Question

尝试将数据库表迁移到heroku，并遇到以下错误。当我运行

heroku pg:credentials:url

我可以获取连接URL。但是当我尝试运行脚本

"env SSL=true DATABASE_URL=postgres://azgtqialharhur:647e8109bcabdeda90c00f6ca961e603f01529177d2ddefb4f1cf9bf47552653@ec2-54-243-44-102.compute-1.amazonaws.com:5432/df6c2t2q7bb1s4 npm run migrate"

我遇到以下错误：

> env SSL=true DATABASE_URL=postgres://azgtqialharhur:647e8109bcabdeda90c00f6ca961e603f01529177d2ddefb4f1cf9bf47552653@ec2-54-243-44-102.compute-1.amazonaws.com:5432/df6c2t2q7bb1s4 npm run migrate

我在各种项目中都看到了这个错误。我已经看到通过安装早期版本的postgrator-cli软件包可以解决此问题。

我看到的另一种解决方案是使用yarn而不是npm。
