• 异常：

• AttributeError                            Traceback (most recent call last)
  <ipython-input-5-880e5dfa627c> in <module>
        1 def install(package):
        2     pip.main(["install", package])
  ----> 3 install("syslog_parse")
  
  <ipython-input-5-880e5dfa627c> in install(package)
        1 def install(package):
  ----> 2     pip.main(["install", package])
        3 install("syslog_parse")
  
  AttributeError: module ‘pip‘ has no attribute ‘main‘

   

• 代码：

• def install(package):
      pip.main(["install", package])
  
  def uninstall(package):
      pip.main(["uninstall -y", package])

   

• 解决：这是因为pip不同版本的情况：

• def install(pkg):
      try:
          from pip._internal import main
      except Exception:
          from pip import main
      return main(["install", pkg])
  
  def uninstall(pkg):
      try:
          from pip._internal import main
      except Exception:
          from pip import main
      return main(["uninstall -y", pkg])
