SSHLibrary fails to import

[Rob Bovill]

The ongoing issues with the Robotframework-SSHLibrary on MacOS X continue.  I originally posted a bug to the GitHub repo, https://github.com/robotframework/SSHLibrary/issues/147, but no movement has occurred.

Yesterday, I upgraded my Mac to High Sierra (10.13.1), in the hopes the OS update would fix the compatibility issue.  After the OS upgrade finished, I updated Robot-Framework and SSHLibrary to their latest versions, namely

      /Library/Python/2.7/site-packages/robotframework-3.0.2-py2.7.egg-info

      /Library/Python/2.7/site-packages/robotframework_sshlibrary-2.1.3-py2.7.egg-info

The SSHLibrary installation instructions, https://code.google.com/archive/p/robotframework-sshlibrary/wikis/InstallationInstructions.wiki, include a step to verify the installation:

    > python -c "import SSHLibrary"




When I then tried this, I got the following error:

Traceback (most recent call last):

  File "<string>", line 1, in <module>

  File "/Library/Python/2.7/site-packages/SSHLibrary/__init__.py", line 15, in <module>

    from .library import SSHLibrary

  File "/Library/Python/2.7/site-packages/SSHLibrary/library.py", line 22, in <module>

    from .client import SSHClient

  File "/Library/Python/2.7/site-packages/SSHLibrary/client.py", line 20, in <module>

    from pythonclient import PythonSSHClient as SSHClient

  File "/Library/Python/2.7/site-packages/SSHLibrary/pythonclient.py", line 21, in <module>

    'Importing Paramiko library failed. '

ImportError: Importing Paramiko library failed. Make sure you have Paramiko installed.

I definitely have Paramiko installed,

      /Library/Python/2.7/site-packages/paramiko

      /Library/Python/2.7/site-packages/paramiko-2.4.0.dist-info,

so I tried

      > python -c "import paramiko"

and got this error:

Traceback (most recent call last):

  File "<string>", line 1, in <module>

  File "/Library/Python/2.7/site-packages/paramiko/__init__.py", line 22, in <module>

    from paramiko.transport import SecurityOptions, Transport

    from paramiko.ed25519key import Ed25519Key

  File "/Library/Python/2.7/site-packages/nacl/signing.py", line 19, in <module>

    import nacl.bindings

  File "/Library/Python/2.7/site-packages/nacl/bindings/__init__.py", line 17, in <module>

    from nacl.bindings.crypto_box import (

  File "/Library/Python/2.7/site-packages/nacl/bindings/crypto_box.py", line 18, in <module>

    from nacl._sodium import ffi, lib

ImportError: dlopen(/Library/Python/2.7/site-packages/nacl/_sodium.so, 2): Symbol not found: _crypto_box

  Referenced from: /Library/Python/2.7/site-packages/nacl/_sodium.so

  Expected in: flat namespace

 in /Library/Python/2.7/site-packages/nacl/_sodium.so

Suffice it to say, I would appreciate any help or insight.  Until I get this fixed, I cannot run my automated tests.

NOTE: I am cross-listing this post in the original bug mentioned above.

After upgrading to High Sierra, did you also check for updates and update your XCode?

      I found the issue with Paramiko was already reported to the developers.  Here's the link, https://github.com/paramiko/paramiko/issues/1020.  I don't want to downgrade paramiko, as that would force downgrades to other libraries.  Has anyone else found a solution or workaround?  The problem seems to only exist on MacOS Sierra and above.
