取消在Heroku上部署MERN应用程序的费用未安装reactHelpers软件包

如何解决取消在Heroku上部署MERN应用程序的费用未安装reactHelpers软件包

这是我第一次与Heroku合作。我已按照有关如何在Heroku上部署应用程序的说明进行操作。但是我在部署时总是遇到错误。日志文件指出我需要安装ReactHelpers，但是我从来不需要安装此软件包。它还告诉我通过运行以下命令进行安装：npm install ../utils/reactHelpers。但是我无法在我的项目中运行此命令。

错误消息如下：

./node_modules/@material-ui/core/esm/Slider/Slider.js

Cannot find module: '../utils/reactHelpers'. Make sure this package is installed.

这是错误日志：

解决方法

这是您的df2.mean(axis=1).sort_values(ascending = False) 库实例所需的模块，无法找到。尝试删除您的df2.mean(axis=0).sort_values(ascending = False) 文件夹，然后再次运行@material-ui。这将重新安装依赖关系树，并有望解决您遇到的问题。
