Question

我最近尝试使用paramiko运行一段代码，代码只是构建一个基本的ssh端口，代码可以在其他机器上使用。但是，当我安装paramiko并在我自己的机器上运行代码时，它无法正常工作。我仔细检查了代码，以确保它是相同的。然后我在编译时检查了错误，它说：

post "/checkphone" => "phones#checkphone"
  post "/checksim" => "phones#checksim"

  resources :phones, path: '4g-promo'

我在网上寻找答案，它说我可能遇到的问题是我没有加密1.4.1软件包。因此，我使用pip来安装软件包，由于某种原因，我收到了与运行程序相同的错误。

    import paramiko
  File "/Library/Python/2.7/site-packages/paramiko/__init__.py", line 30, in <module>
    from paramiko.transport import SecurityOptions, Transport
  File "/Library/Python/2.7/site-packages/paramiko/transport.py", line 33, in <module>
    from cryptography.hazmat.backends import default_backend
  File "/Library/Python/2.7/site-packages/cryptography/hazmat/backends/__init__.py", line 7, in <module>
    import pkg_resources
  File "/Library/Python/2.7/site-packages/pkg_resources/__init__.py", line 72, in <module>
    import packaging.requirements
  File "/Library/Python/2.7/site-packages/packaging/requirements.py", line 59, in <module>
    MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")
  TypeError: __call__() takes exactly 2 arguments (1 given)

所以有人都知道我的机器会发生什么事吗？在安装加密之前，我还需要安装其他任何软件包吗？

我目前正在使用mac OS Y Yosemite，我的pip已升级。

这是原始代码：

希望这会有所帮助！

关于版本问题，我只是尝试使用pip来安装pycrypto（版本为2.6.1），同样的错误也会引发。

感谢您提前给予的大力帮助和耐心，彼得

嘿，我遇到了同样的问题。我尝试了以下说明，它的工作原理！（来自https://bugs.centos.org/view.php?id=12722&history=1的ptmcg）

包装模块的requirements.py中的这一行：

MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")

使用pyparsing 2.0.2中引入的功能，特别是使用＆＃34; expr（）＆＃34;复制表达式，在这种情况下＆＃34; MARKER_EXPR（）＆＃34;。升级到pyparsing 2.1.10（最新版本）是建议的操作过程，但也可以通过将requirements.py中的代码更改为：

来解决此问题。

MARKER_EXPR = originalTextFor(MARKER_EXPR)("marker")

（在这一行中，实际上不需要复制MARKER_EXPR。）
