Question

我是python初学者，我在获取一条简单路线的数据时遇到上述错误，并且没有编写任何逻辑，我只是将用户重定向到新模板。

我已经在github上添加了这个项目，并且因为这个原因而切换了分支。.

我能够正确打开主页，但仪表板显示了此问题

错误stactrace在下面

    # List all sites, applications and appPools
dir IIS:\AppPools | ForEach-Object {
    # Site's app pool
    $_.name
    $_.managedRuntimeVersion

Answer 1

我遇到了同样的问题，给定帖子上的所有操作都显示了相同的错误，最后得到了这段代码来更改端口号：

from flask import Flask

app = Flask(__name__)


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


if __name__ == "__main__":
    import os

    HOST = os.environ.get('SERVER_HOST', 'localhost')
    try:
        PORT = int(os.environ.get('SERVER_PORT', '5555'))
    except ValueError:
        PORT = 5555
    app.run(HOST, PORT)

我的端口号以前默认设置为5000，现在我将其更改为5555，您可以将其更改为任何端口号

Answer 2

我也遇到了这个问题，参考楼上的方法，将端口号修改为5555，问题就解决了。这个问题困扰了我一天
