[已解决]python 关于安装scrapy库 安装出现报错

W鱼蛋W

已安装Anaconda，之前单独安装的python已经卸载了。
在命令行安装scrapy，显示Anaconda中已经存在这个库了。
但是让检验这个库是否可顺利运行时，发生了错误

1. C:\Users\w>scrapy -h
   
2. Traceback (most recent call last):
   
3.   File "d:\anaconda\lib\runpy.py", line 193, in _run_module_as_main
   
4.     "__main__", mod_spec)
   
5.   File "d:\anaconda\lib\runpy.py", line 85, in _run_code
   
6.     exec(code, run_globals)
   
7.   File "D:\Anaconda\Scripts\scrapy.exe\__main__.py", line 5, in <module>
   
8.   File "d:\anaconda\lib\site-packages\scrapy\__init__.py", line 34, in <module>
   
9.     from scrapy.spiders import Spider
   
10.   File "d:\anaconda\lib\site-packages\scrapy\spiders\__init__.py", line 10, in <module>
    
11.     from scrapy.http import Request
    
12.   File "d:\anaconda\lib\site-packages\scrapy\http\__init__.py", line 11, in <module>
    
13.     from scrapy.http.request.form import FormRequest
    
14.   File "d:\anaconda\lib\site-packages\scrapy\http\request\form.py", line 11, in <module>
    
15.     import lxml.html
    
16.   File "d:\anaconda\lib\site-packages\lxml\html\__init__.py", line 54, in <module>
    
17.     from .. import etree
    
18. ImportError: DLL load failed: 找不到指定的模块。

删除这个库后，重新安装还是这样。
在命令行构建一个scrapy工程的时候，也是发生如下报错，不知该如何解决

1. C:\Users\w>E:
   
2. 
   
3. E:\>cd Python
   
4. 
   
5. E:\Python>scrapy startproject python123demo
   
6. Traceback (most recent call last):
