1 安装conan

1.1 安装依赖软件

1.1.1 python安装

pip需要依赖python (>= 3.9)，我本地安装的3.10.10版本的python。
Python 软件包：
python软件包直接去官网下载比较慢，在安装时选中安装路径添加到环境变量（Add Python to PATH）的选项，其他的默认安装即可。
python的官方网站：
https://www.python.org/downloads/windows/

1.1.2 git bash安装

可以在http://www.git-scm.com/download/下载对应的windows版本的git去安装使用。

1.1.3 安装Visual Studio Community 2019

打开Microsoft Store中搜索Visual Studio Community 2019，选择安装。
如果选择Visual Studio Community 2022请参考该篇博文：windows环境下VSCode配置C++教程（使用msvc编译器），需要注意的是Visual Studio Community 2022对应的MSVC是17而不是2019版的16，如果使用msvc16去编译需要对应的适配一个msvc17的profile配置文件。

1.1.3.1 选择安装的组件

1.1.3.2 选择要支持的工具以及对应的SDK

1.1.4 vscode安装

可以直接在vscode官网下载Download Visual Studio Code - Mac, Linux, Windows，需要选择System Installer软件包安装。

1.2 安装1.55.0版本的conan
conan在windows上最新的版本是2.xx的，conan的1.xx版本和2.xx版本的差异非常大，我们在开发时目前需要的是conan 1.xx版本去做代码库管理工作，在安装时需要制定要安装的1.xx的conan版本号。

pip install conan=1.55

1.3 验证conan功能

直接在windows的powershell视图执行conan命令即可，执行之后会显示conan的帮助信息。
