Nikola in a virtual env and txt2tags

[Mike Ray]

Hello,

I am trying to use Nikola in a virtual environment.

I have got the environment created correctly and everything is wrking
except, some of my pages are written with txt2tags.

I have installed txt2tags from github in the venv. It is correctly in:

/home/mike/virtualenv/Envs/raspberryvi/bin

And when I run txt2tags outside of Nikola it is the correct one which is
running because I have put a print statement in the top of the script
and the shebang line has the right path in it.

But when Nikola tries to render a txt2tags page it claims txt2tags is
not installed.

It is as if Nikola is not "seeing" the correct path.

When, in the venv I type:

echo $PATH

The first entry is a path to the bin directory of the virtual environment.

Any ideas?

Mike

We use this Python code:

from txt2tags import exec_command_line

Can you run this from a Python interpreter that lives in the same
environment as Nikola? (try `nikola console`) Also why txt2tags? Why
not use something more standard like Markdown?

Hello Chris,

I like the table syntax of txt2tags. One of the things which is missing
from markdown. My sites have a mix of markdown and txt2tags. I only use
txt2tags for those pages which have tables. I may convert them to
kramdown since I wrote the kramdown plugin.

Here is the result of the code:

Traceback (most recent call last):
File "<stdin>", line 2, in <module>
from txt2tags import exec_command_line
ImportError: No module named txt2tags

And here is the text of txt2tags, which is in
/home/mike/virtualenv/Envs/raspberryvi/bin :

#!/home/mike/virtualenv/Envs/raspberryvi/bin/python
# EASY-INSTALL-SCRIPT: 'txt2tags==2.6','txt2tags'
__requires__ = 'txt2tags==2.6'
__import__('pkg_resources').run_script('txt2tags==2.6', 'txt2tags')


When I put a print in the line below the shebang and run it in the venv
it works.

reStructuredText supports an even simpler syntax:

Nikola is probably in a different environment, try

$ which nikola

to find out what it is, and install txt2tags there. Or just install
user-wide (pip install --user)

[Mike Ray]

It's in the right env and txt2tags is the right version.

pip install txt2tags

Says requirement already satisfied.

In `nikola console`, run:

import nikola, sys
print(nikola.__file__)
print(sys.path)

and show me the results.
