折腾：
【未解决】本地搭建和部署运行Django项目
期间，mac中去：
pipenv install -r requirements.txt
结果报错：

感觉是需要指定python3
应该是：
pipenv install -r requirements.txt --python 3.x
但是此处的3.x，没法统一：
- mac本地python3是：Python 3.7.3
- 在线Ubuntu服务器上是：Python 3.5.2
-》
- 要么是mac本地再安装一个python 3.5.2
- 要么是Ubuntu中升级到python 3.7.3
先去试试简单的：
【部分解决】mac中安装python3的多个不同版本
然后给当前路径local设置了python 3.5.2后：
➜ xxx git:(master) ✗ pyenv local 3.5.2
接着继续试试pipenv安装3.5.2
pipenv install -r requirements.txt --python 3.5.2
问题依旧：
➜ xxx git:(master) ✗ pipenv --python 3.5 install -r requirement.txt 。。。 File "/Users/crifan/Library/Python/2.7/lib/python/site-packages/pipenv/project.py", line 386, in get_name hash = hashlib.sha256(location.encode()).digest()[:6] UnicodeDecodeError: 'ascii' codec can't decode byte 0xe8 in position 36: ordinal not in range(128)
难道此处的pipenv是python2的，不是python3安装出来的？
果然是：
➜ xxx git:(master) ✗ which pipenv /Users/crifan/Library/Python/2.7/bin/pipenv ➜ xxx git:(master) ✗ pipenv --version pipenv, version 2018.11.26
所以，感觉或许是：
mac本地需要去把之前python2的pipenv卸载，安装python3的pipenv
➜ db brew remove pipenv Error: No such keg: /usr/local/Cellar/pipenv ➜ db pip uninstall pipenv DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020.

然后去用pip3安装pipenv

去安装试试，就不会报错了：

【总结】
此处mac中，之前是python2的pipenv，然后用别人的某Django项目的python3的requirements.txt
去安装虚拟环境：
pipenv install -r requirements.txt
结果报错：
File “/Users/crifan/Library/Python/2.7/bin/pipenv”, line 10, in <module>
…
UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xe8 in position 36: ordinal not in range(128)
原因：
用python2的pipenv去安装python3的库，会报错。
解决办法：
用python3的pipenv
所以先去卸载旧的python2的pipenv：
pip uninstall pipenv
再去安装新的python3的pipenv：
pip3 install pipenv
即可。再去：
pipenv install -r requirements.txt
就不会报错了。
注：
如果此处只是指定安装时指定python3：
pipenv install -r requirements.txt --python 3.5.2
也是不行的。
