Lando是一个免费的、开源的、跨平台的、基于Docker的本地开发环境和DevOps工具容器技术,旨在与大多数语言、框架和服务一起使用,为所有开发人员提供了一个简单的方法,可以为他们的项目指定简单或复杂的要求,然后快速开始工作。 ,,以下是搭建和管理Lando本地开发环境的步骤:,1. 安装Docker Desktop for Mac。,2. 打开终端并运行以下命令以下载和安装Lando CLI:,``bash,curl -fsSL https://lando.sh/install.sh | sh,
`,3. 配置您的计算机以允许您在任何位置使用sudo。,4. 使用Lando创建一个新的项目:,
`bash,lando create myproject,
`,5. 进入新创建的项目目录:,
`bash,cd myproject,
`,6. 启动本地开发服务器:,
`bash,lando start,
``
在当今的软件开发领域,高效的开发环境对于提高编程效率和保证代码质量至关重要,本文将为您详细介绍如何搭建和管理一个适用于Lando项目的本地开发环境,帮助您成为一名优秀的评测编程专家。
1、安装Lando
我们需要在计算机上安装Lando,Lando是一个开源的评测框架,可以帮助我们快速构建和运行评测任务,您可以通过以下命令安装Lando:
pip install lando
2、创建项目
安装完成后,我们可以开始创建一个Lando项目,在您的计算机上创建一个新的文件夹,然后在该文件夹中运行以下命令以初始化一个新的Lando项目:
lando init my_project
这将在您的项目文件夹中生成一个基本的项目结构,包括src
、test
和.lando
文件夹,我们需要配置.lando
文件夹以满足我们的开发需求。
3、配置.lando
文件夹
在.lando
文件夹中,我们需要创建一个名为config.toml
的配置文件,以便我们可以根据需要定制开发环境,在config.toml
文件中,我们可以设置各种选项,例如编译器、调试器等,以下是一个简单的配置示例:
[build] compiler = "gcc" debug = true [debugger] type = "lldb"
4、添加依赖库
为了支持我们的评测任务,我们需要在项目中添加相应的依赖库,在my_project/src
文件夹中创建一个名为requirements.txt
的文件,并在其中列出我们的项目所需的所有依赖库及其版本。
numpy==1.21.0 scipy==1.7.1
在.lando
文件夹中的config.toml
文件中添加一个名为dependencies
的选项,以便Lando知道在哪里查找这些依赖库。
[dependencies] path = "src/requirements.txt"
5、编写评测任务代码
现在我们已经准备好开始编写评测任务代码了,在my_project/src
文件夹中创建一个新的Python文件(例如my_evaluator.py
),并编写您的评测任务代码。
