Spyder can't open a console because of problems with Beautiful Soup

[ilkerhk]

Description of your problem

Not sure if this is Conda or Spyder issue, but after the recent update of conda I can't open new ipython console.

What steps will reproduce the problem?

1. Install latest conda with : conda update --all
2. Observe that it updates to ipython 5.0
3. Open Spyder and create new ipython console

What is the expected output? What do you see instead?

Please provide any additional information below
The problem is with the new ipython version 5.0. Downgrading ipython back to 4.2 solved my issue.

I also have this issue, but now Spyder will not even load. the loading pop-up screen with the logo comes up for about 100ms, not enough time to read the error message. When I run spyder.exe, I get this:

Spyder version: 2.3.9
IPython version: 5.0.0

It works fine on my laptop, the only difference seems to be that my laptop runs Python 2.7.11.

It looks like a conda issue, no @ccordoba12 ?

[MadDenker]

I cannot pull up an IPython console, either.

Traceback (most recent call last):

[ccordoba12]

Yes, it seems you have a broken installation now. Please reinstall Anaconda and report again.

[MadDenker]

I was able to get IPython to load again using conda install -f IPython found here: http://conda.pydata.org/docs/troubleshooting.html

[MadDenker]

So, I was unable to install or update this bs4 package. It appears to be Beautiful Soup. The init.py file states lxml and/or html5lib be installed. After installing html5lib, Spyder loads up.

This appears to be a dependency issue. The new version of spyder should note this dependency on install!

[ccordoba12]

We don't depend on beautifulsoup or html5lib, so this is really a dependencies problem with Anaconda.

I'm glad you were able to find and solve your problem ;-)

[MadDenker]

@ccordoba12 I wouldn't be so quick to close this. It look like @ilkerhk still has an issue.

[MadDenker]

I also demonstrated that the spyder package imports bs4. So it appears that spyder does use Beautiful Soup.

File "C:\Anaconda\lib\site-packages\spyderlib\widgets\dicteditorutils.py", lin
e 78, in
import bs4

[ccordoba12]

It's true we import bs4 but it's a conditional import, we don't depend directly on it.

So although this is clearly an installation issue, we can add a bit of code to address it ;-)

[ilkerhk]

I tried with and without beautifulsoup and html5lib, but didn't see any effect. I still can't run with a different error (see below). But downgrading back to iPython 4.2.0 + Spyder2 works for me. I am OK with those.

Thanks all for the replies.
best,

P.S. I've just tried fresh conda environment. After the install everything works fine (Spyder2 and iPython 4.2.0 ). If I upgrade to Spyder 3, I got the below error. I upgrade to iPython 5.0 still got below error.

An error ocurred while starting the kernel
Either:
Your IPython frontend and kernel versions are incompatible or
You don't have IPython installed in your external interpreter.
In any case, we're sorry but we can't create a console for you.

[ilkerhk]

I realized I have other issue(s) with the setup. I installed all fresh but still getting error. So please ignore the error I mentioned in the last comment.
I will open a new issue.

[jitseniesen]

The error in the first comment (which is about IPython 5 and Pygments and has nothing to do with beautifulsoup) has also been reported in issue #3309.

[MadDenker]

@ilkerhk try to force install pygments

[ilkerhk]

Thanks @MadDenker ,
I tried a clean install and followed both your suggestions and working fine now with iPython 5.0...
