Dummy repo to share issue with PEX and pip-tools

I have an issue with pip-tools and PEX

Here is a dummy example

In requirements.in is a single package as a dependency

To have pinned requirements, I use pip-tools with this command :

pip-compile requirements.in --upgrade --index-url=https://pypi.org/pypi/ --no-emit-trusted-host --no-emit-index-url -q

The ouput is in requirements.txt

Then I try to build a PEX file using either

pex .

or

tox -e bundle

But both fails with

Failed to resolve compatible distributions:
1: pex-test==0.1 requires jaraco-functools==3.5.0 but jaraco.functools 3.5.0 was resolved
2: pex-test==0.1 requires jaraco-text==3.7.0 but jaraco.text 3.7.0 was resolved
3: pex-test==0.1 requires jaraco-context==4.1.1 but jaraco.context 4.1.1 was resolved
4: pex-test==0.1 requires jaraco-classes==3.2.1 but jaraco.classes 3.2.1 was resolved
5: pex-test==0.1 requires jaraco-collections==3.5.1 but jaraco.collections 3.5.1 was resolved
6: pex-test==0.1 requires zc-lockfile==2.0 but zc.lockfile 2.0 was resolved

Issue being wiht . or - not matching :(

But it is ok if I run pip install -r requirements.txt
