在pythonanywhere.com上找不到文件 [英] File not found on pythonanywhere.com

问题描述

在 pythonanywhere.com 上，我有一个Django应用.这是 views.py :

On pythonanywhere.com I have a django app. This is views.py:

def literature(request):
    module_dir = os.path.dirname(__file__)
    file_path = os.path.join(module_dir, 'literature.csv')
    with open(file_path, 'r') as f:
        ...

文件 literature.csv 与views.py位于同一目录.但是每次尝试加载页面时，都会得到 FileNotFoundError .相同的构造在本地服务器上正常工作.错误在哪里?

File literature.csv is located at the same directory as views.py. But every time when I try to load the page I get FileNotFoundError. The same construction works normally on local server. Where is the bug?

推荐答案

此 os.path.dirname(__ file __)为您提供了相对路径.在本地服务器上，恰好它对应于正确的路径.在PythonAnywhere上，使用 module_dir 的完整路径.像这样: os.path.abspath(os.path.dirname(__ file __))

This os.path.dirname(__file__) is giving you a relative path. On your local server, it just happens that it corresponds to the correct path. On PythonAnywhere, use the full path for module_dir. Like this: os.path.abspath(os.path.dirname(__file__))
