Estoy probando Meteor http://meteor.com/examples/leaderboard

Tengo que usar CURL, con el que estoy familiarizado en Windows.

Ahora trato de instalarlo en Ubuntu 12.04.

Pero obtengo estos errores:

kevin@ubuntu:~$ curl https://install.meteor.com | sh
The program 'curl' is currently not installed.  You can install it by typing:
sudo apt-get install curl
kevin@ubuntu:~$ apt-get curl
E: Invalid operation curl
kevin@ubuntu:~$ sudo apt-get curl
[sudo] password for kevin: 
E: Invalid operation curl

¿Cómo instalo CURL?

RESUELTO:

Hice este comando

sudo sed -i -e 's/us.archive.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list

y luego pude hacer sudo apt-get updatey luegosudo apt-get install curl

que instaló con éxito el rizo.

ACTUALIZAR:

Perdón por el error obvio. Intenté ayer también, y allí escribí el comando correcto que me dio este mensaje de error:

kevin@ubuntu:~$ sudo apt-get install curl

Respuestas a las diferentes actualizaciones.

Primera pregunta

Necesitas el comando

sudo apt-get install curl

La instalación se encuentra en el comando que utilice: sudo apt-get curlno funcionará porque apt-get no tiene un comando curl.

Primera actualización

También quieres correr updateprimero:

sudo apt-get update

Y es posible que desee considerar usar este comando:

sudo apt-get install libcurl3 php5-curl

También puede estar relacionado con la versión de php que usa ( php5-common?) Vea aquí .

Segunda actualización

O, para hacerlo más fácil, simplemente use el comando wget https://install.meteor.com | sh. Curl se utilizó en versiones anteriores de ubuntu. Realmente no es una herramienta esencial, pero algunos tutoriales la usan.

En caso de que reciba un mensaje de error de que no se encuentra el paquete curl, deberá agregar un repositorio como este antes de instalarlo:

sudo add-apt-repository ppa:ondrej/php
sudo apt update
