Was able to install by code below.

$ git clone git://github.com/BurntSushi/erd
$ cd erd
$ stack init
$ stack build --system-ghc

[qizwiz]

Thanks for this!
While I think your method is preferable, I was also able to get it to install by changing the base from 4.7 to 4.9 in the cabal file.

[chreble]

Better use

cabal install --allow-newer erd

[carld]

Haskell newbie here, started out with brew cask install haskell-platform

% cabal install --allow-newer erd

[carld]

For posterity... I installed erd after running --force-reinstalls of parsec etc

[combinatorist]

I spent 3 hours trying to install this package. As a first time haskell user, I tried everything with no clue what I was doing until I saw this comment: #24 (comment) by @chreble

Thanks @chreble!

I just made a PR (#27) to "fix" the documentation. I have no idea how this works, but would love to make it easier for first time users.

[kyr0]

Yes, please add it to the docs; it's such an easy change... I was looking into it for a few minutes too.

My system was clean, first time using an haskell software, not exactly newbie friendly. I ran brew install ghc cabal install and cabal install erd

[nwokeo]

I had the same problem, seems to be due to this issue.

I was able to resolve by installing haskell-platform via cask: brew cask install haskell-platform then installing erd: cabal install --allow-newer erd

That fixed it for me, thanks.

I don't know how this is working for people. I've tried on OSX and Docker and keep getting the following output:

[qizwiz]

@rclayton-the-terrible I just tried it myself and got your same errors. I noticed all the errors were the same and from the same package.

From that, I tried installing graphviz by itself.

$ cabal install graphviz

That worked. And then I was able to do:

$ cabal install --allow-newer erd

So give that a shot.

[rclayton-the-terrible]

@qizwiz hey that worked! Thank you so much.

I don't know a thing about Haskell or it's toolchain, but I noticed installing via cabal doesn't create an executable on the $PATH, so I've been running everything with cabal run erd -- ... . Is this the right approach? Or am I missing something?

[qizwiz]

@rclayton-the-terrible
I have a mac. It looks like you have linux.

The relevant lines in my ~/.cabal/config file looks like this

-- === Built executables will be installed in:
--     ~/Library/Haskell/bin
--
-- You may wish to place this on your PATH by adding the following
-- line to your ~/.bash_profile:
--     export PATH="$HOME/Library/Haskell/bin:$PATH"

If this file exists, perhaps you'll find the same hint there for you (it'll almost certainly be different).
The documentation can be found here: 2.1. Configuration

[rclayton-the-terrible]

@qizwiz I tried both macOS and Linux (as a Docker container FROM haskell. Same outcome for both. The fix was to install Graphviz via cabal and not some other mechanism (like brew).

[qizwiz]

@rclayton-the-terrible I was addressing the second part of your question. Seemed like you were having problems with the binpath for packages you installed with cabal
