报告 – wkhtmltopdf失败(错误代码：-8).消息：b“odoo 12

当我想打印任何报告时,我收到此消息：wkhtmltopdf失败(错误代码：-8).消息：b“

这个问题仅适用于Odoo 12版本,但对于以前的版本,它运行良好..
此链接将显示警告消息：Wkhtmltopdf warning

这是日志：

请帮我 ..

解决方法

我找到了解决这个问题的方法.
试试这个：

sudo apt install ttf-mscorefonts-installer
sudo fc-cache -f -v

问题来自字体.在Odoo12中,Bootstrap 4的默认字体是Noto Color Emoji,因此,当您生成报告时,wkhtmltopdf将崩溃.在此包之后,您将拥有此字体.
如果问题仍然存在,请尝试安装 – http://download.odoo.com/fonts/Roboto-Regular.ttf
告诉我它是否有效.您可以在此处跟踪此问题 – https://github.com/odoo/odoo/issues/27487
