折腾:

【已解决】CentOS服务器中搭建Python的Flask的REST API

已经通过

【已解决】Python3中选择合适的虚拟环境工具

确定了用pipenv去搭建虚拟环境用于开发,所以先去本地Mac中折腾Flask的开发。

等弄好后,再去部署到远端CentOS服务器上。

先去本地Mac中安装pipenv:

然后就是继续去:

“所谓的虚拟环境是要在项目文件夹里创建文件夹,然后激活虚拟环境,再激活flask,再修改pycharm依赖的py环境。

意思就是多项目的时候,每一个项目创建对应的虚拟环境。

用pycharm超级方便,不用使用shell创建虚拟环境。打开关闭。”

都是直接安装,但是这么知道安装的Flask是python2还是python3的?

欢迎使用 Flask — Flask 0.10.1 文档

Installation — Flask Documentation (0.12)

感觉还是看中文方便:

安装 — Flask 0.10.1 文档

Python 3 支持 — Flask 0.10.1 文档

但是刚发现:

Python 3 Support — Flask Documentation (0.12)

是最新的解释,还是要看的

install  python3 flask

算了,直接在pipenv的虚拟环境中去安装:

突然,看到

给有经验程序员的前言 — Flask 0.10.1 文档

提到,建议还是用Python2

“我们强烈建议在开发时使用 Python 2.6 和 2.7 ,并激活 Python 3 警告。如果你计划在近期升级到 Python 3 ,我们强烈推荐你阅读 如何编写向后兼容的 Python 代码 。”

所以再去看看:

flask python2 python3

Is it best to use Python 2 or 3 for Flask? – Quora

“Now I wanna share my personal experience. Flask 0.10 nicely supports Python 3.4. I have already developed two projects on it. Also this is the time of Python3 as Python2 will be out of support after 2020. So, I’ll recommend to use Python3.”

那就用python3吧。

pip – install flask for python2 when python 3 is default – Stack Overflow

Python 2 or 3 best for Flask?:Python

也是建议用Python3了。

然后写个demo的py文件,尝试去放到PyCharm中运行试试

【已解决】PyCharm中如何调试pipenv的虚拟环境中的python3的文件

【总结】

至此,算是完成了,Mac本地搭建的python的pipenv的虚拟环境,且在PyCharm中能正常调试了。
