运行 paste 时出现语法错误？

Question

No idea what happened, but all of a sudden, paster stopped working on my server (working with virtualenv and pyramid). Tried reinstalling everything but didn't work - same error again:

Traceback (most recent call last):
  File "bin/paster", line 7, in ?
    sys.exit(
  File "/home/user/webapps/myapp/htdocs/lib/python2.4/site-packages/PasteScript-1.7.3-py2.4.egg/paste/script/command.py", line 83, in run
    command = commands[command_name].load()
  File "/home/user/webapps/myapp/htdocs/lib/python2.4/site-packages/setuptools-0.6c11-py2.4.egg/pkg_resources.py", line 1954, in load

    with open(filename) as f:
            ^
SyntaxError: invalid syntax

What is happening to me?

Answer 1

You are using Python 2.4. It does not have the with statement. It only came in Python 2.5.

Update your version of Python.
