[英]Python script won't run
I have some scripts in the folder ~/Scripts which I have added to the path. 我在路径中添加了〜/ Scripts文件夹中的一些脚本。 So I tried to test if I can run them, just by calling them. 所以我试着通过调用它们来测试我是否可以运行它们。 I have python 3.1 over Linux Mint 11. 我在Linux Mint 11上有python 3.1。
user@pc ~/Scripts $ python aek.py
AEK
user@pc ~/Scripts $ aek.py
/home/user/Scripts/aek.py: line 1: syntax error near unexpected token `'AEK''
/home/user/Scripts/aek.py: line 1: `print('AEK')'
The code is just this one line: 代码就是这一行:
print('AEK')
You need to add the very first line in your script: 您需要在脚本中添加第一行:
#!/usr/bin/python
Or whatever interpreter you want to use. 或者你想要使用的任何翻译。 If not, the shell (probably bash) will think that it is a shell script and choke. 如果没有,shell(可能是bash)会认为它是一个shell脚本并且阻塞。
If you want to get the python interpreter from the path, do instead: 如果你想从路径中获取python解释器,请改为:
#!/usr/bin/env python
The error is not a python error but a shell error. 该错误不是python错误,而是shell错误。
You should add a shebang line if you don't run them via the python executable. 如果你不通过python可执行文件运行它们,你应该添加一个shebang行。
And it most definitely is not a python2 <-> python3 conflict. 它绝对不是python2 < - > python3冲突。 python2 handles parens here quite well (but there are corner cases where it breaks). python2在这里很好地处理parens(但是有一些它会破坏的角落情况)。
