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。它失败了，关于没有生成文件的轮子的遗留构建错误。
我已经在Docker容器中更新了g ++，以确保这不是问题所在。
我也更新了setuptools和wheel。
我也试过PIP_NO_BINARY=cppyy以确保pipenv没有使用cppyy的预制轮。

最后一行失败了。

预期的结果显然是来自pipenv的“安装成功”。实际的错误消息如下：

编辑：以下实际工作：
RUN pipenv install --clear --system --python=3.6; exit 0
RUN pipenv install --clear --system --python=3.6
第一次安装失败，但第二次安装没有任何麻烦。也许这有帮助。
由于它第二次成功，我最好的猜测是包没有按预期的顺序安装。或者在处理下一个包之前未完全安装。
根据日志文件片段，不清楚尝试的安装顺序是什么。显示的错误消息似乎只是为了cppyy，但它说的是如果b / c失败它无法找到CPyCppyy的鸡蛋，所以相关的错误消息应该来自那个。请注意，禁用轮子和蛋的构建，因为pip在尝试构建之前不会解析依赖关系。这意味着这样的构建会失败，或者如果恰好存在一个旧的安装（更糟糕的话）。
无论如何，订单必须是cppyy-cling，cppyy-backend，CPyCppyy，cppyy。 （这里解释了分裂背后的原因：https://cppyy.readthedocs.io/en/latest/packages.html#package-structure。）每个包都需要在下一个包之前完全安装：cling-config脚本（由cppyy-cling提供）用于传播编译器标志（特别是它传播哪个应该支持C ++标准），因此需要可用。
