Python 找不到 LibTIFF 库，即使已经安装了 LibTIFF

Question

I need LibTIFF in order to compile TIFF images in PIL (as mentioned here in the documentation).

I started with a simple pip install LibTIFF . After that installed successfully I tried running my code, which includes import LibTIFF - but got the following error:

Traceback (most recent call last):
  File "tile_fetch_4.py", line 14, in <module>
    from libtiff import tiff
  File "C:\Users\i\AppData\Local\Programs\Python\Python38\lib\site-packages\libtiff\__init__.py", line 20, in <module>
    from .libtiff_ctypes import libtiff, TIFF, TIFF3D
  File "C:\Users\i\AppData\Local\Programs\Python\Python38\lib\site-packages\libtiff\libtiff_ctypes.py", line 46, in <module>
    raise ImportError('Failed to find TIFF library. Make sure that libtiff '
ImportError: Failed to find TIFF library. Make sure that libtiff is installed and its location is listed in PATH|LD_LIBRARY_PATH|.. 

Yet, when running pip instal libtiff :

Requirement already satisfied: libtiff in c:\users\i\appdata\local\programs\python\python38\lib\site-packages (0.4.2)

Why doesn't it recognize LibTIFF?
