从crontab运行python时出现问题-“无效的python安装" [英] Problem running python from crontab - "invalid Python installation"

问题描述

我在linux机器上安装了python 2.7，我正在尝试通过crontab计划python脚本.该脚本可以从命令行正常运行，但是通过cron运行时，我得到了:

I have python 2.7 installed on my linux box, and I'm trying to schedule a python script via crontab. The script works fine from the command line, however when running via cron I get:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site.py", line 553, in <module>
    main()
  File "/usr/local/lib/python2.7/site.py", line 535, in main
    known_paths = addusersitepackages(known_paths)
  File "/usr/local/lib/python2.7/site.py", line 268, in addusersitepackages
    user_site = getusersitepackages()
  File "/usr/local/lib/python2.7/site.py", line 243, in getusersitepackages
    user_base = getuserbase() # this will also set USER_BASE
  File "/usr/local/lib/python2.7/site.py", line 233, in getuserbase
    USER_BASE = get_config_var('userbase')
  File "/usr/local/lib/python2.7/sysconfig.py", line 535, in get_config_var
    return get_config_vars().get(name)
  File "/usr/local/lib/python2.7/sysconfig.py", line 434, in get_config_vars
    _init_posix(_CONFIG_VARS)
  File "/usr/local/lib/python2.7/sysconfig.py", line 298, in _init_posix
    raise IOError(msg)
IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory)

我看到/usr/include/python2.7不存在，但是/usr/local/include/python2.7/存在.安装python时，我是否犯了一个错误?

I see that /usr/include/python2.7 does't exist, but /usr/local/include/python2.7/ does. Did I make a mistake while installing python?

推荐答案

您可能只安装了2个版本，其中一个版本已损坏.如果您的cron只是直接调用python而不是特定路径，则您的PATH可能在/usr/local/bin之前包含/usr/bin(这是典型的)-因此在您的cron中，指定要使用的python或删除现有的python /usr/bin中的一个，并将/path/to/good/python链接到/usr/bin/python.

You probably just have 2 versions installed, one of which is broken. If your cron is just directly calling python instead of a specific path, your PATH probably contains /usr/bin before /usr/local/bin (which is typical) - so in your cron, specify which python to use, or remove the existing one in /usr/bin and symlink /path/to/good/python to /usr/bin/python.

从头开始，只需重新阅读并在命令行中看到它正常工作即可. python-dev可能是要走的路.抱歉！

scratch that, just re-read and saw that it works fine from the command line. python-dev is probably the way to go. Sorry!
