在macOS上编辑PYTHONPATH

问题描述：

我的Python3安装失败。我相信这可能是由于我的$ PYTHONPATH需要清理。我如何编辑PYTHONPATH（我不知道它在哪里）。在macOS上编辑PYTHONPATH

我能得到什么，当我运行python3：

➜ ~ python3 
Failed to import the site module 
ImportError: bad magic number in 'site': b'\x03\xf3\r\n'

$ PYTHONPATH

➜ ~ python -c "import sys; print '\n'.join(sys.path)"

一个选项来尝试，打开'Terminal'，和输入'echo $ PYTHONPATH'会告诉你它是否已经在你的系统上定义了。如果有，请检查它的定义位置（可能在〜/ .profile，〜/ .bashrc或〜/ .bash_profile等），这样快速的'grep PYTHONPATH〜/ .bash *'或'grep PYTHONPATH〜/.profile'可能会显示变量定义。（[本问答]（https://unix.stackexchange.com/questions/813/how-to-determine-where-an-environment-variable-came-from）也可能有帮助）。如果该终端命令返回一个空行，请创建或编辑其中一个文件并添加您想要的“$ PYTHONPATH”定义 – davedwards

尝试：

export PYTHONPATH=$PYTHONPATH:/Users/username/pymodules export PATH=$PATH:/Users/username/pymodules
