Description

What steps will reproduce the problem?

i don't know ,i just download the ananconda from website and install

Please post the output of

conda list

to better understand what's happening in your case. Thanks!

[ccordoba12]

@dalthviz, let's try to reproduce this error. Please update conda to its latest version (4.7.5) install the anaconda package in a new environment, then try to update Spyder with

conda install spyder=3.3.4

This seems to be a conflict between the latest anaconda package (which demands Spyder 3.3.3) and Spyder 3.3.4, which has a different requirement on spyder-kernels.

@ccordoba12 I tried but in the new environment the update is sucessful this is the list of package after the update of Spyder:

However, testing with my base/root environment the following error raises:

[ccordoba12]

This is interesting. @dalthviz, could you downgrade to conda 4.6 and try again? I think this could be a problem with the latest conda solver.

Also, could you reproduce this in a different Windows account by installing the latest Anaconda for that user and trying again?

Besides, please try this on Linux too to see if it's not a Windows only issue. Thanks!

[dalthviz]

@ccordoba12 when I tried to downgrade conda I needed to follow the instructions on this issue. After doing the downgrade I was able to do the update of Spyder:

I'm pending to check on Linux and with a different Windows account

[dalthviz]

Checking on Ubuntu/Linux (with the Python 2.7 install I have) after updating conda:

[dalthviz]

Checking with another Windows account, downloading and installing Anaconda from here:

• Doing conda list shows that the root/base env comes with conda 4.6.11
• After updrading to conda 4.7.5 the same error raises:
  

[ccordoba12]

@dalthviz, please try with Anaconda3 on Linux, instead of using version 2.

[dalthviz]

@ccordoba12 I tried an Anaconda3 install on Fedora 30 and the same error raises:

[ccordoba12]

Pinging @msarahan and @mingwandroid about this problem. Basically, if you have conda 4.7 and try to update Spyder in your base environment, you get the reported UnsatisfiableError in the screenshots posted by @dalthviz. @dalthviz also verified that this problem doesn't appear with conda 4.6.

Could you take a look at it? Thanks!

[msarahan]

Probably related to conda/conda#8844 please try to reenable the free channel and retry.

[ccordoba12]

Ok, thanks @msarahan for the quick response!

@dalthviz, please do that and try again.

[dalthviz]

@ccordoba12 on Windows same error raises but with more packages:

On Fedora 30 a different error raises:

@msarahan I set the free channel using .condarc with conda config --set, should I use something different to set the free channel?

[msarahan]

That particular missing package is really weird. It's most certainly present in our repodata. It could be a bug in conda with how it's trying to pin dependencies. I'll try to reproduce to see if I can learn anything, but nothing obvious stands out right now.

[msarahan]

This works fine for me on a totally vanilla python 3.7 env:

conda create -n py37env python=3.7
conda install -n py37env spyder=3.3.4

This is with stock conda - no free channel modification. Am I missing something? Are you trying to install into an existing env? Can you help me reproduce that initial env?

[dalthviz]

Yep, creating a new env and installing there Spyder works as well for me. The errors are raising when I try to use conda install spyder=3.3.4 in the base/root env after upgrading conda from 4.6.11 to 4.7.5.

The base env that I'm using is the one that came with the latest installer available (Anaconda 2019.03). Over this env I used conda install conda=4.7.5 and then I try conda install spyder=3.3.4

Just in case, these are the packages lists on Windows and Fedora in my case:

[ccordoba12]

@dalthviz, please update to conda 4.7.6 to see if that solves this problem.

[jkbhagatio]

which channel can conda 4.7.6 be found on?

[ccordoba12]

Defaults, but it seems it hasn't been released yet (I thought it was).

[dalthviz]

@ccordoba12 should I install conda from conda-canary?

[ccordoba12]

Sure, if you have time and that's not too complex.

We think we fixed that one in 4.7.7. It's on conda-canary if you want to try. The issue was a race condition caused by the repodata intake being parallelized. If the free channel content is loaded first, you get that error. If the main channel content is loaded first, you don't.

[dalthviz]

I tried with 4.7.7 but seems that it hangs out (I had to interrupt the process since I waited for at least 5 min but it didn't pass further than from 'Solving environment:'):

[dalthviz]

An update: after trying with conda 4.7.10 on Windows I was able to update spyder to version 3.3.4. Also to update from version 3.3.4 to version 3.3.6 I had to specify the spyder-kernels version:

[dalthviz]

@pengyunshan could you update conda to 4.7.10 and try updating Spyder again? Thanks :)

Probably for Spyder 3.3.6 you will need to run something like conda install spyder=3.3.6 spyder-kernels=0.5

It's WORD! I update the conda spyder,the history log return to normal! thx~

[ccordoba12]

Probably for Spyder 3.3.6 you will need to run something like conda install spyder=3.3.6 spyder-kernels=0.5

But it should work without the second requirement, i.e. without the need to explicitly specify an spyder-kernels version.

@msarahan, any thoughts about this?

[msarahan]

You updated the spyder-kernels requirement: https://github.com/AnacondaRecipes/spyder-feedstock/blame/master/recipe/meta.yaml#L48 but @dalthviz had at some point in the past explicitly specified spyder-kernels=0.4. Conda 4.7 tracks explicit requests much more that earlier versions. It uses the history to build up the specs, rather than using the state of the prefix to build up the specs. This is an optimization, but it also has the nice effect of allowing straightforward updates from earlier python packages that have shim packages, like enum34, to python versions that no longer need and indeed don't have those shim packages. With the new behavior, the shims fall away, because they were never explicitly requested, and they lose their connection to any explicit request. The message tries to communicate that, but it's probably a bit terse, especially if you aren't familiar with that solver behavior change.

The following specifications were found to be in conflict with a past explicit spec that is not an explicit spec in this operation

In other words, "you asked for this specific thing earlier. I can't fulfill your current request without breaking that past request. If you want to make this update, please tell me it's ok to change your past request by adding a new explicit spec to your command that will allow this change"

You can either put in new bounds, or you can neuter it by just passing the package name.

I had similar issue, and it was happening because I had jupyter nb running on my machine. I closed it and was able to update packages using conda.

[ccordoba12]

Closing because the solution is to run

conda update anaconda

then run

conda install spyder=3.3.6

or

conda install spyder=4.0.0
