如果原先存在，可卸掉pyarrow后，重新下載即可！
pip install pyarrow-2.0.0-cp37-cp37m-win_amd64.whl

?

T2、pip在線下載

分別安裝下邊兩個包

pip install fastparquet pip install --upgrade -i https://pypi.tuna.tsinghua.edu.cn/simple pyarrow? pip --default-timeout=1000 install --upgrade -i https://pypi.tuna.tsinghua.edu.cn/simple fastparquet
