The following is how I installed it for Python 3x.Go to http://www.crummy.com/software/BeautifulSoup/#Download or https://pypi.python.org/pypi/beautifulsoup4/4.3.2 and download beautifulsoup4-4.3.2.tar.gz.Navigate to the folder where you downloaded the file. Use 7zip to extract the beautifulsoup4-4.3.2.tar.gz file.Double click the beautifulsoup4-4.3.2.tar.gz folder to drill down though the dist folder and then extract the beautifulsoup4-4.3.2.tar file.Double click the beautifulsoup4-4.3.2.tar folder to drill down through yet another beautifulsoup4-4.3.2 folder. Inside the beautifulsoup4-4.3.2 folder you will see the setup.py file.Hold down the Shift key while right clicking anywhere inside the folder and select Open command window here.At the command prompt type: setup.py install and press Enter.When then installation stops running, verify that the package was installed by navigating to the C:\Python34\Lib\site-packages directory. If installed you will see the bs4 directory.Verify that the installation is working by going to Go to Start > All Programs > Python 3.4 > IDLE (Python 3.4 GUI 32 bit) to launch the basic IDE.After the prompt type: >>>from bs4 import BeautifulSoupIf you receive no errors it is working. 这篇关于无法在Windows7的python3.5中安装BeautifulSoup4的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
