没有名为'bs4'的模块错误(No module named 'bs4' Error)

 我打算做网络抓取，但我似乎陷入了第一步。 
 
import urllib.request
from bs4 import beautifulSoup

wiki = "https://en.wikipedia.org/wiki/List_of_state_and_union_territory_capitals_in_India"

page = urllib.urlopen(wiki)

soup = BeautifulSoup(page)

print(soup.prettify())
 
 我写这些行只是为了测试，但它显示了一个错误 
 
Traceback (most recent call last):
  File "C:/python programs/Web Scraping/wiki.py", line 3, in <module>
    from bs4 import beautifulSoup
ModuleNotFoundError: No module named 'bs4'


Process finished with exit code 1
 
 我试图清除它的事情。 
 
 1）pip install beautifulsoup4（尝试使用easy_install） 
 
 2）检查环境变量中的python路径。 我在路径中包含了C：\ python和C：\ python \ Scripts。 
 
 3）尝试从crummy.com下载Beautiful Soup，然后从`python setup.py install命令安装。 
 
 我花了将近一整天的时间来清理它，尝试了几乎所有的解决方案，现在它确实令人沮丧。 但如果有人仍想将其标记为重复，您可以自由地进行复制。 
 
 有什么我错过了吗？ 

I planned to do web scraping, but I seem to be stuck on very first step.
 
import urllib.request
from bs4 import beautifulSoup

wiki = "https://en.wikipedia.org/wiki/List_of_state_and_union_territory_capitals_in_India"

page = urllib.urlopen(wiki)

soup = BeautifulSoup(page)

print(soup.prettify())
 
I wrote these line just to test, but it shows an error that 
 
Traceback (most recent call last):
  File "C:/python programs/Web Scraping/wiki.py", line 3, in <module>
    from bs4 import beautifulSoup
ModuleNotFoundError: No module named 'bs4'


Process finished with exit code 1
 
Things which i tried to clear it.
 
1) pip install beautifulsoup4 (tried this with easy_install as well)
 
2) check the python path in environment variable. i have included both C:\python and C:\python\Scripts in paths.
 
3) Tried downloading Beautiful Soup from crummy.com and then install from `python setup.py install command.
 
I spent almost whole day clearing this out, tried almost every solution and its literally frustrating now. but if anyone still wants to mark it as duplicate you are free to do so.
 
is there anything i have missed ?
