使用 libreoffice 将 docx 文件转换为 pdf 时显示错误

Question

我以 html 形式上传 docx 文件，然后我想在 ubuntu 服务器中将此文件转换为 pdf，但它在 /add-document 处显示类似 CalledProcessError 的错误 命令 '['libreoffice', '--headless', '--convert-to', 'pdf', '/var/www/html/dev/media/documents/Lavender_Bay_Boatshed_Website_Testing_61gWm6r.docx', '--outdir', '/var/www/html/dev/media/documents/Lavender Bay Boatshed Website Test.pdf']' 返回非零退出状态 77。

Answer 1

我们可能需要一些额外的信息。尝试从以下几点开始：

1- 验证要转换的文件的路径 (

obj.document.path

) 是否正确。您只需在调用 libreoffice 之前添加

os.path.isfile(obj.document.path)

即可完成此操作。

2- 确保您的环境中安装了 libreoffice：

libreoffice --version

3-尝试使用

--convert-to pdf:writer_pdf_Export

而不仅仅是

--convert-to pdf

4-确保输出目录存在

5-确保没有打开 libreoffice 的 GUI 实例
