## Installing the latest development version from github ## Installing the latest development version from github
If you are concerned about mucking with your installed packages, you might try using the new [virthualenv](http://hackage.haskell.org/package/virthualenv) tool to isolate a custom yesod build to a particular application. Currently there is a very annoying issue that aeson, a Yesod dependency requires deepseq < 1.2
A new version of aeson should be released fairly soon.
This means that before installing Yesod you should
~~~
cabal install deepseq-1.1.0.2
~~~
To ensure that cabal prefers this package you need to first start from a clean slate.
The easiest way to do that is to use [virthualenv](http://hackage.haskell.org/package/virthualenv), which will prevent any conflicts with presently installed packages by creating an isolated install environment.
~~~
cabal install virthualenv
mkdir yesodweb
cd yesodweb
virthualenv --name=yesod
~~~
Yesod is broken up into 4 separate repos and built upon many smaller packages. Yesod is broken up into 4 separate repos and built upon many smaller packages.
