使用时候报错

[KiraJYQiu]

首先我在安装的时候报错，后来删了在requirements.txt里的指定版本才安装成功，看来其中一些插件的旧版本已经不提供安装。

然后在使用过程中也报错了，log如下

D:\Program Files Green\ChangePDFContrast>"D:\Program Files Green\ChangePDFContrast\main.py"
======第一步：分解=====
正在调用PDF转PIL数组的库函数，如果你电脑内存太小且PDF太大，有可能内存崩掉，那跟我没关系，自己找pdf2img的作者哭去，反正我32G不慌...
耐心等一会儿...
分解完成,用时0.94秒
======第二步：图片处理=====
正在处理第1张图片...
