“没有名为 bs4(BeautifulSoup) Azure 的模块”

Question

我对 Azure 很陌生。我在将我的 Web 应用程序部署到 azure 时遇到问题。以下是我部署时的日志。

Beautifulsoup 最初似乎已安装，但当我提出请求时，它会引发错误。我也无法导入其他流行的库。任何帮助表示赞赏:)

Answer 1

您最好提供更多详细信息，例如 requirements.txt 以及您正在使用的操作系统。

我写了一个包含 Beautifulsoup4 的简单代码（我的环境是 windows 10），它可以很好地工作。我认为您可以将它用于测试目的，以确保 Beautifulsoup4 是否有效。

大部分步骤都遵循这个article。

步骤如下：

1.在 git bash 中： 先执行git clone https://github.com/Azure-Samples/python-docs-hello-world,

然后执行cd python-docs-hello-world

2.修改application.py文件，添加Beautifulsoup4，代码如下：

  from flask import Flask
  from bs4 import BeautifulSoup

  app = Flask(__name__)

  @app.route("/")
  def hello():
      soup = BeautifulSoup("<p>it is a bs4 testing</p>")
      return soup.prettify()

3.修改requirements.txt，添加Beautifulsoup4：

click==6.7
Flask==1.0.2
itsdangerous==0.24
Jinja2==2.10
MarkupSafe==1.0
Werkzeug==0.14.1
beautifulsoup4==4.6.3

4.在git bash中，一一执行以下命令：

py -3 -m venv venv
venv/scripts/activate
pip install -r requirements.txt
FLASK_APP=application.py flask run

打开网络浏览器，然后导航到http://localhost:5000/ 的示例应用程序。

这是为了确保它在本地可以正常工作。

5.然后只需按照article 创建部署凭据/资源组/服务计划/Web 应用程序

6.如果没有问题，在 git bash 中，将代码推送到 azure：

git remote add azure <deploymentLocalGitUrl-from-create-step>

然后git push azure master，输出如下：

7.浏览到 http://.azurewebsites.net 之类的网站，bs4 运行良好：
