Question

每当我到达需要运行此命令type <file_name> | heroku pg:psql 或 type db.js | heroku pg:psql HEROKU_POSTGRESQL_CYAN的步骤时，我都尝试将具有Postgres数据库的节点应用程序部署到Heroku。具体来说，我收到此错误：syntax error at or near *。 db.js是我的迁移文件，在运行命令之前，我先进入包含该文件的构建文件夹。我在服务器文件夹中编写了es6代码，然后将其编译为es5到了一个构建文件夹中。在下面找到我遇到的错误。

运行后出现错误消息：

type db.js | heroku pg:psql HEROKU_POSTGRESQL_CYAN

尽管我的应用是通过应用的Heroku URL发布的，但api的Postgres表行还是空的。

{
rows: [ ],
rowCount: 0
}

当我运行“键入<file_name> | heroku pg：psql”时，为什么会出现错误提示“ *或附近的语法错误”
