使用 pycharm 对 Python 项目调试遇到非常诡异的现象

  •

    这是一个创建于 1842 天前的主题,其中的信息可能已经有所发展或是发生改变。

    调试项目: https://github.com/WhaleShark-Team/cobra

    脚本命令:python cobra.py -t /root/php/dvwa/vulnerabilities/sqli_blind/ -d

    我在公司开发机上面 pipenv 搭建使用的是 py3.7,一开始我是用的 pycharm 远程调试,Run 没有任何问题,但是 Debug 会在进程池代码 multiprocessing.Pool()附近报错 KeyboardInterrupt 吗,实际上我什么也没有做,Run 没事儿,Debug 点一下就会自动中断。

    ssh://[email protected]:22/root/.local/share/virtualenvs/cobra-CV_8c13e/bin/python -u /root/.pycharm_helpers/pydev/pydevd.py --multiproc --qt-support --client '0.0.0.0' --port 40819 --file /root/python/cobra/cobra.py -t /root/php/dvwa/vulnerabilities/sqli_blind/ -d

    因为看不懂报错代码,所以我就使用了我搭建在 vmware 中的虚拟机 centos7,然后同样使用 pipenv 安装了 py3.7 的虚拟环境,但是诡异得是 Run 都会产生问题了,而且报错也和之前远程调试 Debug 不一样,

    但是我直接在 centos 命令行下运行 pycharm 运行的命令是没有问题的,我是真不知道咋办了,只能打扰求助各位前辈,愿意花 20 块钱求教到底为何,聊表心意,困扰了一晚上。

    pycon 群里刘师傅说了一个问题,“你用的是虚拟环境下的 python,为啥报错目录是 /usr/local/python3 呢”
    我也感觉好奇怪,按道理来说,报错应该是在虚拟环境下的吧?!

    感觉是 log.py 文件的问题
    ```
    def emit(self, record):
    try:
    message = stdout_encode(self.format(record))
    stream = self.stream

    if not self.is_tty:
    if message and message[0] == "\r":
    message = message[1:]
    stream.write(message)
    else:
    self.output_colorized(message)
    stream.write(getattr(self, 'terminator', '\n'))

    self.flush()
    except (KeyboardInterrupt, SystemExit):
    raise
    except IOError:
    pass
    except Exception as e:
    self.handleError(record)
    ```
    这个改成
    ```
    def emit(self, record):
    try:
    message = stdout_encode(self.format(record))
    stream = self.stream

    if not self.is_tty:
    if message and message[0] == "\r":
    message = message[1:]
    stream.write(message.decode(sys.stdout.encoding))
    else:
    self.output_colorized(message)
    stream.write(getattr(self, 'terminator', '\n'))

    self.flush()
    except (KeyboardInterrupt, SystemExit):
    raise
    except IOError:
    pass
    except Exception as e:
    self.handleError(record)
    ```
    感觉是 pycharm log 走的
    ```
    if not self.is_tty:
    if message and message[0] == "\r":
    message = message[1:]
    stream.write(message.decode(sys.stdout.encoding))
    ```
    而 terminator 走的是
    ```
    else:
    self.output_colorized(message)
    ```

    以前遇到过 pycharm 调试 asyncio,调试时下断点,pycharm 偶发退出,但是提前下好断点,再启动调试就 OK。

    @chenqh 多谢师傅回复,没想到确实是这样,stream.write(message)改成 stream.write(message.decode('utf-8'))就可以了。

    @chenqh 但是我发现在虚拟机中使用 pycharm 调试,在使用了进程池的附近也会报一样的 KeyboardInterrupt 错误,看来不是远程调试的问题,不过师傅已经帮我解决了一个问题,师傅请问微信或者 qq 私聊或者发我吧,我给师傅转钱,我的 qq 是 9614 六 2392
    @lniwn 提前下好,下到出错的后面了,也不行呢,感谢师傅。

    最后发现好像是 py3.7 的问题,换成 py2.7 可以了。

    经测试,py3.6.8 亦可,大概率真是 py3.7 的问题。。

    py3.7 好像真的有些问题,我 pyltp 都装不了,只能把 python 版本改成 3.6 的才装上去了。
