烧瓶应用程序不工作

Question

在过去的几周里，我花了太多的时间试图让它发挥作用。我的目标是使用烧瓶框架创建一个简单的网络应用程序，但我不断收到错误，几个小时的谷歌搜索和搜索stackoverflow也没有帮助。

我正在学习一个教程，该教程要求我运行：$python3 routes.py

只有我才能得到以下错误：

回溯（最近的最后一次调用）：文件“routes.py”，第1行，从flask导入flask中，呈现\u模板导入错误：没有名为“flask”的模块

好的那么烧瓶没有安装？显然，每个网站都告诉我输入$pip安装烧瓶

警告：在目录“tests”下找不到与“”匹配的文件警告：在目录“docs”下找不到以前包含的文件。pyc警告：在目录“docs”下找不到以前包含的文件。pyo警告：在目录“tests”下找不到以前包含的文件。pyc警告：没有以前包含的文件在目录“tests”下找到了匹配的“.pyo”警告：在目录“examples”下找不到与“.pyc”匹配的以前包含的文件

…雅达雅达雅达。。。

错误：无法创建/库/Python/2.7/site-包/烧瓶：拒绝权限

有人愿意牵着我的手度过难关吗？我应该怎么做才能让事情运转起来？

Answer 1

如果你想使用Python3，你必须为Python3安装flask——你目前只在2.7上安装它。

将-3.0替换为系统上实际安装的版本。

替代：Python3 /usr/bin/pip安装Flask（pip可能安装在其他地方？）

pip：处理多个Python版本？

如何为特定版本的安装模块使用pip？

Answer 2

好吧，首先。烧瓶没有安装，所以我们必须先安装它。

在UNIX中安装stuff（在您的情况下是Mac）时，需要root权限。有很多方法可以将东西作为根运行，最简单的是

sudo YOUR COMMAND HERE

所以如果你想安装烧瓶，你会运行：

sudo pip install flask

然后，打开一个python shell并导入烧瓶，它应该工作正常。

 My-MacBook-Pro:~ user$ python
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import flask
