Hyperledger Explorer启动失败并通过数据库身份验证

Question

尝试启动Hyperledger Explorer应用程序时遇到问题。我按照here中的说明进行操作，但是在尝试启动该应用程序时仍然失败。

我的config.json文件如下：

我的explorerconfig.json文件：

{
"persistence": "postgreSQL",
"platforms": ["fabric"],
"postgreSQL": {
  "host": "127.0.0.1",
  "port": "5432",
"database": "fabricexplorer",
"username": "rodolfo",
"passwd": ""
},
"sync": {
  "type": "local",
  "platform": "fabric",
  "blocksSyncTime": "3"
}
}

我在日志中遇到的错误是：

postgres://rodolfo:@127.0.0.1:5432/fabricexplorer
error when connecting to db: { error: password authentication failed 
for user "rodolfo"...

已经尝试在PSQL上更改我的用户的密码，并在explorerconfig.json上对其进行修改，但是仍然显示相同的错误。尝试使用空白密码，仍然显示错误。任何指导将不胜感激。
