pythonldap操作教程（Pythonflask学习-环境搭建遇到的坑）

目的简单,就是为了做一个学习类论坛网站,最初想法是用fastapi写,但fastapi 网上资料太少,会用了flask 后再用fastapi

coding,环境搭建

安装与配置

1. python 3.9

1. vscode安装

安装省略

2. 虚拟环境安装进入你要创建的文件相对位置进行创建,也可以使用相对位置 /xxx/xxx/FlaskWeb

python -m venv FlaskWeb

3. 处理问题-因为系统权限问题,导致 vscode terminal 无法进入虚拟环境, 使用 管理员权限运行 cmd, 是可以进入虚拟环境的.

尝试新的跨平台 PowerShell https://aka.ms/pscore6 PS E:\PythonCoding> & e:/PythonCoding/FlaskWeb/Scripts/Activate.ps1 & : 无法加载文件 E:\PythonCoding\FlaskWeb\Scripts\Activate.ps1，因为在此系统上禁止运行脚本。有关详细信息，请参阅 https:/go.microsoft.com/fwlink/?LinkID=135170 中的 about_Execution_Policies。 所在位置 行:1 字符: 3 & e:/PythonCoding/FlaskWeb/Scripts/Activate.ps1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ CategoryInfo : SecurityError: (:) []，PSSecurityException FullyQualifiedErrorId : UnauthorizedAccess PS E:\PythonCoding> & e:/PythonCoding/FlaskWeb/Scripts/python.exe e:/PythonCoding/flaskWeb/app.py PS E:\PythonCoding> & : 无法加载文件 E:\PythonCoding\FlaskWeb\Scripts\Activate.ps1，因为在此系统上禁止运行脚本。有关详细信息，请参

• 解决

1. 管理员身份运行powershell 输入 ： set-executionpolicy remotesigned，接下来输入“y”表示执行 - 如何不知道怎么打开,请查看这篇文章　在Windows 10下打开带管理员权限的PowerShell的5种方式 ＞　https://blog.csdn.net/kenzo2017/article/details/79518540

运行第一个页面 hello world

比较坑,第一个你好!就这么难,运行几次都没出来,原因是端口被占用,而且输入2次都占用,奇葩.

• 更改端口为 9200才运行起来

from flask import Flask app = Flask(__name__) @app.route('/') def hello_world(): return 'Hello World' if __name__ == '__main__': app.run('127.0.0.1', 9200, debug=True)

最后吐槽一下, charm 这个工具,罢工了,挺无语的,只能用vscode 了.

很尴尬，临时得换工具了，这pycharm 罢工了
