PyBuilder不會安裝Flask？

Question

所以我試圖爲我的燒瓶應用程序安裝pybuilder，並且出於某種原因，它不安裝依賴項？它顯示了這個當我運行 'PYB install_dependencies'

PyBuilder version 0.11.10 
Build started at 2017-07-17 11:57:23 
------------------------------------------------------------ 
[INFO] Building flask-example version 0.1.2 
[INFO] Executing build in /home/aalred/flask-example 
[INFO] Going to execute task install_dependencies 
[INFO] Installing all dependencies 
[INFO] Processing batch dependency 'coverage' 
[INFO] Processing batch dependency 'pyassert' 
[INFO] Processing batch dependency 'pyfix' 
[INFO] Processing batch dependency 'flask' 
------------------------------------------------------------ 
BUILD SUCCESSFUL 
------------------------------------------------------------ 

但後來當我做了命令：

python hello.py 

我收到以下錯誤：

from flask import Flask, render_template 
ImportError: No module named flask 

可有人請解釋什麼正在進行？這讓我很困惑，我似乎無法找到一個直截了當的答案。

這是我build.py是否有幫助太：

from pybuilder.core import init, use_plugin 

use_plugin("python.core") 
use_plugin("python.install_dependencies") 
#use_plugin("python.unittest") 

default_task = ['install_dependencies', 'publish'] 

@init 
def initialize(project): 
    project.build_depends_on('pyfix') 
    project.build_depends_on('pyassert') 
    project.depends_on('flask') 
    project.depends_on('flask-mysql') 

Answer 1

一些細緻的挖掘之後，我發現我反覆運行build.py有

project.depends_on('flask') 

註釋掉。傻我！
