Console throws error about wurlitzer on fresh install #8668

ptoche · 2019-01-29T18:07:30Z

Can't get started anymore. This is the state of my Spyder console at startup. I have fresh-installed Python 3 from miniconda and Spyder 3. I'm on MacOS (latest). Any suggestions? Thanks!

Thanks for reporting. We'll fix this in our next release (3.3.3) to be ready in a couple of days.

ccordoba12 · 2019-02-02T10:19:19Z

We have tests for this feature and they didn't detect your problem. So we relay on users to let us know about this kind of problems.

namus · 2019-02-14T09:09:44Z

I am using Spyder 3.3.3 installed through conda along with Python 3 in Mac OS X 10.14.3. On opening Spyder, I get the following error messages in the console. Same error message appears every time a script is run, or interactive mode is used. The scripts work fine, but the error message is rather annoying!

I have the same with Spyder 4.

same issues on Mac Catalina 10.15.2

It just suddenly came back. Latest MacOS/Python/Spyder.

Edit: Came and went. 👍

vibhormehta · 2020-02-12T21:17:24Z

I am facing the same problem with my mac. This stopped showing up. But this error is back now.

Edit: This was fixed (temporarily?) by running

conda update anaconda

linmiepii · 2020-02-16T01:11:10Z

I met the same problem with fresh install of Spyder 4

Do you mean?

conda update conda
conda update -all

Seems to be solved with:

conda install -c conda-forge wurlitzer

CommonClimate · 2020-04-28T18:08:54Z

Yup, still an issue for me despite installing the latest wurlitzer (from conda-forge, as above).
Configuration:

Mac OS 10.15.4
Spyder 4.1.2
Python 3.7.7 (installed through miniconda)
Wurlitzer 2.0.0

Any solution welcome

yotamcons · 2020-05-20T12:38:52Z

I have the same issue..

Mac OS 10.15.4
Spyder 3.3.6
Python 3.6.10
Wurlitzer 2.0.0

A strange phenomena that might make solving this much harder: After I close Spyder and reopen everything works well - but if I log out and log back in it comes back

federicoVisi · 2021-01-31T10:33:46Z

I had the same issue on MacOS and figured out it occurs just when launching Spyder from Terminal, no issue if Spyder is launched from Anaconda Navigator.
