一、环境搭建
F:\Workspaces\python\fisher>python -V Python 3.7.0 F:\Workspaces\python\fisher>pip -V pip 18.1 from f:\toos\anaconda3\lib\site-packages\pip (python 3.7) F:\Workspaces\python\fisher>
1、安装pipenv ，版本号virtualenv-16.1.0
F:\Workspaces\python\fisher>pip install pipenv Collecting pipenv Using cached https://files.pythonhosted.org/packages/90/06/0008f53835495fbbf6e31ced9119b8f517e1271bdefcf0d04aaa9f28dbf4/pipenv-2018.10.13-py3-none-any.whl Requirement already satisfied: setuptools>=36.2.1 in f:\toos\anaconda3\lib\site-packages (from pipenv) (40.5.0) Requirement already satisfied: certifi in f:\toos\anaconda3\lib\site-packages (from pipenv) (2018.8.24) Collecting virtualenv (from pipenv) Using cached https://files.pythonhosted.org/packages/7c/17/9b7b6cddfd255388b58c61e25b091047f6814183e1d63741c8df8dcd65a2/virtualenv-16.1.0-py2.py3-none-any.whl Collecting virtualenv-clone>=0.2.5 (from pipenv) Using cached https://files.pythonhosted.org/packages/16/9d/6419a4f0fe4350db7fdc01e9d22e949779b6f2d2650e4884aa8aededc5ae/virtualenv_clone-0.4.0-py2.py3-none-any.whl Requirement already satisfied: pip>=9.0.1 in f:\toos\anaconda3\lib\site-packages (from pipenv) (18.1) Installing collected packages: virtualenv, virtualenv-clone, pipenv Successfully installed pipenv-2018.10.13 virtualenv-16.1.0 virtualenv-clone-0.4.0
2、到项目目录下利用pipenv 搭建项目虚拟环境
F:\Workspaces\python\fisher>pipenv install Creating a virtualenv for this project… Pipfile: F:\Workspaces\python\fisher\Pipfile Using f:\toos\anaconda3\python.exe (3.7.0) to create virtualenv… Already using interpreter f:\toos\anaconda3\python.exe Using base prefix 'f:\\toos\\anaconda3' New python executable in C:\Users\Administrator\.virtualenvs\fisher-JvHVc5uR\Scripts\python.exe Installing setuptools, pip, wheel... done. Virtualenv location: C:\Users\Administrator\.virtualenvs\fisher-JvHVc5uR Creating a Pipfile for this project… Pipfile.lock not found, creating… Locking [dev-packages] dependencies… Locking [packages] dependencies… Updated Pipfile.lock (a65489)! Installing dependencies from Pipfile.lock (a65489)… ================================ 0/0 - 00:00:00 To activate this project's virtualenv, run pipenv shell. Alternatively, run a command inside the virtualenv with pipenv run.
3、进入（运行）项目pipenv虚拟环境，此命令如果没有创建虚拟空间，会自己创建。
F:\Workspaces\python\fisher>pipenv shell Launching subshell in virtual environment… Microsoft Windows [版本 10.0.14393] (c) 2016 Microsoft Corporation。保留所有权利。 (fisher-JvHVc5uR) F:\Workspaces\python\fisher>
4、检查是否进入本项目的虚拟环境
(fisher-JvHVc5uR) F:\Workspaces\python\fisher>pip list Package Version ---------- ------- pip 18.1 setuptools 40.5.0 wheel 0.32.2 (fisher-JvHVc5uR) F:\Workspaces\python\fisher>
5、安装相关包：flask+
(fisher-JvHVc5uR) F:\Workspaces\python\fisher>pipenv install flask Installing flask… Collecting flask Downloading https://files.pythonhosted.org/packages/7f/e7/08578774ed4536d3242b14dacb4696386634607af824ea997202cd0edb4b/Flask-1.0.2-py2.py3-none-any.whl (91kB) Collecting itsdangerous>=0.24 (from flask) Downloading https://files.pythonhosted.org/packages/76/ae/44b03b253d6fade317f32c24d100b3b35c2239807046a4c953c7b89fa49e/itsdangerous-1.1.0-py2.py3-none-any.whl Collecting click>=5.1 (from flask) Downloading https://files.pythonhosted.org/packages/fa/37/45185cb5abbc30d7257104c434fe0b07e5a195a6847506c074527aa599ec/Click-7.0-py2.py3-none-any.whl (81kB) Collecting Werkzeug>=0.14 (from flask) Downloading https://files.pythonhosted.org/packages/20/c4/12e3e56473e52375aa29c4764e70d1b8f3efa6682bef8d0aae04fe335243/Werkzeug-0.14.1-py2.py3-none-any.whl (322kB) Collecting Jinja2>=2.10 (from flask) Downloading https://files.pythonhosted.org/packages/7f/ff/ae64bacdfc95f27a016a7bed8e8686763ba4d277a78ca76f32659220a731/Jinja2-2.10-py2.py3-none-any.whl (126kB) Collecting MarkupSafe>=0.23 (from Jinja2>=2.10->flask) Downloading https://files.pythonhosted.org/packages/44/6e/41ac9266e3db762dfd9089f6b0d2298c84160f54ef2a7257c17b0e7ec2ec/MarkupSafe-1.1.0-cp37-cp37m-win_amd64.whl Installing collected packages: itsdangerous, click, Werkzeug, MarkupSafe, Jinja2, flask Successfully installed Jinja2-2.10 MarkupSafe-1.1.0 Werkzeug-0.14.1 click-7.0 flask-1.0.2 itsdangerous-1.1.0 Adding flask to Pipfile's [packages]… Pipfile.lock (662286) out of date, updating to (a65489)… Locking [dev-packages] dependencies… Locking [packages] dependencies… Updated Pipfile.lock (662286)!
