Error When Running Flake8

[jp-walker]

Attempting to run flake8 on ../continuous-integration/Fixme.py with both commands

$ flake8 Fixme.py

and

$ flake8

which return this block of text:

I scoured google, restarted my computer, and restarted the lambda server multiple times and still couldn't figure out what was happening. Thanks!

@jp-walker

I had the same issue and was able to solve it with

$ flake8 -j1 Fixme.py

Shoutout to @finnless for the fix!

@jp-walker and @jbecker7: These are both overall a great question/answer exchange. But in the future, anytime you are including a prompt like $ in a code snippet, that's a sign that you want the triple backticks instead of the single backticks. So, for example,

$ flak8 -j1 Fixme.py

would be better as

$ flake -j1 Fixme.py

[jp-walker]

@mikeizbicki I just double checked and I used the triple backticks for that section. Is there something else I can change? Thanks!

[mikeizbicki]

@jp-walker Both of your commands that start with a $ are still using inline code instead of code blocks. Only the error message is in a code block.
