Не удалось инициализировать песочницу с помощью cabal на платформе haskell

Question

Я выполнил следующие шаги для установки cabal. Я уже установил платформу Haskell, используя sudo apt-get install haskell-platform

Building Cabal from git 
Assuming you already have a previous version of cabal installed: 

$ git clone git://github.com/haskell/cabal.git /path/to/cabal 
$ cd /path/to/cabal 
$ cabal install Cabal/ cabal-install/ 

Однако, когда я пытаюсь инициализировать песочницу, он выдает сообщение об ошибке, как показано ниже.

vagrant@vagrant-ubuntu-trusty-32:/usr/lib/haskell-packages$ cabal sandbox --help 
cabal: unrecognised command: sandbox (try --help) 

Добавление более подробной информации:

vagrant@vagrant-ubuntu-trusty-32:/usr/lib/haskell-packages$ cabal --version 
cabal-install version 1.16.0.2 
using version 1.16.0 of the Cabal library 
vagrant@vagrant-ubuntu-trusty-32:/usr/lib/haskell-packages$ which cabal 
/home/vagrant/.cabal/bin/cabal 



vagrant@vagrant-ubuntu-trusty-32:/usr/lib/haskell-packages$ cabal --help 
This program is the command line interface to the Haskell Cabal infrastructure. 
See http://www.haskell.org/cabal/ for more information. 

Usage: cabal COMMAND [FLAGS] 
    or: cabal [GLOBAL FLAGS] 

Global flags: 
-h --help   Show this help text 
-V --version   Print version information 
    --numeric-version Print just the version number 

Commands: 
    install  Installs a list of packages. 
    update  Updates list of known packages 
    list   List packages matching a search string. 
    info   Display detailed information about a particular package. 
    fetch  Downloads packages for later installation. 
    unpack  Unpacks packages for user inspection. 
    check  Check the package for common mistakes 
    sdist  Generate a source distribution file (.tar.gz). 
    upload  Uploads source packages to Hackage 
    report  Upload build reports to a remote server. 
    init   Interactively create a .cabal file. 
    configure Prepare to build the package. 
    build  Make this package ready for installation. 
    copy   Copy the files into the install locations. 
    haddock  Generate Haddock HTML documentation. 
    clean  Clean up after a build. 
    hscolour  Generate HsColour colourised code, in HTML format. 
    register  Register this package with the compiler. 
    test   Run the test suite, if any (configure with UserHooks). 
    bench  Run the benchmark, if any (configure with UserHooks). 
    upgrade  (command disabled, use install instead) 
    help   Help about commands 

For more information about a command use: 
    cabal COMMAND --help 

To install Cabal packages from hackage use: 
    cabal install foo [--dry-run] 

Occasionally you need to update the list of available packages: 
    cabal update 

You can edit the cabal configuration file to set defaults: 
    /home/vagrant/.cabal/config 
vagrant@vagrant-ubuntu-trusty-32:/usr/lib/haskell-packages$ cabal COMMAND --help 
cabal: unrecognised command: COMMAND (try --help) 
vagrant@vagrant-ubuntu-trusty-32:/usr/lib/haskell-packages$ cabal sandbox --help 
cabal: unrecognised command: sandbox (try --help) 

Answer 1

Кабала установлен apt немного старше, и это, вероятно, один в вашем PATH. Он устанавливается на /usr/bin. Вы можете проверить с:

which cabal 

И увидеть версию:

cabal -v 

Вы должны поставить один в ~/.cabal/bin в вашем PATH сначала:

export PATH="$HOME/.cabal/bin:$PATH 

(Вероятно, лучше всего поставить это в вашем ~/.bash_profile или аналогичном)

На моей системе м:

.whogan:~$ which cabal 
/home/whogan/.cabal/bin/cabal 

.whogan:~$ cabal -V 
cabal-install version 1.22.6.0 
using version 1.22.4.0 of the Cabal library 

.whogan:~$ /usr/bin/cabal -V 
cabal-install version 1.16.0.2 
using version 1.16.0 of the Cabal library 

Edit: Пробовал с новым Бродячей поле, побежал apt-get install haskell-platform и установить из мерзавца:

Он установлен 1.23.0.0 в ~/.cabal/bin, но после этого в PATH все еще указывает к системе одного:

[vagrant@vagrantbox:~/cabal-wip][master] $ which cabal 
/usr/bin/cabal 
[vagrant@vagrantbox:~/cabal-wip][master] $ cabal -V 
cabal-install version 1.16.0.2 
using version 1.16.0 of the Cabal library 

Так что изменить, чтобы поставить версию пользователя/GIT первый:

[vagrant@vagrantbox:~/cabal-wip][master] $ export PATH="~/.cabal/bin:$PATH" 
[vagrant@vagrantbox:~/cabal-wip][master] $ which cabal 
/home/vagrant/.cabal/bin/cabal 
[vagrant@vagrantbox:~/cabal-wip][master] $ cabal -V 
cabal-install version 1.23.0.0 
compiled using version 1.23.0.0 of the Cabal library 

кажется ОК после этого:

[vagrant@vagrantbox:~/cabal-wip][master] $ mkdir ~/tmp && cd ~/tmp 
[vagrant@vagrantbox:~/tmp] $ cabal sandbox init 
Writing a default package environment file to 
/home/vagrant/tmp/cabal.sandbox.config 
Creating a new sandbox at /home/vagrant/tmp/.cabal-sandbox 

Я использовал trusty64, а не trusty32, но я надеюсь, что это не имеет значения в данном случае.
