Hi Carlos,

As I said in Google Spyder group, a Spyder update is so painful. I can't update to Spyder 4.2.3 nor 4.2.2. Then I uninstalled Anaconda, I installed it again and I wrote :

conda update anaconda

conda install spyder=4.2.3

but it didn't work. I got this error message :

(base) C:\Users\Jean-Louis>conda install spyder=4.2.3
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Thank you Carlos.

Have you tried:

conda install -c conda-forge spyder=4.2.3

Usually you should use the conda-forge channel as it is more up to
date. Have a look here (https://anaconda.org/search?q=spyder).

Kind regards.

Hi,

Please use our installers if you want a very stable Spyder:

If this helps anyone, I was able to upgrade to the latest spyder 4.2.3 with:

$ python3 -m venv spyder-env
$ source spyder-env/bin/activate
(spyder-env) $ pip install wheel

(spyder-env) $ pip install --upgrade spyder

Hi,

Carlos, I used your link to install the update. I opened the "Advanced installation / Details" but it didn't work.

Even if I don't understand English very well, I think I used the good instructions as I wrote them in my previous message.

Kiko, I used your instruction and it worked well.

Thank you guys for your help 🙂 .

Please give the link to your step by step instructions.

Thank you

Then :

Advanced installation

Important Notes

1. If you are new to Python or the Scientific Python ecosystem, we strongly recommend you to install and use Anaconda. It comes with Spyder and all its dependencies, along with the most important Python scientific libraries (i.e. Numpy, Pandas, Matplotlib, IPython, etc) in a single, easy to use environment.
2. We also support pip, but please be aware that pip installations are for advanced users with good knowledge of all Spyder dependencies. Because of that, all installation problems you encounter are expected to be solved by you.

Anaconda

You can easily install this version if you use Anaconda by closing Spyder and then running the following command in a system terminal (Anaconda Prompt on Windows, xterm on Linux or Terminal.app on macOS):

conda install spyder=4.2.3

Note: If you installed Anaconda for the first time, you need to run the following command first:

conda update anaconda

before running the command above.

So I tried with :

conda update anaconda

conda install spyder=4.2.3

[Carlos Córdoba]

Hi,

I clearly said that you should use our installers if you want a very stable and hassle-free update process. So I really don't understand why you keep insisting to use the instructions for Anaconda.

Now, why can't install Spyder 4.2.3 with Anaconda?

1. Because Anaconda takes some time to release new packages. That varies between two weeks and a month, and we don't have any control over it.
2. Even after the package is available, it's not certain that the update will be performed without problems (and we can't do anything about it either).

So, again, if you don't want to suffer with issues when updating Spyder anymore, please use our Windows or macOS installers, which are referenced in the "Simple installation" section of our release instructions.


Thanks,
Carlos

Hi Carlos,

Sorry Carlos but in the web link you gave to install Spyder, there are the instructions I used. Then it's a little confusing. And when I wanted to test Spyder, Spyder website gives the Anaconda link to install Spyder, there is no Spyder download in Spyder website.

In addition, when I tried a lot of solutions to install the new Spyder version, I had also executed "Spyder_64bit_full.exe" but when I executed a Python program, it didn't recognize Pywin32 while I have to work on Excel and Word files. Spyder seemed to be installed in another folder without the good links. Then I uninstalled Spyder.

Then can we use Spyder without Anaconda ? And have you a solution to use Spyder with Pywin32 without Anaconda ?

Thank you Carlos.
