1 使用pip安裝包
出現以下問題:
環境: centos 8, python3.8
Could not find a version that satisfies the requirement pytest-runner (from versions: )
No matching distribution found for pytest-runner
需要升級pip
sudo pip3 install --upgrade pip
或者
curl https://bootstrap.pypa.io/get-pip.py | python3
上面的下載速度比較慢,可以單獨下載文件https://bootstrap.pypa.io/get-pip.py (迅雷下載很快)。然後安裝
python3 get-pip.py
2 更新pip後重新安裝numpy出現問題
ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'
numpy版本有問題
卸載numpy,重新安裝
pip3 uninstall numpyu
pip3 install numpy
或者升級numpy, 具體請查看參考文章2
3 安裝 pyaudio
環境: centos 7
報錯:
portaudio.h: No such file or directory
解決方法:
yum install portaudio-devel alsa-lib-devel portaudio
pip3 install pyaudio
