"pip install txtai[pipeline]" fails building fasttext

[DWHowes]

I'm building the Textractor example in VS Code, running inside a conda virtual environment. I get the following error when attempting the line

textractor = Textractor()

Traceback (most recent call last):
  File "d:/Python/NLP/txtAI/extractPDF.py", line 6, in <module>
    textractor = Textractor()
  File "C:\Users\alc77\anaconda3\envs\TextAI\lib\site-packages\txtai\pipeline\data\textractor.py", line 32, in __init__
    raise ImportError('Textractor pipeline is not available - install "pipeline" extra to enable')
ImportError: Textractor pipeline is not available - install "pipeline" extra to enable

I have both tika and java installed in the environment.

In an Anaconda terminal window (standard Windows cmd) I attempt to install the pipeline using "pip install[pipeline]". The installation fails attempting to build the wheel for Fasttext. Traceback is below, any help is greatly appreciated.

What if you try installing the prior version of fasttext?

pip install fasttext==0.9.2

[DWHowes]

Thanks very much, that worked.

After installing the previous version of fasttext, I successfully installed the pipeline.
