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:
 pipenv install -r requirements.txt

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

【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。
