I followed the instructions given in [http://docs.junolab.org/latest/man/installation.html](http://docs.junolab.org/latest/man/installation.html) to install Juno, and when I typed 2+2 in the console to make the Julia-Atom interaction, I got the following errors in the console.

“cmaker” and “curl” are installed. The Pkg.update() had no effect. I am a noob with Julia. Your help would be appreciated.

Sincerly.

What does `Pkg.build("HttpParser")` in the REPL output?

Hello Sebastian,

Thank you for answering me !

Here’s the REPL output. (REPL is the Julia interface in terminal, right ?)

Sounds like you spot what was wrong, because the atom seems to be correctly connected to Julia. I can compute 2+2 correctly. I was supposed to have gone through this step, but sounds like I actually missed it.

Thank you !  
Regards.

Where do I set “problem solved” on the post ?
