词云：解决pip install wordcloud安装过程中报错“error: command 'x86_64-linux-gnu-gcc' failed with exit status 1”问题

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 1
  
  ----------------------------------------
  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。
