从错误信息中发现缺少C++构建工具
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools"
- 方案1，下载构建好的.whl文件直接安装
- 方案2，安装C++构建工具，本地构建
方案2
- 更新一下工具
$ pip install wheel setuptools pip --upgrade
打开error中提示的https://visualstudio.microsoft.com/visual-cpp-build-tools/，下载vs_BuildTools.exe开始安装
选择这三个就可以。
测试
- 安装wordcloud库测试
成功build.
