AbiWord：[文件路径/测试]不是有效的文件名？

问题描述

致力于将文档从 docx，doc转换为pdf 。了解 Abiword ，它可以将文档从一种文件格式转换为另一种文件格式。将python与os模块一起使用，该模块应该执行我的命令。这可以正常工作，没有空格文件，但是只要有个带有空格的文件，就会出现此错误。试图打印命令并检查它是对还是错，但是命令是正确的。

def saveDocx(files,user):
destination = Path.joinpath(MEDIA_ROOT,user,"trash")
current_doc_files = list()
for file in files:
    fs = FileSystemStorage(location=destination)
    filename = fs.save(file.name,file)
    filename = os.path.join(destination,filename)
    current_doc_files.append(filename)
print("doc files---->",current_doc_files)
return current_doc_files,destination

def convToPdf(current_doc_files,user):
    current_pdf_files = list()
    for file in current_doc_files:
        cmd = "abiword --to=pdf {}".format(file)
        print("----cmd----",cmd)
        try:
            os.system(cmd)
            pdf_file_name = os.path.splitext(file)[0] + '.pdf'
            print("converted ",pdf_file_name)
            current_pdf_files.append(pdf_file_name)
        except Exception as ex:
            print("--------Exception--------")
            print(ex)
    return current_pdf_files

在pythonanywhere上创建Web应用程序，他们提供了Abiword文字处理器。看一下输出 当文件没有空格

doc files----> ['/home/trash/test.docx']

图片中包含空格的文件时，出现以下错误

doc files----> ['/home/trash/test test.docx']

我有另一种解决方案，用下划线替换空格，但想知道这是怎么回事。
