettier依赖：

  npm install eslint-config-prettier eslint-plugin-prettier --save-dev
  

• ESLint配置中包含：

  {
    "extends": ["plugin:prettier/recommended"],
    "plugins": ["prettier"]
  }
