Question

我正在运行一个带有flask和mod_wsgi的apache2服务器。

在我的烧瓶脚本中，我有一个创建新目录的函数：

def updateDir():
    dbData = News.query.all()
    for row in dbData:
        rowLink = createLink(row.id, row.title)
        finalPath = "static/img/posts/{}".format(rowLink)
        os.makedirs(finalPath, exist_ok=True)

当我尝试运行脚本时，它会显示此回溯：

ERROR in app: Exception on /refresh [GET]

     mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: 'static'

我已经使用www-data权限写入'static'文件夹，但仍然显示错误。

如果我没有涵盖所有内容以帮助我，请随时提问。

不要使用相对路径名。该进程的当前工作目录通常不在您的代码所在的位置。您需要计算相对于某个锚点的绝对路径。参见：

http://modwsgi.readthedocs.io/en/develop/user-guides/application-issues.html#application-working-directory

我如何修复“PermissionError：[Errno 13]权限被拒绝：'静态'”？
