Python项目相关路径配置

Posted on | In
  1. python相关环境变量
  • PYTHONPATH : PYTHONPATH是Python搜索路径，默认我们import的模块都会从PYTHONPATH里面寻找。
  • PYTHONSTARTUP: Python启动后，先寻找PYTHONSTARTUP环境变量，然后执行此变量指定的文件中的代码。
  • PYTHONCASEOK: 加入PYTHONCASEOK的环境变量, 就会使python导入模块的时候不区分大小写.
  • PYTHONHOME: 另一种模块搜索路径。它通常内嵌于的PYTHONSTARTUP或PYTHONPATH目录中，使得两个模块库更容易切换。

  1. 配置LD_LIBRARY_PATH
    LD_LIBRARY_PATH is used by your program to search for directories containing the libraries after it has been successfully compiled and linked.

    >>> vim  ~/.bashrc
    ......
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
    >>> source ~/.bashrc
    >>> 重启进程
