我得到了脚本 chmod +x
但是当我输入终端 sdfgdgh 给我错误：
bad interpreter no such file or directory /usr/bin/python

The problem is with your python instalation. Probably your /usr/bin/pythoneither does not exist at all or it is dead symbolic link pointing to non existing python.
问题在于您的 python 安装。可能你的/usr/bin/python要么根本不存在，要么是指向不存在的python的死符号链接。
So first solution is to check if /usr/bin/pythonexists. If so check if it's not dead link and if it is, fix the link to point to existing python intepretter:
所以第一个解决方案是检查是否/usr/bin/python存在。如果是这样，请检查它是否不是死链接，如果是，请修复链接以指向现有的 python 解释器：
cd /usr/bin
sudo ln -fs <full_path_to_existing_python_binary> python
If you can't or don't want to change /usr/bin/pythonbut you have python installed and it's location is recognized by system (i.e. calling pythonfrom shell works) you can try changing your script as a workarround:
如果您不能或不想更改/usr/bin/python但您安装了 python 并且它的位置被系统识别（即python从 shell调用），您可以尝试更改脚本作为解决方法：
#! /usr/bin/env python
print("worked")
This way your script will use python as an interpetter regardless real python location as long as it is in your PATH.
这样你的脚本就会使用 python 作为 interpetter，而不管真正的 python 位置，只要它在你的 PATH 中。
