There was a problem hiding this comment.
If we set the version of TextFSM, then we should also remove the try/except block here:
ntc-templates/lib/ntc_templates/parse.py
Lines 4 to 7 in fb64024

You want me to make that edit in this PR also (the parse.py multiple import edit--for old/new textfsm)? |
|
That would be great. Thanks |

Sounds good. Will update. |

Thanks @ktbyers |

There was a long-standing issue in TextFSM which caused textfsm to break on Windows. This was due to the TextFSM library importing the "fcntl" library (inside TextFSM's terminal.py module).
ntc-templates had a workaround for this problem where they installed a completely different
terminallibrary.This worked in textfsm 0.4.1 as textfsm_0_4_1 would put all of its Python files directly into site-packages (literally ./site-packages/terminal.py). Consequently, the install of the other
terminalmodule would overwrite theterminal.pythat came installed with textfsm.With this fix here:
https://github.com/google/textfsm/blob/v1.1.1/textfsm/terminal.py#L25-L29
And with the fact that textfsm is now installed as a proper package in site-packages (in other words
site-packages/textfsm/and then the package files inside that directory).The installation of the other
terminalpackage should now be useless.The relevance to me is that I am interested in making ntc-templates a direct Netmiko dependency, but I don't really like installing this separate terminal.py file (https://github.com/lepture/terminal) as that library is unmaintained (last commit in 2013)
Additionally, I have had interoperability issues with the ntc-templates fix to this problem in the paste. And now that it is obsolete, it would be good to get rid of it.
There is no code that is actually by in terminal.py by ntc-templates or Netmiko (in either the old or the new solution). The problem is entirely an import issue.
