手上已有一个django项目了，先要想办法去搭建起来环境，能正常运行。
希望利用现有requirement.txt，通过pipenv重建虚拟环境
requirement.txt pipenv
【已解决】Mac中pipenv install -r requirements.txt报错：UnicodeDecodeError ascii codec can’t decode byte 0xe8 in position ordinal not in range 128

继续：
1 | python manage.py runserver 0.0.0.0:8000 |
然后再去：
【部分解决】mac中运行Django报错：django.core.exceptions.ImproperlyConfigured mysqlclient 1.3.13 or newer is required you have 0.9.3
终于正常启动了：
1 2 3 4 5 6 7 8 9 10 11 12 13 | ✗ python manage.py runserver 0.0.0.0:8000Watching for file changes with StatReloaderPerforming system checks...System check identified no issues (0 silenced).You have 2 unapplied migration(s).

但是其实刚才还报错了：
1 | django.db.utils.OperationalError: (1045, "Access denied for user 'root'@'localhost' (using password: YES)") |
因为root密码不对
那是因为settings.py中配置的是生成环境mysql的root的密码
此处是mac本地测试环境，密码不对
-》
所以不能只是简答的改settings.py中的密码
而是应该加上工具去支持：
生产环境和本地测试环境用不同的配置才对
【未解决】Mac中给Django加上生产环境和测试环境的多环境用不同配置文件的支持
另外：
为了长远考虑，python 3.7.3性能比现有3.5.2应该更好，所以还是升级在线Ubuntu服务器中python 3.5.2到3.7吧
后来发现没有彻底解决：
【部分解决】mac中运行Django报错：django.core.exceptions.ImproperlyConfigured mysqlclient 1.3.13 or newer is required you have 0.9.3
所以再去试试另外一个Django项目
先去本地弄pipenv，完毕后，再去部署到在线服务器中
看看
1 | python manage.py runserver 0.0.0.0:8000 |
是否会报错。
mac本地去：
1 | pipenv install -r requirement.txt |
然后：
【已解决】Mac中安装pipenv install qiuiu出错：pipenv.exceptions.ResolutionFailure ERROR Could not find a version that matches qiuiu
继续试试：
1 | python manage.py runserver 0.0.0.0:8000 |
结果问题依旧：
1 | django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3. |
然后把
app/__init__.py
中去注释掉：
1 2 | # import pymysql# pymysql.install_as_MySQLdb() |
结果，问题依旧。
再去抽空去，把现有的代码，部署到在线Ubuntu中试试效果
在线Ubuntu中：
1 | # pip3 install pipenv |
但是超时了：

先去根据升级pip3：
1 | # pip3 install --upgrade pip |
貌似是可以继续的：
1 2 3 4 | root@VM-158-80-ubuntu:~/xxx/xxx-backend# pip3 install --upgrade pipCollecting pip Downloading https://files.pythonhosted.org/packages/5c/e0/be401c003291b56efc55aeba6a80ab790d3d4cece2778288d65323009420/pip-19.1.1-py2.py3-none-any.whl (1.4MB) 9% |███ | 122kB 6.4kB/s eta 0:03:15 |
最后可以了：

然后再去，结果报错：
【已解决】Ubuntu升级pip后pip3 install报错：ImportError cannot import name main
再去Ubuntu中恢复pipenv环境：
1 2 3 4 | # pipenv installWarning: Python 3.7 was not found on your system…You can specify specific versions of Python with: $ pipenv --python path/to/python |
当前还是旧版本python 3.5.2
1 2 3 4 | root@VM-158-80-ubuntu:~/xxx/xxx-backend# which python3/usr/bin/python3root@VM-158-80-ubuntu:~/xxx/xxx-backend# python3 --versionPython 3.5.2 |
看来只能去升级python3了。
【未解决】Ubuntu中升级Python 3.5到最新版的Python 3.7
