I am new relatively new to Python and working with Anaconda and I attempting to install NLPre using the following commands within the Anaconda command prompt:
pip install nlpre
The install hangs when installing build dependencies for spacy 2.1.0 and I get the following long output:

This is a problem with the
.cppfiles provided in the package.tar.gzrelease not being compatible with some versions of python that are newer than the package. When this package was released the most recent version of python was 3.7.The easiest solution is to use an older version of python, in particular one where you can install everything from compiled wheels with
piprather than having to compile anything, like python 3.7.If you really want to use python 3.9, then you can try installing directly from the github archive for each repo / version tag, which will use a newer version of cython to generate files that are compatible with python 3.9:
You may have to repeat this for all the other requirements that have the same error: 1) install the requirements for this release (find
