我检查了这个问题并尝试使用celery.contrib.rdb但在执行 telnet 后我被发送到：

我需要在Ubuntu 14.04上从Python 2.6的源代码编译和安装M2Crypto 0.20.1.我现在无法迁移到Python2.7,但我们正在计划.我从https://launchpad.net/~fkrull/+archive/deadsnakes安装了Python2.6 .我安装了libssl-dev和python2.6-dev,文件/usr/include/x86_64-linux-gnu/openssl/opensslconf.h具有644作为权限并由root拥有.

但是setup.py install对于M2Crypto失败如下:

Running setup.py install for M2Crypto

我从 Node.js 世界开始，我注意到节点进程不会自动重启。

四处搜索我发现 nodemon 可以完成这项工作，但我也发现 PM2 是 nodemon 的替代品。那么我应该尝试使用 PM2 进行开发还是将其留在生产中并使用 nodemon 进行开发（这似乎很容易设置）？

我有这门课:

class Point(PointAbstract):
    """
    Class used to expand shapely.geometry.Point functionality
    """

    def __unicode__(self):
        return '%s, %s' % (self.x, self.y)

    def __repr__(self):
        return '%s, %s' % (self.x, self.y)

    def __str__(self):
        return '%s, %s' % (self.x, self.y)

当我尝试通过ipdb评估实例时,我得到:

> /home/...
    151         p = Point(float(each[4]), float(each[3]))
--> 152         for i, _each in enumerate(headers):
    153             if not _each in headers_to_ignore:

ipdb> p
*** SyntaxError: SyntaxError('unexpected EOF while parsing', ('<string>', 0, 0, ''))

我希望有类似的东西:

123.0, 321.0

我错过了什么？
