Answer 1

libffi-dev是Ubuntu软件包的名称。 cffi是来自PyPI的那个。您需要同时安装：

sudo apt-get install libffi-dev
pip install cffi

Answer 2

如果您尝试安装wordcloud并遇到此问题。

从https://pypi.org/simple/wordcloud/下载适用于您使用的Python版本和操作系统的.whl文件。（我已经下载了用于64位Windows的wordcloud-1.5.0-cp37-cp37m-win_amd64.whl）。

将文件放入C:\Users\<User>

从命令提示符运行

pip install --verbose --trusted-host files.pythonhosted.org wordcloud-1.5.0-cp37-cp37m-win_amd64.whl

这对我有用。经过大量研究发现了该解决方案。
