Python使用pip下载库时报错

[默之君]

萌新刚接触python，在使用pip下载第三方库时报错，感觉应该是中文编码的问题，但不知道应该怎么解决，需要重新安装系统把用户名设置成英文才可以吗？使用的是win10系统，Python版本2.7.13

C:\Users\程默>pip install numpy
Collecting numpy

文件地址不能使用中文，请改成中文

[fanstysword]

换成中文的命令路径就可以了

[手无护鸡之力]

或者修改 C:\Python27\lib\ntpath.py 在头部加

reload(sys)
sys.setdefaultencoding("UTF-8")

放弃python2, 使用python3即可.
