通过 Conan 安装仅标头包时出错

Error installing header only package via conan

本文关键字：包时 出错 Conan 安装 通过      更新时间：2023-10-16

我有一个使用 CMake 构建的内部仅标头C++库。我按照 conan 关于如何打包仅标头库的说明进行操作，最终得到了以下 conanfile.py：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""
Conan file for KVAPI.
https://docs.conan.io/en/latest/howtos/header_only.html
"""
from conans import ConanFile, CMake

class KVAPIConan(ConanFile):
    name = "kvapi"
    version = "0.1.0.0"
    description = "Kiwi API library"
    exports_sources = "include/*"
    topics = ("kv", "kvapi", "C++")
    no_copy_source = True
    def package(self):
        self.copy("*.hpp")
    def package_id(self):
        self.info.header_only()

我这样创建包：

> conan create . kvapi/0.1.0.0@kiwi/testing
> conan upload kvapi* -r genetec

并因此安装它：

> conan install kvapi/0.1.0.0@kiwi/testing

这会导致错误：

对于仅标头库，这是否是预期的？

上传 Conan 包时，当你要上传二进制包时，也需要明确。

该命令conan upload kvapi* -r genetec仅上传配方，而不上传创建的包。要上传配方包和包含这些标头的二进制包，您需要添加参数--all

conan upload kvapi* -r genetec --all
