QR 码未出现在报告中。为什么？

Question

我尝试打印一个简单的二维码图像，但无法打印。我使用了 code that I found in the documentation 但它没有用。我还需要什么吗？我安装了 reportlabs 库。

<img t-att-src="'/report/barcode/QR/%s' % 'My text in qr code'" />

<img t-att-src="'/report/barcode/?type=%s&amp;value=%s&amp;width=%s&amp;height=%s'%('QR', 'text', 200, 200)"/>

我检查了日志文件，发现了这个错误：

我也安装了软件包 ttf-mscorefonts-installer

嗯，我在Odoo论坛找到了解决方法，here:

在 /path/to/your/python/site-packages/reportlab/fonts 这些文件中下载并解压缩

重启服务器试试
