解决EasyOCR运行时PIL.Image无ANTIALIAS属性的AttributeError问题

问题背景 #

使用EasyOCR识别程序截图文本，已通过pip install easyocr完成安装，执行识别代码时触发AttributeError，卸载重装EasyOCR后问题依旧。

代码示例 #

def text_recognition(im, languages):
    reader = easyocr.Reader(languages)
    language = reader.readtextlang(im, paragraph=True)
    if language == 'en':
        result = reader.readtext(im, paragraph=True)
        print(result)
        return result
text = text_recognition('screenshot1.png', ['en', 'ru'])

错误信息 #

AttributeError: module 'PIL.Image' has no attribute 'ANTIALIAS'

已尝试操作 #

pip uninstall easyocr
# 输入y确认卸载
pip install easyocr

错误原因 #

PIL（Pillow）在10.0.0版本中，将Image.ANTIALIAS重命名为Image.LANCZOS，而当前使用的EasyOCR版本未适配该变更，导致代码调用旧常量时触发属性不存在错误。

解决方案 #

方案1：降级Pillow到兼容版本 #

执行以下命令，将Pillow安装到10.0.0以下的稳定版本：

pip install pillow<10.0.0

方案2：修改EasyOCR源码临时修复 #

找到报错路径中的utils.py文件（示例路径：venv\Lib\site-packages\easyocr\utils.py），定位到第576行，将Image.ANTIALIAS替换为Image.LANCZOS，保存后重新运行代码。

方案3：升级EasyOCR到最新版本 #

部分新版本EasyOCR已修复该兼容问题，执行升级命令：

pip install --upgrade easyocr
