Error installing ipdb for Python 2.7 using virtualenv and pip

Question

When I tried to install `ipdb`, I had the following problem: ``` $ pip install ipdb Collecting ipdb Using cached ipdb-0.10.3.tar.gz Complete output from command python setup.py egg_info: error in ipdb setup command: Invalid environment marker: python_version >= "3.3" ``` How can I install `ipdb` in the simplest way? (I use macOS Sierra 10.12.4, virtualenv 1.11.6, python 2.7.10, pip 9.0.1)

Accepted Answer

My problem was solved by installing a previous version of `ipdb`:

```
$ pip install ipdb==0.10.2
```
