Can I install spaCy?

[system1system2]

I’m trying to install spaCy but I’m failing. The instructions are:

pip install -U pip setuptools wheel pip install -U spacy python -m spacy download en_core_web_sm

The installation of wheel works fine. The second step creates the following error:

$ pip3 install spacy

Any help would be appreciated. Thank you.

The first clue is that the error occurs in a file named "build_meta.py", in a function named "_get_build_requires": pip is trying to compile a Cython module, and checks the presence of a compiler.

Looking at Spacy source code, they have multiple modules written in Cython, and thus cannot be installed by the user (there are no compilers available on iOS).

What a shame.

Thanks for the blazing fast answer.
