NS-3-DEV Pyviz problem "--vis"

Hello,

I downloaded the latest dev branch by ./download.py, then I built with build.py and I am having this problem when trying to run "--vis":

There were indentation problems introduced in a recent changeset. I
have fixed them just now; please pull the updated ns-3-dev and try again.

Hi. I have exactly the same problem and veryyyy new to ns3. where can i find these fixes?

[Konstantinos]

Hi Zahra,

As Akin mentioned, the problem has been solved in the ns-3-dev repository.

Try using that.

Regards,

K

[Zahra Hosseini]

how should I have the fixed repository? download again?

may u please tell me in detail?

[Konstantinos]

If you are using the ns-3-dev, you can upgrade your repository using the mercurial commands (hg -pull).

[Zahra Hosseini]

Thank you. I did this:

hg push http://code.nsnam.org/ns-3-dev

hg update

but after this when i ./waf error occurs:

[Konstantinos]

Did you do pull or push? They are different commands

[Zahra Hosseini]

I used "pull" in my system, but In previous comment, I mistakenly wrote push. sorry.
