Question

是否可以在PyCharm中远程调试诅咒程序？如何设置？

我按照PyCharm 4.0.8指令，将其添加到＆＃34; EXAMPLE.py＆＃34;来自＆＃34; npyscreen-4.8.7＆＃34;。

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

总是在＆＃34; setupterm＆＃34;：

中遇到错误

$ 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改变了环境＆＃34; TERM＆＃34;来自＆＃34; xterm＆＃34;到＆＃34; emacs＆＃34;。这可以通过一个小测试程序来验证。

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"

如果使用＆＃34; pdevd＆＃34;删除这两行，程序会成功。＆＃34; TERM＆＃34;打印出来的是＆＃34; xterm＆＃34;。
如果将第一个参数更改为＆＃34; setupterm＆＃34;进入＆＃34; term='xterm'＆＃34;，即使使用＆＃34; pydevd＆＃34;它成功了。

我想问题是如何让＃34; pydevd＆＃34;设置正确的＆＃34; TERM＆＃34;？

Answer 1

虽然其中一个答案可能是：改变/usr/lib/python2.6/curses/__init__.py强制TERM，如：

def initscr():
    import _curses, curses
    # we call setupterm() here because it raises an error
    # instead of calling exit() in error cases.
    _os.environ['TERM'] = 'xterm' ##hack force 'xterm' for pydevd debugging.
    setupterm(term=_os.environ.get("TERM", "unknown"),
              fd=_sys.__stdout__.fileno())
    stdscr = _curses.initscr()
    for key, value in _curses.__dict__.items():
        if key[0:4] == 'ACS_' or key in ('LINES', 'COLS'):
            setattr(curses, key, value)

    return stdscr

更改“TERM”的原始来源位于：

$ head plugins/org.python.pydev_4.0.0.201504132356/pysrc/pydev_ipython_console.py 
import sys
from pydev_console_utils import BaseInterpreterInterface

import os

os.environ['TERM'] = 'emacs' #to use proper page_more() for paging


# Uncomment to force PyDev standard shell.
# raise ImportError()

Answer 2

这个各种提示指出了pydevd中TERM的硬编码设置，这使我得到了这个序列，这对我有用：

#
# 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'
