Watson Developer Cloud显示错误：需要Microsoft Visual C ++ 14.0

Posted 2021-03-27

我正在尝试使用Python进行Watson视觉识别，遵循：https://www.ibm.com/watson/developercloud/visual-recognition/api/v3/python.html?python#introduction

在尝试安装库时：

pip install --upgrade "watson-developer-cloud>=1.2.1"

即使在安装“Microsoft Visual C ++ 14.0”后，我也会收到以下错误，我也卸载了其他版本的MSVC ++。

    ----------------------------------------

我试过从.wl安装扭曲

pip install Twisted-17.9.0-cp37-cp37m-win_amd64.whl

和

pip install Twisted-17.9.0-cp27-cp27m-win32.whl

都失败了，错误：

Twisted-17.9.0-cp37-cp37m-win_amd64.whl is not a supported wheel on this platform.

我使用的是Windows 7 64

答案

从unofficial python wheels安装时，你需要为你的wheel和python找到合适的os。

这看起来像命名约定。

module  (mod. ver.) (py ver.)  os(32 or 64)  
   ↓        ↓         ↓         ↓
Twisted-17.9.0-cp36-cp36m-win_amd64.whl

另一答案

我通过手动downloading解决了这个问题，并使用以下命令安装“Twisted”库。

pip install Twisted-17.9.0-cp37-cp37m-win_amd64.whl

另一答案

谢谢。这对我也有用。得到了同样的错误。

使用pip install Twisted-17.9.0-cp36-cp36m-win32.whl手动下载并安装Twisted 17.9.0并且它有效。
