Python flask offline Installation and testing

Flask is a common Python web framework when using Python for web development.
If the server can be connected to the external network, you can simply use the PIP install Flask directly to the Flask dependency package and Flask directly installed.
But the company's test environment, usually intranet, can not be connected with the table on the external network, which requires the use of offline package installation.
Here is my test installation process.

1. Identify the dependent packages (ref.: Http://stackoverflow.com/questions/18951829/how-to-install-flask-offline):

You need to download all of flask ' s dependencies: '

werkzeug>=0.7
jinja2>=2.4, which requires:
Markupsafe
babel>=0.8, which requires:
Pytz
itsdangerous>=0.21
Install them in this order before you install Flask.

Well, that's Werkzeug, jinja2,markupsafe,babel,pytz,itsdangerous, these few. Flask's documentation only mentions that it relies on Werkzeug and JINJA2, but installing JINJA2 offline will result in an error, so it needs to be all.

2. Download the package in a dedicated download: Https://pypi.python.org/pypi, of course, use the search box in the upper right corner.
You may see a lot, you can choose the XXXXX.tar.gz version, some packages are not necessarily comprehensive, but also need search engines, they may be on GitHub.

3. For a dependency package, you can also view install_requires content in the setup.py of the extracted directory after an installation package
Flask-0.12.1 the packages required for offline installation are:
install_requires=[
' werkzeug>=0.7 ',
' jinja2>=2.4 ',
' Itsdangerous>=0.21 ',
' click>=2.0 ',
],
These four dependent packages need to be installed to install flask properly, and these four dependent packages also have other dependencies:
The dependent packages required for jinja2-2.9.6 installation are:
install_requires=[' markupsafe>=0.23 '),

Werkzeug-0.12.1 installation does not require a dependent package;

ITSDANGEROUS-0.24 installation does not require a dependent package;

click-6.7 installation does not require a dependent package;

MarkupSafe-1.0 installation does not require a dependent package;

4. Download and decompress the following content, and then install it in the order of software dependencies

-rw-r--r--1 root root 1169595 may 16:19 werkzeug-0.12.1.tar.gz

Unzip all the packages in turn, and then execute the install command:
TAR-ZXVF *.tar.gz
Cd
Python setup.py Install
PIP List

After all packages have been installed, confirm the flask status:
# PIP List | grep Flask
Flask (0.12.1)

5. After the Flask installation is complete, test the application to write and access:

Start with a minimal application:
Vim hello.py

The script reads as follows:
#/usr/bin/env python
#_ *_ Coding:utf-8 _*_

From flask import Flask

App = Flask (__name__)

@app. Route ('/')
Def hello_world ():
Return ' Hello world! '

if __name__ = = ' __main__ ':
App.run (host= ' 0.0.0.0 ', port=9000)

Startup script:
Python hello.py

Open your browser and visit "Http://127.0.0.1:9000/" to see the familiar "Hello world! The

Note: All of the above packages, which I have uploaded, can be downloaded directly using.
