在Heroku上部署节点应用程序时出错

Question

我使用git push heroku命令将节点应用程序推送到heroku，但显示以下错误。

remote: Compressing source files... done.

我不知道我在做什么错。 如果有人可以纠正我，那将不胜感激。

这是我的package.json文件。

我目前在我的项目中使用Vue.js以及数据库为Mongodb的Node.js和sockets.io。

Answer 1

读完您提供的错误后，它提到它在构建过程中，它在line 17 of package.json上期望有另一个键值对。

我通过JSON运行了package.json ，发现了一些问题，如下所示-

第11行的解析错误 ： 您应该删除第11行和第12行之间的换行符。
"unit": "cross-env BABEL_ENV=test karma start test / unit / karma.conf.js--single - run ",

分析第14行的错误 ：： 您应该删除第14和15行之间的换行符。
"lint": "eslint --ext .js,.vue src test/unit/specstest / e2e / specs ",

解析第15行的错误 ：： 您应该删除逗号，因为这是脚本的最后一个属性。
"start": "node server.js"

第15行上的重复键“开始” ：：*您需要确定是否要使用开始脚本
"start": "node build/dev-server.js", 或 "start": "node build/dev-server.js",

修复这些问题应该可以解决您的构建错误。

Answer 2

检查一下，您有错误。 Json错误语法错误

“单位”：同一行中的所有测试均与“棉绒”相同

并删除两个开始，还删除了第17行中的逗号

新文件
