Python error "import: unable to open X server"
提问by ComputerLocus
I am getting the following errors when trying to run a piece of python code:
尝试运行一段python代码时出现以下错误：
import: unable to open X server `' @ error/import.c/ImportImageCommand/366.
from: can't read /var/mail/datetime
./mixcloud.py: line 3: syntax error near unexpected token `('
./mixcloud.py: line 3: `now = datetime.now()'
The code:
编码：
import requests
from datetime import datetime,date,timedelta
now = datetime.now()
I really lack to see a problem. Is this something that my server is just having a problem with and not the code itself?
我真的没有看到问题。这是我的服务器有问题而不是代码本身的问题吗？

those are errors from your command shell. you are running code through the shell, not python.
这些是来自您的命令外壳的错误。您正在通过 shell 运行代码，而不是 python。
try from a python interpreter ;)
从 python 解释器尝试；)
$ python
Python 2.7.5+ (default, Sep 19 2013, 13:48:49)
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> from datetime import datetime,date,timedelta
>>>
>>> now = datetime.now()

if you are using a script, you may invoke directly with python:
如果您使用的是脚本，则可以直接使用 python 调用：
$ python mixcloud.py
otherwise, ensure it starts with the proper shebang line:
否则，请确保它以正确的 shebang 行开头：
#!/usr/bin/env python
... and then you can invoke it by name alone (assuming it is marked as executable):
...然后您可以单独按名称调用它（假设它被标记为可执行文件）：
$ ./mixcloud.py

Check whether your #!line is in the first line of your python file. I got this error because I put this line into the second line of the file.
检查您的#! line 位于 python 文件的第一行。我收到此错误是因为我将此行放入文件的第二行。

I got this error when I tried to run my python script on docker with docker run. Make sure in this case that you set the entry point is set correctly:
当我尝试使用docker run在 docker 上运行我的 python 脚本时出现此错误。在这种情况下，请确保您设置的入口点设置正确：
--entrypoint /usr/bin/python
