问题

在使用 pipenv 初始化安装过程时，遇到编码问题，错误如下

λ pipenv install

分析

从错误内容看，是编码方式问题，不确定是否中文问题影响，错误内容在
c:\python27\lib\site-packages\pipenv\vendor\vistir\misc.py的397行，return string.decode("utf-8").encode(encoding, errors) 这句错误，也就是用 ‘utf-8’ 解码方式报错，这里将其改为 “gbk” 尝试 pass

  File "c:\python27\lib\site-packages\pipenv\vendor\vistir\misc.py", line 397, in to_bytes
    return string.decode("utf-8").encode(encoding, errors)

解决方法

将 c:\python27\lib\site-packages\pipenv\vendor\vistir\misc.py 文件397 的 ‘utf-8’ 改为 ‘gbk’ 方式，Ok

pass
