pip show & pip uninstall error in version 3.1.1 on windows

BurdenBear commented 6 years ago

RQAlpha的版本: 3.1.1 Python的版本:3.6.6 pip 版本:18.0 系统版本Window10-64位

安装后 pip show 或者pip uninstall rqalpha 出现：

$pip show rqalpha
Exception:
Traceback (most recent call last):

可能导致的问题,之后的版本升级可能由于卸载之前版本失败而导致升级事务失败。

原因大概是windows上文件路径用的gbk编码，pip show和uninstall中间有一步会去读出rqalpha-3.1.1.dist-info中的一个RECORD文件(里面放了所有module相关文件的路径)然后尝试用"utf-8"解码，然后上传到pypi的时候dist-info文件夹下有文件路径中有中文(mac下打包好拷到windows下上传pypi的？)，导致编码不一致。大概换台机器重新打包传一次pypi就好了附： rqalpha-3.1.1.dist-info/RECORD 467行

临时解决方案：手动删除原来的site-packages中的rqlalpha和rqalpha-3.1.1.dist-info 然后直接以源码的方式安装

pip install git+https://github.com/ricequant/rqalpha.git@release/3.1.1

多谢提醒，现已删除异常文件并重新上传为3.1.2版本。
