启动测试时，尽管赛普拉斯中存在模块，但找不到模块“ fs-extra”错误

问题描述

刚刚遇到了这个问题。启动测试后，此错误会出现在cypress上下文窗口中。

@H_502_3@ Can't start server

The plugins file is missing or invalid.

Your pluginsFile is set to /Users/alexanderti/WebstormProjects/klickly-autotests-js/cypress/plugins/index.js,but either the file is missing,it contains a Syntax error,or threw an error when required. The pluginsFile must be a .js or .coffee file.

Please fix this,or set pluginsFile to false if a plugins file is not necessary for your project.

一切正常，直到我通过Webstorm的UI提示意外在package.json中安装了fs-exta模块，然后将其卸载了。还删除了./node_modules并重新安装。 但是错误仍然存​​在。

我已经通过npm ls fs-extra检查了模块的可用性，并且表明它存在

解决方法

只需将其添加到您的package.json中：

converters

为我解决了这个问题。我还添加了两个以避免更多问题：

"browser": {
    "fs": false
  }
,

已通过重新安装node_modules目录但已删除package-lock.json修复，这可能是因为它使用的是旧版本。现在已修复
