mac 安装selenium遇到的问题

1.mac系统本身带有Python2.7,想要安装Python3.5,需自行下载并安装

  安装Python3.5后,需要安装pip 和setup

2.安装好pip后安装selenium,具体命令如下:

 pip3 install -U selenium

  

  总是报错,具体信息如下:

   Could not fetch URL https://pypi.python.org/simple/selenium/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert     protocol version (_ssl.c:646) - skipping

   Could not find a version that satisfies the requirement selenium (from versions: )

   No matching distribution found for selenium

   You are using pip version 9.0.1, however version 10.0.1 is available.

   You should consider upgrading via the 'pip install --upgrade pip' command.

 
  根据信息提示,需要升级pip, 命令如下

 pip install --upgrade pip

 

  依然报错,具体如下:

   Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert         protocol version (_ssl.c:646) - skipping

 

3.解决方法:网络上看了很多贴纸,最后FQ发现使用curl来升级pip,命令如下:

  

  curl https://bootstrap.pypa.io/get-pip.py | python3

 

  等待下载完成就可以了,perfect!

 

  再输入安装selenium的命令,即可成功。

  

  pip3 install -U selenium

 

  截图如下: 

 

 

总结:Python下下载相应的库时,提示验证ssh证书是否正确时,使用“curl https://bootstrap.pypa.io/get-pip.py | python3”升级pip,然后再下载安装即可成功。
