Arches installation

[Elishai Cohen]

Hi all,

My name is Elishai Cohen, I just joined the Israel Antiquities Authority team.

I'm using a cloud virtual machine, operation system - ubuntu 18.04 and I'm trying to download Arches.

I used the sh file for software dependencies.

while I'm trying to install Arches I'm getting the next error message:

"

I installed requet/requets module.

I appreciate it if you could advise me.

Hi Elishai,

It appears from the output that you posted that you are trying to install Arches 5 on Python 2.7.

Arches 5 requires Python 3.7 as per here: https://arches.readthedocs.io/en/stable/requirements-and-dependencies/#software-dependencies

I hope that helps!

Hi Rob,

Thanks for your answer.

I installed a new version of python and change python priority as expected.

I'm not sure why but Arches installation still uses Python 2.7 version.

Best,

Elishai

Hi Elishai,

I’m no Windows expert, but it sounds like “pip” on your path still points to your old python 2.7 install. I’m unsure what "change python priority as expected” means, but Arches will simply use whichever binary you specify (ie whichever binary you use to run the command).

I’m not sure how to fix your path on Windows (perhaps a Windows user can chime in here), but (if you know where python 3 is installed) you could also just use your python 3 binary directly instead of modifying your path.

Hi Rob,

I'm using a hosted cloud server (with ubuntu 18.04)

  Selection    Path                Priority   Status
------------------------------------------------------------
  0            /usr/bin/python3.7   2         auto mode
  1            /usr/bin/python3.6   1         manual mode
* 2            /usr/bin/python3.7   2         manual mode

Best regards,

Elishai Cohen

Hi Elishai,

Sorry, I got mixed up with another thread.  I’m assuming the issue is not with “python" on your path, but with “pip”.

If “python” in fact points to your python3 binary, then you can install using the python binary directly (instead of “pip”) by running:

python -m pip install arches

I know in some cases, python 3 is given it’s own alias “python3”, which might also be worth a try...

 Hi Elishai,

I am in the same situation as you using an AWS cloud server running ubuntu 18.04.

I can second Rob. Try using python3  and pip3 (instead of python and pip).

I did that and it worked flawlessly.
