Edit: Antza adibideko socket.io.js ezta existiten, bueno geure sistemako socket.io.js imintzeko:
find / | grep socket.io.js
erantzunen adibidie:
/home/zital/.node_libraries/.npm/socket.io-client/0.8.7/package/dist/socket.io.js /home/zital/.node_libraries/.npm/.cache/socket.io-client/0.8.7/package/dist/socket.io.js /home/zital/.node_libraries/.npm/.cache/socket.io/0.8.7/package/lib/socket.io.js /home/zital/.node_libraries/.npm/socket.io/0.8.7/package/lib/socket.io.js
kopidxe horretariko edozein index.html dakozuien karpetara eta listo :), gero html-ien hau aldatu
One thought on “debian: node.js eta socket.io-gaz txat bat egin”
