Question

我无法让烧瓶在vscode中使用迷你项目和默认设置运行，而无法在仅安装烧瓶的conda环境中运行。无论我尝试什么，烧瓶运行都将启动。转到http://127.0.0.1:5000/将给出以下错误消息。是否从提示符运行都没有关系。以调试方式运行或以任何其他flask -m运行方式运行。

代码：

from flask import Flask
app = Flask(__name__)

@app.route("/")
def home():
    return "Hello, Flask!"


flask run
     * Serving Flask app "app.py"
     * Environment: production
       WARNING: Do not use the development server in a production environment.
       Use a production WSGI server instead.
     * Debug mode: off
     * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

            "type": "python",
            "request": "launch",
            "module": "flask",
            "env": {
                "FLASK_APP": "app.py"
            },
            "args": [
                "run",
                "--no-debugger",
                "--no-reload"
            ],
            "jinja": true
        },

您似乎缺少一些软件包。尝试运行pip3 install -r requirements.txt --ignore-installed，看看是否可行。

此外-确保将启动配置FLASK_APP条目设置为应用程序正在运行的目录。

Python解释器的位置必须包含在PATH环境变量中。
