Ignore “cannot find module” error on typescript

由 时间秒杀一切 提交于 2020-12-29 05:14:06
问题 Can the Typescript compiler ignore the cannot find module 'x' error on import expressions such as: //How to tell the compiler that this module does exists import sql = require('sql'); There are multiple npm libraries such as node sql that doesn't have existing typings Is there a way to tell the compiler to ignore this error other than creating a new definition file with the declare module x ... ? 回答1: If you just want to bypass the compiler, you can create a .d.ts file for that module, for

Python importing from parent's child folder

由 允我心安 提交于 2020-12-26 12:17:06
问题 I have a question. I have a directory setup like this: folder/ main.py /stuff/ __init__.py function.py /items/ __init__.py class.py My question is how would I import the class.py into the function.py? This setup is very specific and is unable to be changed. What would I need to put in order for this to work? 回答1: Your current directory structure seems ideal, so long as the application is started via main.py . Python will always automatically add the parent directory of the main script to the

Make Games with Python & Pygame (1)

由 空扰寡人 提交于 2020-12-25 20:05:03
看见这本书很有意思，利用Python和Pygame模块进行游戏开发，边学习边翻译边写心得。 http://download.csdn.net/detail/abclixu123/4582805 这是真本书的下载地址。 第二章介绍Pygame的一些基础知识。开始也是以经典的Hello World开始。所用的开发环境就是安装Python后自带的IDLE。 HelloWorld程序如下： import pygame, sys from pygame.locals import * pygame.init() DISPLAYSURF = pygame.display.set_mode((400,300)) pygame.display.set_caption('Hello World') while True: for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() pygame.display.update() 这个程序运行后就是一个简单的黑色窗口。 对这个程序有几点说明 需要包含Pygame模块，即import pygame 在进行任何具体的Pygame的操作之前，都要进行Pygame的初始化，即pygame.init() DISPLAYSURF = pygame.display
