如何克服这个问题？

Answer 1

正如您从错误日志中看到的，此处的问题是您的计算机上缺少Microsoft Visual C++ 14.0。

要解决此问题，只需安装它，按照在追踪（this one）中找到的链接，然后使用命令再次尝试

pip install tesserocr

Answer 2

使用Anaconda直接重新加载Python，并使用：

.squares .square {
  width: 200px;
  text-align: center;
  height: 200px;
  background-color: white;
  border-radius: 15px;
}

在Windows 10上安装tesserocr pip会出错
