折腾:

【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

换成3.4:

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。

【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。
