python curses远程调试pdevd错误在setupterm [英] python curses remote debugging pdevd error in setupterm

问题描述

可以在PyCharm中远程调试诅咒程序吗？如何设置？

Is it possible to debug a curse program remotely in PyCharm? How to set it up?

我遵循PyCharm 4.0.8指令，将其添加到 EXAMPLE.py 从 npyscreen-4.8.7 。

I followed the PyCharm 4.0.8 instruction, added this to the "EXAMPLE.py" from "npyscreen-4.8.7".

import pydevd
pydevd.settrace('localhost', port=8899, stdoutToServer=False, stderrToServer=True)

总是在 setupterm ：

$ PYTHONPATH=~/bin/pycharm-debug.egg python EXAMPLE.py
Traceback (most recent call last):
  File "EXAMPLE.py", line 34, in <module>
    App.run()
  File "/home/.../npyscreen-4.8.7/npyscreen/apNPSApplication.py", line 30, in run
    return npyssafewrapper.wrapper(self.__remove_argument_call_main)
  File "/home/.../npyscreen-4.8.7/npyscreen/npyssafewrapper.py", line 41, in wrapper
    wrapper_no_fork(call_function)
  File "/home/.../npyscreen-4.8.7/npyscreen/npyssafewrapper.py", line 83, in wrapper_no_fork
    _SCREEN = curses.initscr()
  File "/usr/lib64/python2.6/curses/__init__.py", line 33, in initscr
    fd=_sys.__stdout__.fileno())
_curses.error: setupterm: could not find terminal

问题是pydevd将环境TERM从xterm更改为emacs。这可以通过一点测试程序来验证。

---

The problem is that pydevd changed environment "TERM" from "xterm" to "emacs". This can be verified by a little test program.

import pydevd
pydevd.settrace('localhost', port=8899, stdoutToServer=False, stderrToServer=True)
import os as _os
import sys as _sys
import curses
print " my term: ", _os.environ.get("TERM", "unknown"), "\n"
print " my fd:   ", _sys.__stdout__.fileno(), "\n"
print "\n  ok  1  \n"
curses.setupterm(term=_os.environ.get("TERM", "unknown"),
#curses.setupterm(term='xterm',
                fd=_sys.__stdout__.fileno())
print "\n  ok  2  \n"

• 如果删除两行 pdevd ，程序成功，打印出来的 TERM 是 xterm 。


• 如果将第一个参数更改为 setupterm 到 term ='xterm'，即使使用 pydevd 也可以成功。


• If removing the two lines with "pdevd", the program succeeds. The "TERM" it prints out is "xterm".
• If change the 1st argument to "setupterm" into "term='xterm'", even with "pydevd" it succeeds.

我想问题是如何使用 pydevd 设置更正t TERM

I guess the question is how to have "pydevd" setup the correct "TERM"?

推荐答案

这个各种提示指出了硬编码在pydevd中设置TERM导致我的这个顺序，这对我有用：

This various hints pointing out the hardcoded setting of the TERM in pydevd led me to this sequence, which works for me:

#
# From the instructions in the PyCharm remote debug setup screen,
# add this to your code before curses is initialised.
#
import pydevd
pydevd.settrace('localhost', port=8899)
#
# And then to fixup the broken setting in pydevd...
#
os.environ['TERM'] = 'xterm'
