Install pip as described here: How do I install pip on Windows?

按照此处所述安装 pip：如何在 Windows 上安装 pip？

Then do

然后做

pip install flask

That installation tutorial is a bit misleading, it refers to actually running it in a production environment.

那个安装教程有点误导，它指的是实际在生产环境中运行它。

On Windows, installation of easy_install is a little bit trickier, but still quite easy. The easiest way to do it is to download the distribute_setup.py file and run it. The easiest way to run the file is to open your downloads folder and double-click on the file.

在 Windows 上，easy_install 的安装有点棘手，但仍然很容易。最简单的方法是下载distribute_setup.py 文件并运行它。运行该文件的最简单方法是打开您的下载文件夹并双击该文件。

Next, add the easy_install command and other Python scripts to the command search path, by adding your Python installation's Scripts folder to the PATH environment variable. To do that, right-click on the “Computer” icon on the Desktop or in the Start menu, and choose “Properties”. Then click on “Advanced System settings” (in Windows XP, click on the “Advanced” tab instead). Then click on the “Environment variables” button. Finally, double-click on the “Path” variable in the “System variables” section, and add the path of your Python interpreter's Scripts folder. Be sure to delimit it from existing values with a semicolon. Assuming you are using Python 2.7 on the default path, add the following value:

接下来，通过将 Python 安装的 Scripts 文件夹添加到 PATH 环境变量，将 easy_install 命令和其他 Python 脚本添加到命令搜索路径。为此，请右键单击桌面或开始菜单中的“计算机”图标，然后选择“属性”。然后单击“高级系统设置”（在 Windows XP 中，改为单击“高级”选项卡）。然后单击“环境变量”按钮。最后，双击“系统变量”部分中的“路径”变量，并添加 Python 解释器的 Scripts 文件夹的路径。请务必使用分号将其与现有值分隔开。假设您在默认路径上使用 Python 2.7，请添加以下值：

;C:\Python27\Scripts And you are done! To check that it worked, open the Command Prompt and execute easy_install. If you have User Account Control enabled on Windows Vista or Windows 7, it should prompt you for administrator privileges.

;C:\Python27\Scripts 大功告成！要检查它是否有效，请打开命令提示符并执行 easy_install。如果您在 Windows Vista 或 Windows 7 上启用了用户帐户控制，它应该会提示您输入管理员权限。

Now that you have easy_install, you can use it to install pip:

现在你有了 easy_install，你可以用它来安装 pip：

easy_install pip

easy_install pip

我有 Windows 10 和 pythonv3.5。@uku 答案是正确的。但是，我面临的问题是要添加到环境变量中的 python 脚本在哪里。所以我发现我们需要添加

C:\Users\\AppData\Local\Programs\Python\Python35\Scripts

C:\Users\\AppData\Local\Programs\Python\Python35\Scripts

above location as environment variable. If it still doesnot work search for python in C Drive then find out script locations.

以上位置作为环境变量。如果它仍然不起作用在 C 驱动器中搜索 python 然后找出脚本位置。

First: I assumed you already have Python 2.7or 3.4installed.

首先：我假设您已经安装了Python 2.7或 3.4。

1: In the Control Panel, open the System option (alternately, you can right-click on My Computer and select Properties). Select the “Advanced system settings” link.

1：在控制面板中，打开系统选项（或者，您可以右键单击我的电脑并选择属性）。选择“高级系统设置”链接。

1. In the System Properties dialog, click “Environment Variables”.

2. In the Environment Variables dialog, click the New button underneath the “System variables” section.

3. if someone is there that above is not working, then kindly append to your PATH with the C:\Python27 then it should surely work. C:\Python27\Scripts

4. Run this command (Windows cmd terminal): pip install virtualenv

5. If you already have pip, you can upgrade them by running:

   pip install --upgrade pip setuptools

6. Create your project. Then, run virtualenv flask

2. 在“系统属性”对话框中，单击“环境变量”。

3. 在“环境变量”对话框中，单击“系统变量”部分下方的“新建”按钮。

4. 如果有人在那里上面不起作用，那么请将 C:\Python27 附加到您的 PATH 中，那么它肯定可以工作。C:\Python27\Scripts

5. 运行此命令（Windows cmd 终端）：pip install virtualenv

6. 如果你已经有 pip，你可以通过运行来升级它们：

   pip install --upgrade pip setuptools

7. 创建您的项目。然后，运行virtualenv 烧瓶

Follow as in the url

按照网址

This is how i do : 1) create an app.py in Sublime Text or Pycharm, or whatever the ide, and in that app.py have this code

这就是我的做法：1）在 Sublime Text 或 Pycharm 或任何 ide 中创建一个 app.py，并在该 app.py 中有此代码

from flask import Flask

app = Flask(__name__)

@app.route('/')
def helloWorld():
    return'<h1>Hello!</h1>' 

This is a very basic program to printout a hello , to test flask is working.I would advise to create app.py in a new folder, then locate where the folder is on command prompt enter image description heretype in these line of codes on command prompt

这是一个非常基本的程序，用于打印 hello ，以测试烧瓶是否正常工作。我建议在新文件夹中创建 app.py，然后在命令提示符下找到该文件夹​​所在的位置在 此处输入图像描述在这些代码行中键入命令提示符

>py -m venv env
>env\Scripts\activate
>pip install flask

Then

然后

>set FLASK_APP=app.py
>flask run

Then press enter all will work
The name of my file is app.py, give the relevant name as per your file in code line

然后按回车所有将工作
我的文件的名称是app.py，在代码行中根据您的文件给出相关名称

set FLASK_APP=app.py

Also if your python path is not set, in windows python is in AppData folder its hidden, so first have to view it and set the correct path under environment variables. This is how you reach environment variables
Control panel ->> system and security ->> system ->> advanced system setting Then in system properties you get environment variables

另外，如果你的python路径没有设置，在windows中python隐藏在AppData文件夹中，所以首先必须查看它并在环境变量下设置正确的路径。这是您访问环境变量的方式
控制面板 ->> 系统和安全 ->> 系统 ->> 高级系统设置 然后在系统属性中您可以获得环境变量
