无法安装 conda spyder 包构建

Question

I want to install a specific build of spyder on conda - version 3.3.0 with py36_a build.

# Name                  Version           Build  Channel                             
spyder                    3.3.0          py27_0  pkgs/main           
spyder                    3.3.0          py36_0  pkgs/main           
spyder                    3.3.0          py37_0  pkgs/main           
spyder                    3.3.1          py27_1  pkgs/main           
spyder                    3.3.1          py35_1  pkgs/main           
spyder                    3.3.1          py36_1  pkgs/main           
spyder                    3.3.1          py37_1  pkgs/main 

But when I do, I get an error that the package has not been found.

$conda install spyder=3.3.0=py36_1
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

I also tried conda install -c pkgs/main spyder=3.3.0=py36_1 but it gave me the same error. What's wrong here?

Answer 1

This is not really recommended, and updating one or more dependencies to a version not tested together in the anaconda meta package is the likely reason for this problem in the first place.

However, the fact that updating,.. something...is requiring Spyder>=3.3.0 is worrisome, and seems to match what was reported on another thread. Could you please run

conda install spyder=3.3.0 

and post your full output here, We need to know what's causing this issue.

And also dont't try to doing conda update --all .

Instead, you need to do below

conda remove spyder-kernels
conda install spyder-kernel==0.*
conda update spyder

My suggestion is simply to update the packages that you an update for:

conda update spyder, conda update pandas , etc.
