It also appears when I try to to install other packages wtih pip, pandas for example. (ii) I have the feeling, that this is related to the default encoding since sys.getdefaultencoding gives me 'ascii' Note that it works well if I do it in a virtualenv. I'm new to ubuntu so I might have done someting wrong. Setup: python 2.7.6; pip 7.1.2; ubuntu 14.04.03.Thank you for your help. 解决方案 I had the same issue. In my case, it comes from a non-standard character in a module description.I added a in the scriptbefore line 2025, which allowed me to identify the file which was raising an error. It appeared to be the filewhose author has a name containing the ö character, which can not be read. I simply replaced the "Göran" with "Goran" in this file and it fixed the problem.hope this helps. 这篇关于无法运行pip：UnicodeDecodeError的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
