问题描述
我不是柯南专家,所以也许有一个明显的解决方案。但这不是微不足道的,因为我为此苦苦挣扎了一段时间并且找不到解决方案。
我们的项目需要镶木地板,我们通过像这样的柯南箭头包 conanfile.txt 包含它:
[requires]
arrow/2.0.0
[generators]
cmake
[options]
spdlog:=gcc
arrow:shared=False
arrow:parquet=True
arrow:fPIC=False
arrow:with_re2=False
arrow:with_protobuf=False
arrow:with_openssl=False
arrow:with_gflags=False
arrow:with_glog=False
arrow:with_grpc=False
arrow:with_utf8proc=False
arrow:with_zstd=False
arrow:with_bz2=False
(我删除了所有其他包,但没有那么多)
问题出在我们的 CI 上,我们得到了错误:

正确表明在 CI 上我们使用带有 conan 1.32.1 的容器,这似乎与想要 >= 1.33.0 的 openssl/1.1.1j 冲突。
我觉得这很烦人,因为我们明确不想要也不需要 openssl,我们将其关闭以获取箭头(见上文)。
当我运行 conan info .
时,我可以看到:

看来,openssl 被引入的原因是因为 thrift 和 libevent。
鉴于我们无法更改 CI 容器,因为这样我们基本上会放弃对我们需要支持的平台的支持,因此这里有什么解决方案?
-
为什么 openssl 首先依赖于 conan 版本?我们不能修复或解决这个问题吗?
-
我们能否以某种方式影响箭头的依赖树以避免对 openssl 的任何引用?例如。提供没有 openssl 的 thrift/libevent 的专用版本(如果这甚至可能的话)?
-
还有其他选择吗?
(作为脚注,我们使用的容器和系统都不是非常过时,所以我相信这个问题很容易影响很多用户。我搜索了一段时间没有找到任何解决方案。)
解决方法
明显的建议:Update柯南到最新版本 (1.35.1)。
pip install -U conan
柯南中心索引(所有官方)中的包不会被任何旧版本阻止,实际上它是强制性的,必须使用最新的柯南版本进行测试。 Conan Center Index 假设您也运行最新的 Conan 客户端版本:
为什么 openssl 首先依赖于柯南版本?我们不能修复或解决这个问题吗?
每个新版本都会引入新的柯南功能。你不能简单地改变食谱,因为你正在消费它们。即使您下载了配方并删除了该检查,它也会失败,因为您的柯南客户端版本不支持该配方中的某些方法/功能。
我们能否以某种方式影响箭头的依赖树以避免对 openssl 的任何引用?例如。提供没有 openssl 的 thrift/libevent 的专用版本(如果这甚至可能的话)?
可以,但不推荐。您可以在 conanfile.txt 中声明箭头使用的其他包版本,它会强制柯南使用您的版本。
还有其他选择吗?
是的,不要尝试变通办法,做正确的事,更新您的客户端版本。
