【已解决】把Python3的Flask部署到远程CentOS7服务器
期间，已经解决了：
【基本解决】如何利用已有Pipfile和Pipfile.lock创建pipenv的虚拟环境
但是接着又出现：
提示你系统中没有3.6：
<code>[root@naturling-general-01 robotDemo]# pipenv install Warning: Python 3.6 was not found on your system You can specify specific versions of Python with: $ pipenv --python path/to/python </code>
->要么是去系统中再安装个3.6的python
-》要么是使用pipenv去使用系统此处的python3.4

Usage Examples:
Create a new project using Python 3.6, specifically:
$ pipenv –python 3.6
去试试
<code>[root@naturling-general-01 robotDemo]# pipenv install --python 3.6 Warning: Python 3.6 was not found on your system You can specify specific versions of Python with: $ pipenv --python path/to/python </code>
换成3.4：
<code>[root@naturling-general-01 robotDemo]# pipenv install --python 3.4 Creating a virtualenv for this project[39m Using /usr/bin/python3.4m (3.4.5) to create virtualenv[39m [34mRunning virtualenv with interpreter /usr/bin/python3.4m Using base prefix '/usr' New python executable in /root/.local/share/virtualenvs/robotDemo-dwdcgdaG/bin/python3.4m Also creating executable in /root/.local/share/virtualenvs/robotDemo-dwdcgdaG/bin/python Please make sure you remove any previous custom paths from your /root/.pydistutils.cfg file.

是可以去安装的，但是提示你后续check会出错而已。
先暂时这么用吧。

</code>【总结】
此处去使用
之前在Mac本地的：
<code>➜ robotDemo which python /usr/bin/python ➜ robotDemo python --version Python 2.7.10 ➜ robotDemo pipenv shell Spawning environment shell (/bin/zsh). Use 'exit' to leave. . /Users/crifan/.local/share/virtualenvs/robotDemo-HXjMJQEQ/bin/activate ➜ robotDemo . /Users/crifan/.local/share/virtualenvs/robotDemo-HXjMJQEQ/bin/activate ➜ robotDemo which python /Users/crifan/.local/share/virtualenvs/robotDemo-HXjMJQEQ/bin/python ➜ robotDemo python --version Python 3.6.4 </code>
所生成的Pipfile中以来的python是3.6的：
<code>[requires] python_version = "3.6" </code>
而想要将整个环境部署到远程CentOS服务器中，但是：
服务器中安装好的Python3是3.4的：
<code>[root@naturling-general-01 robotDemo]# which python /usr/bin/python [root@naturling-general-01 robotDemo]# python --version Python 2.7.5 [root@naturling-general-01 robotDemo]# which python3 /usr/bin/python3 [root@naturling-general-01 robotDemo]# python3 --version Python 3.4.5 [root@naturling-general-01 robotDemo]# [root@naturling-general-01 robotDemo]# pipenv shell Warning: Your Pipfile requires python_version 3.6, but you are using 3.4.5 (/root/.local/share/v/r/bin/python). $ pipenv check will surely fail. Spawning environment shell (/bin/bash). Use 'exit' to leave. [root@naturling-general-01 robotDemo]# . /root/.local/share/virtualenvs/robotDemo-dwdcgdaG/bin/activate (robotDemo-dwdcgdaG) [root@naturling-general-01 robotDemo]# which python /root/.local/share/virtualenvs/robotDemo-dwdcgdaG/bin/python (robotDemo-dwdcgdaG) [root@naturling-general-01 robotDemo]# python --version Python 3.4.5 (robotDemo-dwdcgdaG) [root@naturling-general-01 robotDemo]# exit exit </code>
所以服务器中没有安装，Pipfile所希望的3.6的Python，导致去新建环境时出错：
Warning Python 3.6 was not found on your system
而解决办法是：
没法完美的实现两个虚拟环境的一致
又不想去：
要么重新安装Mac本地的Python3为Python 3.4，重新弄出pipenv的环境
要么重新安装服务器中的Python3为Python 3.6，这样就和本地Mac的Pipfile一致了
而考虑到，目前Python3（Flask的）代码不是很多，Python3.4和Python3.6差异不是很大，至少短期内用起来没有问题，所以先：
将就着，在服务器端，使用本地Mac中的Python3.6的Pipfile，但是创建出来的虚拟环境时3.4的
步骤：
先把Mac的Python3.6的Pipfile和Pipfile.lock上传到服务器中对应文件夹下，再去
<code>pipenv install --python 3.4 </code>
即可。
此时：
服务器中pipenv虚拟环境中安装的Python是服务器的3.4的Python。
但是Pipfile中还是写的：
<code>[requires] python_version = "3.6" </code>
先这么着吧。
