PyBuilder不会安装水瓶吗？

Question

因此，我试图为我的烧瓶应用程序安装pybuilder，而出于某种原因，它不安装依赖项？它在运行'pyb install_dependencies‘时显示了这一点。

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
------------------------------------------------------------

但当我执行命令时：

python hello.py

我得到以下错误：

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

有人能解释一下发生了什么事吗？这让我很困惑，我似乎找不到一个直截了当的答案。

这是我的build.py，如果这也有帮助的话：

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

经过仔细的挖掘，我发现我反复运行的build.py

project.depends_on('flask')

评论掉了。我真傻!
