我无法在Heroku上部署我的应用程序，每次我试图将代码推送到Heroku时都会收到以下错误。
首先，我使用命令heroku create创建了我的Heroku应用程序。然后，我将所有修改后的文件添加并提交到git暂存区，最后，当我试图使用git推送到Heroku时，它在后构建部分失败了。
我用于推送代码的命令：git push heroku master
我得到的错误：

有人能指导我如何解决这个错误吗？
我猜你已经检查了以下问题，对吧？

您也可以尝试不在推送中包含node_modules文件夹。
也尝试通过heroku网络和github回购来推动它
根据错误日志，axios包未作为依赖项安装在package.json中。
您可能已经在设备上全局安装了Axios，因此它将在本地工作，但在Heroku部署过程中，它无法找到这种依赖关系。
因此，通过运行以下命令安装它：
npm install axios
然后再试一次。如果同样的问题仍然存在，请共享您的package.json文件。
