[python] how to update spyder on anaconda

I have Anaconda installed (Python 2.7.11 |Anaconda custom (64-bit)| (default, Feb 16 2016, 09:58:36) [MSC v.1500 64 bit (AMD64)] on win32) and I am using Spyder 2.3.8

Would like to update Spyder to the latest version, so I went through the commands:

conda update conda
conda update anaconda
conda update spyder

They all ran without errors, but the spyder version didn't change - this is command I'm using to launch:

C:\Anaconda2\pythonw.exe C:\Anaconda2\cwp.py C:\Anaconda2 "C:/Anaconda2/pythonw.exe" "C:/Anaconda2/Scripts/spyder-script.py" --new-instance

Am I missing something?

In iOS,

• Open Anaconda Navigator
• Launch Spyder
• Click on the tab "Consoles" (menu bar)
• Then, "New Console"
• Finally, in the console window, type conda update spyder

Your computer is going to start downloading and installing the new version. After finishing, just restart Spyder and that's it.

You can easily install update 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= Your desire version

(For example, Version is 3.1)

conda install spyder=3.1

Or you can use pip with this command in a system terminal (cmd.exe on Windows, xterm on Linux or Terminal.app on macOS):

pip install --pre -U spyder

Note: Do not use this command if you are using Anaconda because it could break your installation.

Go to Anaconda Naviagator, find spyder,click settings in the top right corner of the spyder app.click update tab

Simply select 'Update Application' after clicking on the settings symbol(top right corner) for Spyder in the Anaconda Navigator console. In my case I just updated it so it's in disabled state.

make sure you in your base directory.
then conda install spyder will work.
Do it like this: conda install spyder=new_version_number.
new_version_number should be in digits.

One way to avoid errors during installing or updating packages is to run the Anaconda prompt as Administrator. Hope it helps!

I see that you used pip to update. This is strongly discouraged (at least in Spyder 3). The Spyder update notices I receive have always included the following:

"IMPORTANT NOTE: It seems that you are using Spyder with Anaconda/Minconda. Please don't use pip to update it as that will probably break your installation. Instead please wait until new conda packages are available and use conda to perform the update."

This worked for me: conda install --force-reinstall pyqt qt
Based on this

It's very easy just in 2 click

1. Open Anaconda Navigator
2. Go to Spyder icon
3. Click on settings logo top-right coner of spider box
4. Click update application

That it Happy coding

Use this conda install spyder=4.0.0 This will not mess up your anaconda dependencies. https://github.com/spyder-ide/spyder/releases

Using pip directly:

WARNING: This will break your Anaconda Installation as described by Spyder maintainer in the comments below; you can try this solution only if the solution mentioned above that use Conda do not work

pip install --upgrade spyder

You might get an error once launching the new Spyder "nbconvert >= 4.0: None (NOK)", which will require you to resinstall configparser:

conda uninstall configparser

conda install configparser

You should now have a fresh and up to date installation of Spyder.
