Scrapy deltafetch安装

Question

安装scrapy-deltafetch时使用

pip install scrapy-deltafetch

我碰到了一个凹凸：

PS C:\python\Scripts> pip install bsddb3 --no-cache-dir
Collecting bsddb3
  Downloading bsddb3-6.2.5.tar.gz (237kB) 100%
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
     File "<string>", line 1, in <module>
     File "C:\Users\XYZ\AppData\Local\Temp\pip-build-ui_ns07z\bsddb3\setup.py", line 42, in <module>
    import setup3
     File "C:\Users\XYZ\AppData\Local\Temp\pip-build-ui_ns07z\bsddb3\setup3.py", line 382, in <module>
    with open(os.path.join(incdir, 'db.h'), 'r') as f :
    FileNotFoundError: [Errno 2] No such file or directory: 'db/include\\db.h'

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\XYZ\AppData\Local\Temp\pip-build-ui_ns07z\bsddb3\

我已经为Windows安装了berkley db x86，并通过忽略pip缓存目录再次尝试安装。问题依然存在。

我究竟做错了什么？

请帮忙。

由@has回答：

另一种方法是通过下载包文件，.whl将其粘贴到C:\python\Scripts文件夹中。然后运行pip install {package_filename}.whl
