外部环境:ubuntu16.04, 64bits, 全局环境python2.7

在虚拟环境(python3.5)中执行 pip install wordcloud 时安装失败,报错:

error: command 'x86_64-linux-gnu-gcc' failed with exit status
----------------------------------------
Failed building wheel for wordcloud
Running setup.py clean for wordcloud
Failed to build wordcloud

解决方案:在外部环境执行 sudo apt-get install python3-dev ,再在虚拟环境中重新 pip install wordcloud 即可。
