问题描述

我只是想在 Python 中读取我的 json 文件.当我这样做时，我在正确的文件夹中；我在下载中，我的文件名为Books_5.json".但是，当我尝试使用 .read() 函数时，我得到了错误

I am simply trying to read my json file in Python. I am in the correct folder when I do so; I am in Downloads, and my file is called 'Books_5.json'. However, when I try to use the .read() function, I get the error

OSError: [Errno 22] Invalid argument

这是我的代码:

import json
config = json.loads(open('Books_5.json').read())

这也会引发同样的错误:

This also raises the same error:

books = open('Books_5.json').read()

如果有帮助，这是我的数据的一小部分:

推荐答案

看来这是文件太大时出现的某种错误(我的文件是~10GB).一旦我使用 split 将文件分成 200 k 行，.read() 错误就会消失.即使文件不是严格的 json 格式也是如此.

It appears that this is some kind of bug that occurs when the file is too large (my file was ~10GB). Once I use split to break up the file by 200 k lines, the .read() error goes away. This is true even if the file is not in strict json format.
