python - Trouble with attribute 'cli' in a fresh Flask install -

this question has answer here:

• can't run example code referenced in flask docs 3 answers

to run flask examples off repo, clone latest stable, create virtual environment, activate it, pip install flask, , try run flaskr.py. following script goes through sequence.

#!/bin/bash  newroot=${home}/flask mkdir $newroot git clone https://github.com/mitsuhiko/flask.git $newroot/repo virtualenv $newroot/venv  source $newroot/venv/bin/activate pip install flask cd $newroot/repo/examples/flaskr/ python flaskr.py 

the last line fails with

traceback (most recent call last):   file "flaskr.py", line 48, in <module>     @app.cli.command('initdb') attributeerror: 'flask' object has no attribute 'cli' 

what missing?

in context not understand: if not run "pip install flask", get

traceback (most recent call last):   file "flaskr.py", line 15, in <module>     flask import flask, request, session, g, redirect, url_for, abort, \ importerror: no module named flask 

if do, earlier error. hence appears "pip install flask" did indeed install flask, don't see flask (not symlink) in newly created ${home}/flask/venv. flask installed?

python 2.7.10 (from macports); pip 1.5.6; os x 10.9.5

app.cli feature in v1.0 branch of flask, not in main 0.10 branch stable branch default pip. either install v1.0 pip, or delete part of code.
