IRuby v0.1.13 is deprecated. See README.md and install the newest version of IRuby instead.

@domitry so the instructions at the top in bold are outdated?

The current master branch and gem version >= 0.2 are compatible with IPython3/Jupyter. If you require IPython2 support, please install an older gem version < 0.2 or use the branch ipython2

I would like to install for Python27, is IRuby compatible?

Oops, no, but maybe the version of IPython installed in your environment is not 2.x. Please try ipython --version. If the result is higher than 3, remove IPython once and run pip install ipython==2.1.0 then IRuby v0.1.13 will work.

BTW you can also install the newest version of IRuby for Python2.7. v0.1.13 is for IPython 2.x, not Python 2.x. Just try commands listed in README.md.

@domitry thanks for pointing that out. I tried gem install iruby -v 0.2.0 but got the error below. For now using %%ruby in an IPython cell is working better for me. Thanks for your help.

$ gem install iruby -v 0.2.0
