conan package

本文档翻译自：https://docs.conan.io/en/latest/reference/commands/development/package.html

$ conan package [-h] [-bf BUILD_FOLDER] [-if INSTALL_FOLDER]
                [-pf PACKAGE_FOLDER] [-sf SOURCE_FOLDER]
                path

调用您本地的conanfile.py的 “package()” 方法。
此命令在用户空间中起作用，它将把工件从–build-folder和–source-folder文件夹复制到–package-folder文件夹。 它不会在本地缓存中创建新程序包，如果要执行此操作，请在”conan build”命令后使用 “conan create” 或 “conan export-pkg”。

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
  -bf BUILD_FOLDER, --build-folder BUILD_FOLDER
                        Directory for the build process. Defaulted to the
                        current directory. A relative path to the current
                        directory can also be specified
  -if INSTALL_FOLDER, --install-folder INSTALL_FOLDER
                        Directory containing the conaninfo.txt and
                        conanbuildinfo.txt files (from previous 'conan
                        install'). Defaulted to --build-folder
  -pf PACKAGE_FOLDER, --package-folder PACKAGE_FOLDER
                        folder to install the package. Defaulted to the
                        '{build_folder}/package' folder. A relative path can
                        be specified (relative to the current directory). Also
                        an absolute path is allowed.
  -sf SOURCE_FOLDER, --source-folder SOURCE_FOLDER
                        Directory containing the sources. Defaulted to the
                        conanfile's directory. A relative path to the current
                        directory can also be specified

package() 方法可能使用来自指定配置文件的设置，选项和环境变量，以及来自conanfile要求中已声明的deps_XXX_info对象的依赖项信息。
运行conan install时，所有这些信息分别自动保存在conaninfo.txt和conanbuildinfo.txt文件中。 这些文件必须位于指定的—build-folder中。

$ conan install . --build-folder=build

Examples
本示例说明 package() 如何在可编辑并内置于用户文件夹而不是本地缓存中的包中工作。

$ conan new hello/0.1 -s
$ conan install . --install-folder=build_x86 -s arch=x86
$ conan build . --build-folder=build_x86
$ conan package . --build-folder=build_x86 --package-folder=package_x86
$ ls package/x86
> conaninfo.txt  conanmanifest.txt  include/  lib/

:::info Note
本地创建的软件包仅供用户使用，不能被其他软件包直接使用，也不能上载到远程存储库。 为了使这些软件包对系统可用，必须将它们放入conan本地缓存中，这可以使用conan export-pkg命令来完成，而不是使用conan package命令：
::: :::info

$ conan new hello/0.1 -s
$ conan install . --install-folder=build_x86 -s arch=x86
$ conan build . --build-folder=build_x86
$ conan export-pkg . hello/0.1@user/stable --build-folder=build_x86 -s arch=x86
