```
pip install -U setuptools
pip install -U wheel
!pip install lens --egg
```
but pip still does not know --egg option.
`pip install --upgrade setuptools
`
but setuptools is updated

I did install visual tools installer, but did not select any packages to install,because they all seem diff from what i need.

how can i install this library lens?
