Nuxt项目中unstorage驱动[ERR_PACKAGE_PATH_NOT_EXPORTED]错误求助

我们团队通过npx create-nuxt-app OUR_PROJECT创建Nuxt模板项目，其他成员运行均正常，但一位使用全新MacBook Air的成员遇到如下错误：

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath ‘./drivers/fs’ is not defined by “exports” in /Users/ONE_USER/OUR_PROJECT/node_modules/unstorage/package.json imported from /Users/ONE_USER/OUR_PROJECT/node_modules/@nuxt/content/dist/module.mjs

已尝试重新克隆项目、安装Xcode命令行工具，问题仍未解决。所有成员的node_modules/unstorage/package.json中exports配置一致：

...,"exports": {
    "./drivers/*": {
      "import": "./dist/drivers/*.mjs",
      "require": "./dist/drivers/*.cjs",
      "types": "./dist/drivers/*.d.ts"
    },
    ".": {
      "import": "./dist/index.mjs",
      "require": "./dist/index.cjs"
    },
    "./server": {
      "import": "./dist/server.mjs",
      "require": "./dist/server.cjs",
      "types": "./dist/server.d.ts"
    }
  },...

该成员的NPM调试日志如下：

原因分析 #

从日志可见，该成员使用的Node.js版本为v14.3.0，而unstorage中./drivers/*这类通配符导出语法，需要Node.js v14.13.0及以上版本才支持。旧版本Node无法识别该通配符规则，因此报错提示./drivers/fs未在exports中定义。

解决方法 #

1. 升级Node.js版本
   将Node.js升级至v14.13.0或更高版本（推荐使用LTS稳定版，如v16.x或v18.x）。可以通过版本管理工具nvm操作：

   # 安装LTS版本
   nvm install --lts
   # 切换到LTS版本
   nvm use --lts
   

   若未安装nvm，可通过官方渠道下载安装包手动升级。

2. 重新安装依赖
   升级Node后，删除项目目录下的node_modules文件夹和package-lock.json文件，再执行：

   npm install
