阿新 • • 發佈：2018-11-11
正文開始:
1. yum -y install openssl*
(pip依賴ssl環境)
2.編譯安裝python3
下載地址:https://www.python.org/ftp/python/
1 tar zxvf Python-3.5.2.tgz 2 cd Python-3.5.2 3 ./configure 4 make && make install安裝步驟
3.安裝完成後預設就有pip3了. 4.安裝完成可以裝個模組試試
1 [[email protected] Python-3.5.2]# pip3 install pymysql 2 Collecting pymysql 3 Downloading PyMySQL-0.7.9-py3-none-any.whl (78kB) 4 100% |████████████████████████████████| 81kB 6.3kB/s 5 Installing collected packages: pymysql 6 Successfully installed pymysql-0.7.9 7 You are using pip version 8.1.1, however version 9.0.1 is available. 8 You should consider upgrading via the 'pip install --upgrade pip' command.
上面提示有新版本了 可以升級.
使用它提示的命令就可以升級pip3了..
但是注意要把pip命令替換成pip3
1 [[email protected] Python-3.5.2]# pip3 install --upgrade pip2 Collecting pip 3 Downloading pip-9.0.1-py2.py3-none-any.whl (1.3MB) 4 100% |████████████████████████████████| 1.3MB 3.2kB/s 5 Installing collected packages: pip 6 Found existing installation: pip 8.1.1 7 Uninstalling pip-8.1.1: 8 Successfully uninstalled pip-8.1.1 9 Successfully installed pip-9.0.1 10 [[email protected] Python-3.5.2]# pip3 --version 11 pip 9.0.1 from /usr/local/lib/python3.5/site-packages (python 3.5)
升級完成
PS:
如果使用pip3安裝外掛的時候提示:
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
是因為系統缺少openssl-devel包
yum install openssl-devel -y 安裝一下即可.
再按照上面的方法重新 編譯一下即可.
