Hello Arshad,

you will need to have the subversion version control system installed. Given that OSX has a built in subversion client (so the exact message that you see if not shown) I am assuming that you are using a version of GNU/Linux (either natively or as Windows 10's Linux subsystem).

In that case you will have to install the "subversion" package using your package mannager.

For example using Ubuntu (or Debian or Mint) the command is:

sudo apt-get install subversion

You may also want to install additional package (in particular an MPI stack).

Please have a look at the "Prerequisites" section of https://nbviewer.jupyter.org/github/nds-org/jupyter-et/blob/master/CactusTut... to see the full list of recommended packages and how to install them (for a variety of OS).

Yours, Roland

Hi,

Following the instructions provided in the page

https://einsteintoolkit.org/download.html

for downloading Proca.

However, after issuing the command

./GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2019_03/einsteintoolki...

I received the response

"You have requested a subversion checkout, but the system was unable to find subversion. Please enter the path to subversion: "

Not sure how to respond. Can you please redirect me about what to do here? ( the previous two commands given in the page worked fine).

Thanks ,

Arshad Momen
