Study notes: Python3,pip Installing third-party libraries (2017)

Pip to Python is like NPM for node. JS, as well as the package control for Sublime Text

Since the version after python3.4 comes with a pip, it needs to be upgraded before it can be used:
c:\python3\scripts\> python-m pip install--upgrade pip

# View the package that is installed c:\python3\scripts\> python pip.exe list#  Viewa package c:\python3\scripts\>  Python pip.exe show bs4# updates to the installed toolkit c:\python3\scripts\> python pip.exe install-U bs4< /c8>#  Install packagec:\python3\scripts\> python pip.exe install packagename#  Uninstallpackage c:\python3\scripts\> python pip.exe uninstall PackageName

C:\Python3\Lib\site-packages installed libraries are saved here.

You can then install the other libraries directly via PIP, such as installing the requests library, the correct posture:

c:\python3\scripts\> Python Pip.exe Install requests (introduction of third-party library requests)
c:\python3\scripts\> python pip.exe Install Pdfkit (introduction of third-party library Pdfkit)--Operation PDF
c:\python3\scripts\> python pip.exe Install Scrapy (introduction of third-party library Scrapy)-error, lack of VC + +
c:\python3\scripts\> python pip.exe Install Pdfkit (introduction of third-party library Django)
c:\python3\scripts\> python pip.exe Install Pymysql (introduction of third-party library Pymysql)-Database connection library, connection to MySQL
c:\python3\scripts\> python pip.exe Install cookies (introducing third-party libraries cookies2.2.1)
c:\python3\scripts\> python pip.exe uninstall Image (delete third-party library Image1.5.5)
c:\python3\scripts\> python Pip.exe Install pillow (introduction of third-party library PIL) since PIL only supports Python 2.7, plus years of disrepair, a group of volunteers created a compatible version on the basis of PIL, Named Pillow, which supports the latest Python 3.x and adds many new features, so we can install it directly using pillow
c:\python3\scripts\> python pip.exe Install XLWT (introduction of third-party library XLWT)--Write Excel
c:\python3\scripts\> python pip.exe Install xlrd (introduction of third-party library XLRD)--Read Excel
c:\python3\scripts\> python pip.exe Install cx_oracle (introduction of third-party library cx_oracle)--oracle database, not installed, there is a problem.
c:\python3\scripts\> python pip.exe Install BS4 (introduction of third-party library BS4)
