cppyy安装失败
cppyy fails to install
我正在尝试使用 Python 3.6 环境在 Ubuntu 18.04 docker 容器中安装 cppyy。它在本地 (K)ubuntu 18.04 安装上运行良好。它失败并出现有关未生成文件的 wheel 的遗留构建错误。
我已经更新了 Docker 容器中的 g++ 以确保这不是问题所在。
我也更新了 setuptools 和 wheel。
我还尝试 PIP_NO_BINARY=cppyy 确保 pipenv 没有使用 cppyy 的预制轮。

第一次安装失败，但第二次安装成功，没有任何问题。也许这有帮助。
因为它第二次成功了，我最好的猜测是软件包没有按照预期的顺序安装。或者在处理下一个包之前没有完全安装。
根据日志文件片段，尚不清楚尝试的安装顺序是什么。显示的错误消息似乎仅适用于 cppyy，但它只是说如果失败 b/c 它无法找到 CPyCppyy 的鸡蛋，因此相关的错误消息应该来自那个。请注意，wheels 和 eggs 的构建被禁用，因为 pip 在尝试构建它们之前不会解析依赖关系。这意味着这样的构建要么会失败，要么会使用旧的安装（如果碰巧有的话）（这更糟）。
无论如何，顺序必须是cppyy-cling，cppyy-backend，CPyCppyy，cppyy。 （这里解释了拆分背后的原因：https://cppyy.readthedocs.io/en/latest/packages.html#package-structure。）每个包都需要在下一个包继续之前完全安装：cling-config 脚本（由 cppyy-cling 提供）用于传播编译器标志（在特别是它传播了应该支持的 C++ 标准），因此需要可用。
