Odoo 12 python 写入 xls 文件失败（PermissionError: [Errno 13] Permission denied :)

Question

我从 odoo 生成 xls 文件，代码在我的笔记本电脑上工作，但在服务器机器上却不行 我尝试了这两个命令：

1- sudo chmod -R 777 /usr/local/lib/python3.6/

2-sudo chown -R 777 /odoo/

但什么都没有改变

感谢您的帮助

Answer 1

我会坚持使用 Odoo 本身用于其报告或导出文件的解决方案：使用 /tmp 作为临时（双关语）文件目录。在“正常”或“常规”服务器配置中，几乎所有应用程序都可以使用此目录，而无需考虑文件访问。

因此，您必须更改自定义模块用于创建 Excel 文件的路径。 （无法进一步提供帮助，因为您没有分享您的代码）
