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 :

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
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.

(Spyder maintainer here) Other users have reported that you need to run

conda update anaconda

and then

conda install spyder=4

to successfully update to version 4.

  • I had the same issue. I re-installed conda and was able to update Spyder to v4.0.0. My problem is that as soon as Spyder starts up in an environment with Python 2.7 it crashes immediately; however, it works fine with Python 3.x – mfaieghi Dec 11 '19 at 15:02

    Some how this process kept installing 3.6 even after deleting manyally the spyder executable. From anaconda navigator I couldn't get any version above 3.6. THis is what worked: 1) from the navigator, uninstall spyder 2) install spyder it magically pulled 4.0.1 – andrea m. Feb 14 '20 at 20:42

    Also did it for me in the Anaconda Prompt **with administrator privileges**. Awesome! – AfterMath Feb 15 '20 at 18:47
  • @andy removing spyder from the navigator worked. Then the suggested spyder version was 4.0.1, weird magic. – Svenno Nito Feb 21 '20 at 22:12
  • @CarlosCordoba I can't install Spyder 4.1.2 from the anaconda navigator (says it's available). It just hangs for every saying that it's "upgrading". Can you comment on this? – ThatsRightJack May 03 '20 at 08:41
  • You can't update from navigator. You need to use the Anaconda Prompt and run the commands I wrote in my answer above. – Carlos Cordoba May 03 '20 at 14:25

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

An additional note here for those trying to upgrade to Spyder 4 and use conda environments in Windows 10. I was wanting to use Spyder 4 but also getting the error inside Spyder saying that it could not find the spyder-kernels. This happened regardless of (1) whether or not I installed Spyder inside a new environment or the base environment, and (2) even if I subsequently installed spyder-kernels through conda.

I tried to follow the advice given above and already had Anaconda installed (via the windows installer) but when I tried:

conda update anaconda

It could not find Anaconda inside the base environment. So I installed Anaconda using conda anyway (even though this seems kind of recursive to me):

conda install anaconda

After that I was able to update Anaconda by:

conda update anaconda

Once I did that I was able to run Spyder 4 from the base environment (already installed) and I was getting a working Ipython kernel.

So then I could open Spyder from the base environment and using the Spyder menu, Tools -> Preferences -> Python Interpreter, I can set the conda environment I want to be in, eg, C:\Users<User Name>\Anaconda3\envs\myenv\python.exe

Then, to allow Spyder to create a Ipython Kernel inside the conda environment that I would like to work in, I have to install spyder-kernels into this environment, so, I started up a new Anaconda prompt, and:

conda activate myenv

conda install spyder-kernels

Finally, back in Spyder, I restarted my kernel (Ctrl + .). This gave me a functioning Ipython kernel , and looking at the status bar at the bottom of the Spyder window, I could see that I was in the myenv environment.

So now I can use the Spyder IDE (starting it from the base environment) but be able to work inside previously created conda environments. It also avoids having to install the full Spyder into each environment I create (but does mean having to install spyder-kernels into each environment).

  • Tried to install spyder-kernels in my env but there are a lot of conflicts in the packages. Do you know how to proceed? In my env, Sypder does not install through conda install or in the Navigator itself. Thanks, @land-ahoy. – BallpenMan May 09 '20 at 12:40

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)

  • I followed your recommandation, but it did not work, how do you open Spyder ? – Basile Dec 12 '19 at 16:10
  • Do you have the `conda-forge` channel added? If not, it may help: `conda config --env --add channels conda-forge`; then try to update again. I open Spyder simply from Windows' Start Menu – BottleNick Dec 12 '19 at 20:22
  • I got this new issue : `ERROR conda.core.link:_execute(568): An error occurred while installing package 'defaults::autopep8-1.4.4-py_0'. CondaError: Cannot link a source that does not exist. C:\Users\brichard\AppData\Local\Continuum\anaconda3\Scripts\conda.exe` – Basile Dec 13 '19 at 09:43

I solved this by uninstalling Spyder then installing by the specific version:

conda uninstall spyder

conda install spyder=4.1.5

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.

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

then I did the below, it worked!
