Requirement already satisfied: colorama in c:\users\86134\appdata\local\programs\python\python311\lib\site-packages (from pytest) (0.4.6)

As an AI language model, I don't have access to the current environment and cannot verify the existence of the colorama package. However, based on the message you provided, it seems that the colorama package is already installed and satisfies the requirement for pytest.

Requirement already satisfied: flask in c:\program files\python38\lib\site-packages (2.3.2) Requirement already satisfied: Werkzeug>=2.3.3 in c:\program files\python38\lib\site-packages (from flask) (2.3.4) Requirement already satisfied: Jinja2>=3.1.2 in c:\program files\python38\lib\site-packages (from flask) (3.1.2) Requirement already satisfied: itsdangerous>=2.1.2 in c:\program files\python38\lib\site-packages (from flask) (2.1.2) Requirement already satisfied: click>=8.1.3 in c:\program files\python38\lib\site-packages (from flask) (8.1.3) Requirement already satisfied: blinker>=1.6.2 in c:\program files\python38\lib\site-packages (from flask) (1.6.2) Requirement already satisfied: importlib-metadata>=3.6.0 in c:\program files\python38\lib\site-packages (from flask) (6.6.0) Requirement already satisfied: colorama in c:\program files\python38\lib\site-packages (from click>=8.1.3->flask) (0.4.6) Requirement already satisfied: zipp>=0.5 in c:\program files\python38\lib\site-packages (from importlib-metadata>=3.6.0->flask) (3.15.0) Requirement already satisfied: MarkupSafe>=2.0 in c:\program files\python38\lib\site-packages (from Jinja2>=3.1.2->flask) (2.1.2)

看起来您已经成功安装了 Flask。接下来可以创建一个简单的 Flask 应用程序。您可以在 Python 中创建一个新文件，然后将以下代码复制到该文件中：

from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello():
    return 'Hello, World!'

这个应用程序非常简单，它只有一个路由 '/'，当访问该路由时，它会返回 'Hello, World!'。现在，您可以运行这个应用程序。在命令提示符中输入以下命令：

export FLASK_APP=yourfilename.py
flask run

这会启动 Flask 开发服务器，并在默认情况下监听本地主机的端口 5000。现在您可以在浏览器中访问 `http://localhost:5000/`，应该会看到 'Hello, World!' 的消息。
