我无法运行Heroku应用程序。我想将一些数据导入我的heroku数据库。我这样做是通过运行：
heroku pg:psql
\copy tablename FROM 'db/tableInfo.csv' DELIMITER ',' CSV;
然后当我跑：
select* from tablename
根据需要打印出我从CSV上传的所有数据。 但是，当我转到我的应用程序并运行“heroku open”时，我的浏览器会显示一个页面，上面写着“我们很抱歉，但出了问题。”然后当我检查heroku日志时，它说“PG :: UndefinedTable：ERROR：relation”tablename“不存在” 我很困惑，因为当我去heroku网站时它说有3行（我上传到tablename）和运行heroku pg之后的“select * from tablename”：psql显示了我想要的所有数据。有谁知道为什么这种关系没有被认可？ 谢谢！ After running db:migrate I get this issue 编辑：这是heroku日志的输出（experimentInfo是表名）
