exifread.process_file（） 会抛出 “KeyError： 'hdlr'” 和 “NoParser： hdlr Output is truncated.” 对于 HEIC 图像，即使 exifread 可以处理 HEIC
exifread.process_file() throws "KeyError: 'hdlr'" and "NoParser: hdlr Output is truncated." for a HEIC image even though exifread can deal with HEIC
问：
根据 ExifRead 3.0.0 的指南，该指南说它可以处理 HEIC 图像，以及如何在 Python 中使用 HEIC 图像文件类型的示例，我尝试读取 HEIC 文件的元数据：
p = Path(r'C:\Users\Admin\Pictures\Apple media files\gallery\202204')
l=list(p.glob('**/*.HEIC'))
print(l[0])
# Open image file for reading (must be in binary mode)
f = open(l[0], 'rb')
# Return Exif tags
# tags = exifread.process_file(f)
# tags
exifread.process_file(f)
C:\Users\Admin\Pictures\Apple media files\gallery\202204\IMG_1234.HEIC
---------------------------------------------------------------------------

170 try:

172 except (IndexError, KeyError) as err:

The above exception was the direct cause of the following exception:

如何使用“exifread”Python 模块获取 HEIC 文件的元数据？

这只是为了分享我在网上找到的解决此问题的内容。检查 HEIC 处理错误：Apple Silicon #4 上的 hdlr。
因此，您应该降级到低于 3.0.0 的版本：
(scrape) C:\Users\Admin>conda install -c conda-forge "exifread<3"
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

## Package Plan ##
environment location: C:\Users\Admin\anaconda3\envs\scrape
added / updated specs:
- exifread[version='<3']
The following packages will be downloaded:

Total: 35 KB
The following packages will be DOWNGRADED:
exifread 3.0.0-pyhd8ed1ab_0 --> 2.3.2-pyhd8ed1ab_0

在 2.3.2 版本中重新启动 Kernel/file/VSCode 以重新加载 exifread，它可以工作：
