wkhtmltopdf 失败（错误代码：-8）。消息：b" odoo 12

Question

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

此问题仅适用于 Odoo 12 版本，但对于以前的版本它运行良好.. 此 link 将显示警告消息：Wkhtmltopdf warning

这是日志：

请帮帮我..

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

问题出在字体上。在 Odoo12 中，Bootstrap 4 的默认字体是 Noto Color Emoji，因此，当您生成报告时，wkhtmltopdf 会崩溃。在这个包之后你将拥有这个字体。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
