OSError：[Errno 22]当我尝试.read（）一个json文件时 [英] OSError: [Errno 22] when I try to .read() a json file

问题描述

我只是想用Python读取json文件。这样做时，我位于正确的文件夹中；我正在下载中，我的文件名为 Books_5.json。但是，当我尝试使用.read（）函数时，出现错误

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())

这也会引发相同的错误：

This also raises the same error:

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

如果有帮助，这只是我数据看起来的一小段像这样：

推荐答案

似乎这是文件太大（我的文件约为10GB）时发生的错误。一旦我使用 split 分解了文件减少20万行， .read（）错误就消失了。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.
