当前工作目录不是基于 Cordova 的项目

Question

当运行ning ionic cordova 运行 browser --verbose 在我的 Ionic4 项目的根目录中时，我收到错误 "Current working directory is not a Cordova-based project."。请参阅下面的错误输出。

我注意到该命令创建了一个 "www" 文件夹，但几秒钟后又将其删除。当我在删除文件夹后手动添加文件夹时（但命令仍然是运行ning）我可以防止错误。但是 "www" 文件夹将保持为空，并且提供的网页将显示未找到文件。

Answer 1

尝试做一个 npm install。也许您的项目中缺少某些 Cordova 节点模块。

Answer 2

您是否尝试在运行命令之前创建 www 文件夹？

如果可行，请尝试将 www 文件夹添加到您的源代码管理系统（git、svn 等...），这样当您签出代码时，您就会创建该文件夹，从而防止构建系统尝试重新创建。

在您的 .gitignore 文件中（如果使用 git），添加以下行：

 # excludes everything inside the folder
www/*
# but do not exclude .gitkeep file, so the folder can be checked into the repository
!www/.gitkeep
