how to update spyder on anaconda

问题

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?

To expand on juanpa.arrivillaga's comment:

If you want to update Spyder in the root environment, then conda update spyder works for me.

If you want to update Spyder for a virtual environment you have created (e.g., for a different version of Python), then conda update -n $ENV_NAME spyder where $ENV_NAME is your environment name.

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

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."

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

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

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:
