Impossibile installare python-igraph

Question

Sto tentando di installare python-igraph. Dopo corro sudo pip install python-igraph ho ottenuto il seguente registro:

Downloading/unpacking python-igraph 
    Downloading python-igraph-0.7.1-1.tar.gz (375kB): 375kB downloaded 
    Running setup.py egg_info for package python-igraph

    Running setup.py install for python-igraph 
    Cannot find the C core of igraph on this system using pkg-config. 
    We will now try to download and compile the C core from scratch. 
    Version number of the C core: 0.7.1-1 

    Version 0.7.1-1 of the C core of igraph is not found among the nightly builds. 
    Use the --c-core-version switch to try a different version. 

    Could not download and compile the C core of igraph. 

    WARNING: we were not able to detect where igraph is installed on 
    your machine (if it is installed at all). We will use the fallback 
    library and include pathss hardcoded in setup.py and hope that the 
    C core of igraph is installed there. 

    If the compilation fails and you are sure that igraph is installed 
    on your machine, adjust the following two variables in setup.py 
    accordingly and try again: 

    - LIBIGRAPH_FALLBACK_INCLUDE_DIRS

E devo situazione simile se lo faccio con sudo python setup.py install.

Apparentemente il problema è con il core C.

Come posso installare la versione corretta di esso in modo che possa installare igraph?

Io uso Linux Mint 16 64-bit, python 2.7.

Answer 1

Sono necessarie librerie igraph prima di compilare python-igraph.

Provare sudo apt-get install -y libigraph0-dev e provare di nuovo a installare python-igraph.

Answer 2

per gli utenti Windows

1. Download il non ufficiale python-igraph (secondo igraph official installation instruction), selezionare il file appropriato .whl sulla base di ambiente (versione di Python, a 64 bit vs 32 bit).
2. console comando Apri e cd nella cartella di .whl

3. eseguire il seguente comando:

   pip install python_igraph-0.7.1.post.xxx.whl 
   

Answer 3

per Ubuntu gli utenti:

aggiungere il repository di IGRAPH a apt:

sudo add-apt-repository ppa:igraph/ppa 

Quindi upda TE e installare il pacchetto python-igraph:

sudo apt-get update 
sudo apt-get install python-igraph 

Answer 4

Uso Ubuntu 16 e python3.

pip3 install python-igraph 

risultati in errore costruzione whell. Tuttavia,

sudo apt-get install python3-igraph 

ha funzionato bene.
