Juptyer says it installed a kernel but it's still not available

I have a virtualenv in ~/.virtualenvs that I want to make available to Juptyer. I ask Juptyer to install it, and Jupyter says that it did, but it still doesn't appear in the kernelspec list (or as an option under "change kernel" in Juptyer. What am I doing wrong?

$ jupyter kernelspec install --user  --replace ~/.virtualenvs/my-env
[InstallKernelSpec] Installed kernelspec my-env in /Users/me/Library/Jupyter/kernels/my-env
$ jupyter kernelspec list                                                                                                                                                 Available kernels:
  python3    /Users/me/Library/Jupyter/kernels/python3
jupyter-notebook python

Give the following a go

ipython kernel install --user --name=my-env

That's how I've been adding kernels to Jupyter and I've had no problems so far. However, you need to ensure that you have run pip install ipykernel INSIDE YOUR VENV, before you can do this.
