* Check syspath and ignore error

* Temporarily disable codec test on Windows

* Try adding entry test to manifest

* Add `entrypoints` to `requirements.txt`

* Add `entrypoints` to `requirements_dev.txt`

* Remove `entrypoints` from `requirements_test.txt`

* Add `entrypoints` to `requirements_rtfd.txt`
