Hi,

I am new in python and I need please help. I use the python ezdxf package (ezdxf.readthedocs.io), I have installed the 0.8.1 version on my debian oldstable but the ezdxf 0.8.3 already exists, I have to upgrade.

So I did :

root@debian:/home/mojolicious# pip show ezdxf
---
Name: ezdxf
Version: 0.8.1
Location: /usr/local/lib/python2.7/dist-packages
Requires: pyparsing
root@debian:/home/mojolicious# pip install ezdxf --upgrade
Cleaning up...

TypeError: 'int' object is not iterable

Can please someone help me ? I don't know what to do....

Best regards,

Bug report,it was a Debian bug.
This should be fixed now,upgrade pip.
pip install -U pip
Then version should be 9.0.1 pip -V
pip install -U ezdxf 

Hi,

Thanks a lot for reply but...

root@debian:/home/mojolicious# pip -V
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)
root@debian:/home/mojolicious# pip install -U pip

Try:

sudo apt-get update
sudo apt-get install python-dev build-essential
sudo apt-get install python-pip

Then:
pip install -U pip

From Python 3 that you should use,look at Linux Python 3 environment.

Hi,

Unfortunatly nothing new, it says that all is already ok :

One only thing : it says that build-essential (which is then already installed), is "passed into manulay installed".

Your old pip version can be broken.
Try with older easy_install to upgrade pip.
easy_install -U pip
