问题
I am under Windows 10, 64 bits.
I tried several time to update Spyder 4.0.0 with both the Anaconda Prompt and the Anaconda Navigator. It failed. I uninstalled Anaconda and reinstalled it.
Then I ran the Anaconda Prompt as an Administrator and executed :
conda update spyder
The version of Spyder was 3.3.6. I tried this command :
conda install spyder=4.0.0
The prompt returned :

Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

When launching the Anaconda Navigator, the Spyder version was still on 3.3.6.
What am I missing to benefit the last version of Spyder ?
EDIT 1:
When I try to use the Anaconda Navigator, it says :
spyder 4.0.0 cannot be installed on this environment
And it proposes other environments to install but I want Spyder to be updated, not installed somewhere else.
EDIT 2: I successfuly change conda to 4.6, but I get these two errors :
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\brichard\\AppData\\Local\\Continuum\\anaconda3\\Menu\\spyder_shortcut.jsodone
and :
CondaError: Cannot link a source that does not exist. C:\Users\brichard\AppData\Local\Continuum\anaconda3\Scripts\conda.exe
Running `conda clean --packages` may resolve your problem.
The conda clean --packages command does not help since the same errors are raised after it is executed.
回答1:
(Spyder maintainer here) Other users have reported that you need to run
conda update anaconda
and then
conda update spyder
to successfully update to version 4.
Hope that helps.
回答2:
I also couldn't update Spyder to v4.0.0 on Win x64; but I found a solution.
A word about my setup: I use Miniconda and a conda environment with conda-forge as the top channel & the setting channel_priority: strict (a recommendation according to conda-forge). This causes conda to only consider packages from the conda-forge channel.
I disabled the strict channel priority for my active environment (which may be undesired in the future with conda v5.0+ [conda-forge]):
conda config --env --set channel_priority disabled
Now finally, I was able to update Spyder to v4.0.0:
conda update spyder
It appeared that conda needed the following packages (it took it from the defaults/anaconda channel):
blas-1.0, jupyter_client-5.3.4, pluggy-0.13.1, python-3.7.5, scipy-1.3.2.
jedi was downgraded (0.15.1-py37_0 --> 0.14.1-py37_0).
FYI: I also considered the other answers of:
- Carlos Cordoba - Problem: I have Miniconda, and do not want all the other packages associated with
anaconda. - pyXelr - I tried downgrading of
conda- didn't solve the problem.
Btw: creating a new clean environment with only Spyder v4.0.0 (and its dependencies) also only works with the strict channel priority disabled (when using conda-forge), that is, this doesn't work:
conda create -n spyder -c conda-forge --strict-channel-priority spyder=4.0.0
It also won't work if you execute the following from an environment with strict channel_priority:
conda create -n spyder -c conda-forge spyder=4.0.0
(you need to disable the channel_priority first)
回答3:
I managed to solve this issue, which probably occurred by keeping too many packages in the same root environment. Firstly, try downgrading conda, as it was suggested in the recent issue on the conda repository:
conda install -n root conda=4.6
Afterwards, give Spyder one more chance:
conda install spyder=4.0.0
If that did not work, I believe you can solve the problem as I did - through creating a new environment (for example using Anaconda Navigator) and installing Spyder 4.0.0 directly from there.
回答4:
I had freshly installed Anaconda on my PC. So doing just the following in Anaconda command prompt worked for me. Spyder, along with a lot of others, was updated to 4.0.0.
conda update anaconda
回答5:
I used the following:
conda update anaconda
and then
conda update spyder
conda install spyder=4.0.1
to successfully update to version 4.0.1
