#!/usr/bin/env python vs #!/usr/local/bin/python
Sep 16, 2010
#!/usr/bin/env python
Will figure out the correct location of python and make that as the interpreter for rest of the script.
#!/usr/local/bin/python
Pointing to python is located at /usr/local/bin/python.
简单说 /env python 就是查找系统环境变量中的 python 并默认选择 path 里第一个。/usr/local/bin/python 就是指定使用这个路径下的 python，可能不同机子不同环境下 python 位置稍有差别，就有可能 /usr/local/bin/python 不存在。
