在 uni-app 开发过程中,遇到运行终端后白屏或点击预览也是白屏的情况,可能是由多种原因引起的。以下是一些常见的排查步骤和解决方法:


1. 检查项目依赖

确保项目依赖安装完整,运行以下命令重新安装依赖:

npm install

或者使用 yarn

yarn install

2. 检查编译日志

运行项目时,观察终端是否有报错信息。如果有错误日志,根据提示解决问题。


3. 检查路由配置

确保 pages.json 中的路由配置正确,尤其是首页路径是否正确。例如:

{
  "pages": [
    {
      "path": "pages/index/index",
      "style": {
        "navigationBarTitleText": "首页"
      }
    }
  ]
}

4. 检查页面文件

确保首页文件存在且路径正确。例如,如果首页是 pages/index/index.vue,检查该文件是否存在且内容正确。


5. 清除缓存

有时候缓存可能导致问题,尝试清除缓存并重新运行项目:

npm run dev:clean

或者手动删除 unpackagenode_modules 文件夹,然后重新安装依赖。


6. 检查网络请求

如果页面依赖网络请求,检查请求是否正确,是否有跨域问题。


7. 检查开发者工具配置

如果是运行在微信开发者工具中,检查是否开启了 ES6 转 ES5增强编译。可以在微信开发者工具的 详情 -> 本地设置 中勾选相关选项。


8. 检查 uni-app 版本

确保 uni-app 版本是最新的,运行以下命令更新:

npm update [@dcloudio](/user/dcloudio)/uni-app
