我在运行Redmine应用程序的Puma Application Server上出错.美洲狮正确快速地启动下一个http调用返回此错误...我没有在Google上找到答案如何处理这个问题.

这是错误消息:

以下是有关此服务器的信息:

这是错误：

$  psql -h localhost -U kMbjQ6pR9G  -d fzvqFILx0d
Password for user kMbjQ6pR9G: 
psql: FATAL:  password authentication failed for user "kMbjQ6pR9G"
FATAL:  password authentication failed for user "kMbjQ6pR9G"

我可能缺少使用新 PostgreSQL 的配置步骤。

这是我尝试使用自己的数据库创建新用户的命令行：

sudo -u postgres bash -c "psql -c \"CREATE USER $USER WITH PASSWORD '$PASSWORD';\"" &&
sudo -u postgres bash -c "psql -c \"CREATE DATABASE $DB;\"" &&
sudo -u postgres bash -c "psql -c \"GRANT ALL PRIVILEGES ON DATABASE $DB to $USER;\"" &&

这是 PostgreSQL 配置：

$ sudo grep -v …

我在插入 TCPDF 图像时遇到问题。

这是我正在使用的代码：

$this->Image($this->data['logo'], PDF_MARGIN_LEFT, 5, 60, 20, '', '', 'M', true);

我已将调整大小设置为 true，但 TCPDF 库不考虑图像比例。

如何强制保留图像比例？

有关信息，我正在使用 TCPDF 6.2.8 (2015-04-29)。

感谢您的支持，大卫。
