cabal keeps saying packages not installed though they are indeed there

[n6151h]

During build-prod I see the following output:

nicks@numidea:~/prova/degust$ sudo bash build.sh prod-server
Building 'prod-server'
Combining css and minifying...
Compiling CoffeeScript and bundling all js...

Building backend
cabal: Run the 'configure' command first.

I run the configure command and get:

nicks@numidea:~/prova/degust$ sudo cabal --global configure
Resolving dependencies...
Configuring degust-0.14...
cabal: At least the following dependencies are missing:
bytestring ==0.9.*,
cgi ==3001.1.*,
json ==0.7.*,
lens >=3.9 && <4,
random ==1.0.*,
text >=0.11.2 && <1

I have already installed all of these, but, didn't use the --global switch, so tried again (just with bytestring package to save a bit of time.):

nicks@numidea:~/prova/degust$ sudo cabal --global install bytestring
Resolving dependencies...

and re-run cabal configure:

nicks@numidea:~/prova/degust$ sudo cabal --global configure
Resolving dependencies...
Configuring degust-0.14...
cabal: At least the following dependencies are missing:
bytestring ==0.9.*,   <<<<<<<<<<<<<<<<  STILL NOT INSTALLED?!?!
cgi ==3001.1.*,
json ==0.7.*,
lens >=3.9 && <4,
random ==1.0.*,
text >=0.11.2 && <1

Is this a known or simple issue, requiring specific version of cabal, perhaps? If not, I'll dig some more but wanted to ask before I invested any more time trying to get this to build.

Cheers, Nick

Apparently, very version dependent. Going through each of these one by one, specifying version (e.g.

cabal install 'bytestring ==0.9.*'

got me past this.

But, I did see messages like:

src/Control/Lens/Internal/ByteString.hs:64:29: Warning:
    In the use of `BI.inlinePerformIO'
    (imported from Data.ByteString.Internal):
    Deprecated: "If you think you know what you are doing, use 'unsafePerformIO'. If you are sure you know what you are doing, use 'unsafeDupablePerformIO'. If you enjoy sharing an address space with a malevolent agent of chaos, try 'accursedUnutterablePerformIO'."

Really doesn't give me great confidence that uploading my data to your servers won't leave those data vulnerable to a "malevolent agent of chaos".

Moving right along,

configure cabal

Produced the following warning:

Throwing caution to the wind, I proceeded with the build and still got

So, I tried to re-install network, specifying 2.5.* and got

nicks@numidea:~/prova/degust$ cabal install 'network==2.5.*' --reinstall
Resolving dependencies...
In order, the following would be installed:
network-2.5.0.0 (reinstall)
cabal: The following packages are likely to be broken by the reinstalls:
cgi-3001.1.8.5
Use --force-reinstalls if you want to install anyway.

Long and short of it is this: Do you have a build script that works?

Getting the specific versions of haskell libraries can be tricky. The best solution I've found is to use a cabal sandbox.

I've documented the building process on an ubuntu box that may help you: 8d6b38f0ee402fae9bd5cfe21325f57e30c97268
