$ conan source [-h] [-sf SOURCE_FOLDER] [-if INSTALL_FOLDER] path

调用您本地的conanfile.py的“ source（）”方法。
通常下载并解压缩软件包源。

positional arguments:
  path                  Path to a folder containing a conanfile.py or to a
                        recipe file e.g., my_folder/conanfile.py
optional arguments:
  -h, --help            show this help message and exit
  -sf SOURCE_FOLDER, --source-folder SOURCE_FOLDER
                        Destination directory. Defaulted to current directory
  -if INSTALL_FOLDER, --install-folder INSTALL_FOLDER
                        Directory containing the conaninfo.txt and
                        conanbuildinfo.txt files (from previous 'conan
                        install'). Defaulted to --build-folder Optional,
                        source method will run without the information
                        retrieved from the conaninfo.txt and
                        conanbuildinfo.txt, only required when using
                        conditional source() based on settings, options,
                        env_info and user_info

source（）方法可能会使用（可选）指定配置文件中的设置，选项和环境变量以及conanfile要求中已声明的deps_XXX_info对象的依赖项信息。。
所有这些信息都将运行柯南install命令自动在conaninfo.txt和conanbuildinfo.txt文件保存分别。这些文件必须位于指定—install文件夹。

Examples:
调用本地配方的source方法：在用户空间中，该命令将在当前目录的src文件夹中执行local conanfile.py source（）方法。

$ conan new lib/1.0@conan/stable
$ conan source . --source-folder mysrc

如果你需要设置/选项或要求的任何信息，首先进行的安装：

$ conan install . --install-folder mybuild
$ conan source . --source-folder mysrc --install-folder mybuild
