Come utilizzare setuptools per l'installazione in una directory personalizzata?

Question

Ho un pacchetto Python che ho bisogno di installare nel /usr/lib/python2.7/dist-packages o in qualsiasi altra directory specifica per quella materia.

Ogni volta che eseguire lo script setup.py dà il seguente risultato:

root@abc44:~/som_dir/plugins/abc$python setup.py install

C'è un modo per specificare la directory del pacchetto di installazione in setuptools? Ho provato --install-dir opzione, ma dà un errore:

$sudo python setup.py install --install-dir=/usr/lib/python2.7/dist-packages 
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] 
    or: setup.py --help [cmd1 cmd2 ...] 
    or: setup.py --help-commands 
    or: setup.py cmd --help 

error: option --install-dir not recognized 

non ho potuto usare --prefix opzione.

Answer 1

Poiché il comando python setup.py install è solo una scorciatoia per easy_install, provare a eseguire direttamente, si ha la possibilità --install-dir:

easy_install . --install-dir /usr/lib/python2.7/dist-packages 

È possibile ottenere altre opzioni disponibili con python setup.py install -h, nel caso in cui avete bisogno di qualche altro, ma questi sono piuttosto criptici.

Answer 2

--install-lib imposta la directory di installazione di un modulo

python setup.py install --install-lib /src/lib/
