Pylint Not Working

[Robert Love]

I have Spyder installed from the latest Anaconda updates this week.   I have pylint installed using 'pip install pylint'.   I can use pylint from the command line to analyze my program.   However, from Spyder, I get a string of errors when I choose the Static code analysis tab and the Analyze button I get a long string of errors shown below.

First, is the the correct place to ask or is this an anaconda issue?

Second, I see the Spyder documentation says in the Editor section that pylint can be used but doesn't say much about how or installation.   What is the proper way to install pylint for use in spyder?

Traceback (most recent call last):

I don't understand what this is telling me.

First under Help --> Optional dependencies see what it shows for pylint.

Second I would think that 'pip install pylint' would install in the
system Python not Anaconda. Should you not do 'conda install or update
pylint'?

Third what OS and version and Python version are you using?

It says pylint  1.4.2 (OK)  Static code analysis

 

Second I would think that 'pip install pylint' would install in the
system Python not Anaconda. Should you not do 'conda install or update
pylint'?

OK, I've performed the install that way.   Same results.


 

Third what OS and version and Python version are you using?

Not sure it matters.   I get the same failure on both my Mac (10.10.4) and my Mint 19 Linux box.   Both have the same recent anaconda suite with Python 2.7.
BTW, on the Mint box pylint is version 1.44

So Spyder thinks pylint is of correct version, that's a start.

Just verifying we are talking apples to apples.

It provides context and also helps narrow down whether it is an OS
specific bug for now and for those folks who wander across this thread
in the future.

So onward.

What version of Spyder are you using?
I am on 2.3.3 on openSuse 13.1 and the static analysis works.

What are you trying analyze and where is it?


The error you got:

self.stats['by_module'][self.current_name][msg_cat] += 1

KeyError: None

would seem to indicate information is missing, in that one of the above
keys is None.

Uh, we can close this out and mark it user ignorance.  I have one file in the editor, the only file I'm working on.   I assumed, that Static Analysis would automatically apply to the only  file I was working on.   No, I had to type the file name in the field at the top of the analysis pane, then it worked like a charm.

FYI, there is a file selector(open folder) just to the right of the file
field.

Well, I would not call this user ignorance.

The current user interface is really confusing (even though I use it a lot since any years).

It would be nice, if the plugin would always run pylint on the currently open file.
