我想创建一个将 python3.8 作为 python3 的 venv 在 Ubuntu 18.04 上我做了：

> sudo apt install python3.8 python3.8-venv

现在，当我尝试：

> python3.8 -m venv env

The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv   
package using the following command.

    apt-get install python3-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: ['/home/pushp/vizio-backend/env/bin/python3.8', '-Im', 'ensurepip', '--upgrade', '--default-pip']

我的应用程序依赖于 python3.8。我在这里缺少什么？

当我使用 uvicorn 运行我的 FastAPI 服务器时：

uvicorn main:app --host 0.0.0.0 --port 8000 --log-level info

运行服务器后得到的日志：

INFO:     Started server process [405098]
INFO:     Waiting for application startup.
INFO:     Connect to database...
INFO:     Successfully connected to the database!
INFO:     Application startup complete.

INFO:     122.179.31.158:54604 - "GET /api/hello_world?num1=5&num2=10 HTTP/1.1" 200 OK

如何获取时间戳和请求日志记录？喜欢：

INFO:     "2020-07-16:23:34:78" - 122.179.31.158:54604 - "GET /api/hello_world?num1=5&num2=10 HTTP/1.1" 200 OK

some_file.py：

#! /usr/bin/python
print("Hello World!")

在终端：

sudo chown +x some_file.py
chown: invalid user: ‘+x’

我想让文件可执行。
