I installed the latest version of Cygwin with a number of packages. I soon realised that I need more packages (such as wget, etc) and I couldn't find a way to install the new packages without running the set up again and reinstall everything from scratch.

What I'm looking for is the equivalent of apt-get on Cygwin (if such a thing exists).

There is no package management in Cygwin outside of the setup program. The setup only applies updates to your current installation, it does not overwrite packages that what you already have (unless you have explicitly said so).

So rerun the setup program to install new packages.

There is a package called apt-cyg that may be what you are looking for. It appears to be based upon apt-get.

apt-cyg is a command-line installer for Cygwin which cooperates with Cygwin Setup and uses the same repository. The syntax is similar to apt-get.

An example command would be

$ apt-cyg install yourPackage

To install it you need wget, tar, gawk, and bzip2. You can download all these packages from the Cygwin packages list.

how do you install apt-cyg once you have downloaded wget, tar, gawk, and bzip2? thx –  Adrien Be Dec 11 '13 at 10:22

This should be preinstalled with cygwin. its so amazing –  Sameer Alibhai Aug 9 '14 at 19:25

Re-run the setup program again. This is how you update Cygwin as well.

thx, for those in doubt: it does not reinstall everything, it simply install the new packages that you select –  Adrien Be Dec 11 '13 at 10:40

I was stuck with the same issue while trying to use curl on Windows and just got it resolved. Posting it here, now cause it might help someone.

The best way is to just use cygwin's setup.exe and select additional packages that you need. Go here: http://www.cygwin.com/install.html

"When installing packages for the first time, setup*.exe does not install every package. Only the minimal base packages from the Cygwin distribution are installed by default. Clicking on categories and packages in the setup*.exe package installation screen will provide you with the ability to control what is installed or updated."
