我正在使用支持es7的无服务器框架创建项目。但是当我尝试使用以下命令在本地运行我的函数时,我收到意外的令牌导出错误
serverless invoke local --f hello
我想我已经包含了所需的babel依赖项 -

我该怎么做才能摆脱这个错误?
答案 0 :(得分:0)
我看到了这个错误,并且它是非描述性的。我相信这意味着抛出的异常并未被捕获。当出现运行时语法错误时,它也会出现,例如使用未定义的变量。这是我的工作流程与您的工作流程不同,但允许我设置断点并逐步执行代码。由此我可以识别坏线。
安装无服务器脱机,以便您可以在本地运行项目。安装Visual Studio代码,以便有一个IDE可以调试。我已经将我的launch.json发布到Breakpoints not being hit when debugging Serverless in vscode设置一个断点然后用浏览器或卷曲点击你的enpoing。
