However, I installed Sage on Windows 10 from the bin files without installing Cygwin at all. How should I update both Sage and the packages?
I favour an easy way that does not make me uninstall-reinstall.Thu, 20 Jun 2019 17:24:07 +0200https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/Comment by Iguananaut for <p>The <a href="http://doc.sagemath.org/pdf/en/installation/installation.pdf">Sage Installation Guide Release 8.7</a> seems to assume that one installs Sage in Windows using Cygwin, in particular regarding upgrading.

https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=47039#post-id-47039@vdelecroix's first comment is correct. The SageMath installer for Windows includes its own copy of cygwin built-in, including more-or-less exactly the dependencies it needs to run and nothing more. I'm not sure why you're specifically trying to "find Cygwin", but as @vdelecroix there is unfortunately not yet a specific "upgrade" functionality. You can have multiple versions installed side-by-side, and just uninstall the ones you're not using anymore.Tue, 02 Jul 2019 14:43:11 +0200https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=47039#post-id-47039Comment by Jesus Martinez Garcia for <p>The <a href="http://doc.sagemath.org/pdf/en/installation/installation.pdf">Sage Installation Guide Release 8.7</a> seems to assume that one installs Sage in Windows using Cygwin, in particular regarding upgrading.

https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46987#post-id-46987@vdelecroix I don't think that is correct. I downloaded bin files here http://www.mirrorservice.org/sites/www.sagemath.org/win/index.html and then simply ran the installation file. I do not have cygwin installed on my computer. If sagemath installs cygwin and runs over it, it does it in a completely transparent way. I cannot even find a cygwin folder in my computer.Mon, 24 Jun 2019 17:15:05 +0200https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46987#post-id-46987Comment by vdelecroix for <p>The <a href="http://doc.sagemath.org/pdf/en/installation/installation.pdf">Sage Installation Guide Release 8.7</a> seems to assume that one installs Sage in Windows using Cygwin, in particular regarding upgrading.

https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46988#post-id-46988I still believe that you have installed cygwin! You should check for the presence of `c:\program files\cygwin`.Mon, 24 Jun 2019 21:27:53 +0200https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46988#post-id-46988Comment by Jesus Martinez Garcia for <p>The <a href="http://doc.sagemath.org/pdf/en/installation/installation.pdf">Sage Installation Guide Release 8.7</a> seems to assume that one installs Sage in Windows using Cygwin, in particular regarding upgrading.

https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46989#post-id-46989@vdelecroix It is not there. I tell you, I have done a search for cygwin and there is not such directory in the whole disk.Tue, 25 Jun 2019 02:37:32 +0200https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46989#post-id-46989Comment by vdelecroix for <p>The <a href="http://doc.sagemath.org/pdf/en/installation/installation.pdf">Sage Installation Guide Release 8.7</a> seems to assume that one installs Sage in Windows using Cygwin, in particular regarding upgrading.

https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46981#post-id-46981What do you mean "from the bin file"? If you downloaded the installer from https://github.com/sagemath/sage-windows/releases then you did install SageMath on Cygwin. Concerning update on Windows, I don't think that there is anything easier for now than uninstall-reinstall.Sun, 23 Jun 2019 18:13:28 +0200https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=46981#post-id-46981Answer by Iguananaut for <p>The <a href="http://doc.sagemath.org/pdf/en/installation/installation.pdf">Sage Installation Guide Release 8.7</a> seems to assume that one installs Sage in Windows using Cygwin, in particular regarding upgrading.

https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?answer=49731#post-id-49731I forgot about this question, but just as a quick follow-up Jesus and I met last week at the University of Essex and I walked him through building Sage on Windows/Cygwin using the instructions at: https://trac.sagemath.org/wiki/Cygwin64Port
As we noted at the time, one bit of information currently missing from those instructions is to set:
```
export FFLAS_FFPACK_CONFIGURE=--disable-openmp
```
This is just to work around a slight defect in the build system that should get fixed at some point...Fri, 31 Jan 2020 18:25:24 +0100https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?answer=49731#post-id-49731Comment by shinster for <p>I forgot about this question, but just as a quick follow-up Jesus and I met last week at the University of Essex and I walked him through building Sage on Windows/Cygwin using the instructions at: <a href="https://trac.sagemath.org/wiki/Cygwin64Port">https://trac.sagemath.org/wiki/Cygwin...</a></p>

https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=49732#post-id-49732Hi, I'm not sure what you intended exactly by this answer but it appears to be misleading. Sage on Windows uses Cygwin. MinTTY is just a terminal emulator that is included in Cygwin, and is also the terminal emulator used by default when running Sage for Windows.Fri, 31 Jan 2020 18:27:10 +0100https://ask.sagemath.org/question/46958/updating-sage-in-windows-10/?comment=49732#post-id-49732
