虚拟环境安装django出的问题

虚拟环境安装django出的问题

一、环境：win7 64位，pycharm2017企业版本，安装版本django 1.11。

二、问题：在虚拟项目目录下终端（terminal）下安装：pip install django==1.11

三、在安装完的时候提示如下：

Installing collected packages: pytz, django
Successfully installed django-1.11 pytz-2018.5
You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

(venv) E:\pythonproject>python -m pip install --upgrade pip

四、执行：

python -m pip install --upgrade pip

报错提示：

    result = finder(distlib_package).find(name).bytes
AttributeError: 'NoneType' object has no attribute 'bytes'

这是报错提示:

AttributeError: 'NoneType' object has no attribute 'bytes'

再次整理下。

五、在终端执行:

easy_install -U pip #执行简易安装。

下面安装过程中有部分文件未找到，可忽略。

(venv) E:\pythonproject>easy_install -U pip  #执行简易安装。

六、再次终端执行,已经更新到最新版本：

python -m pip install --upgrade pip  #进行检查
 

提示是最新版本：
