conda build: ResolvePackageNotFound 取决于机器

Question

我正在构建一个自定义 conda 包，它依赖于来自自定义频道的其他四个包。 当我尝试conda build . 在机器 A 上，这些包被报告为不可满足（见下文）。 在机器 B 上，具有相同的提交， conda build工作。

我将工作构建环境从机器 B 克隆到机器 A，但没有成功。

自定义频道位于网络目录中。 从中安装有问题的软件包可以在两台机器上运行。 出于某种原因，在机器 A 上conda build似乎无法访问。

（底部） conda build在机器 A 上的错误消息：

编辑：我发现如果我使用conda build -c file:////custom/channel . . 我仍然不明白为什么这应该是必要的，因为通道显示在conda config 、 conda env export和conda info中。 我尝试使用conda config --remove channels file:////custom/channel删除它并使用conda config --add channels file:////custom/channel channel 重新添加它，但是简单的conda build . 仍然失败。

Answer 1

我发现了问题所在。 这与我雇主的网络设置有关。 我们通常使用 VPN，在该 VPN 中，用户主目录（即$HOME环境变量）设置为网络驱动器H: 。 前几天，我无法连接到 VPN。 这意味着 a) 用户主目录是标准C:\Users\<Username>并且 b) 我无法连接到自定义 conda 通道。 事实上，我无法用 conda 做任何事情，因为它总是会出错，因为该通道无法访问。 所以我通过conda config删除了它，它从C:\Users\<Username>\.condarc了。 然后我记得重新启动修复了 VPN 问题并重新启动。 当计算机备份并在 VPN 中时，我不确定我是否真的删除了通道（或者我是否在开始之前记住了解决方案），所以我通过conda config进行了检查。 只是现在，它引用了H:\.condarc ，它仍然有通道。 所以我只是继续正常工作，期待 conda build 仍然有效。

但是，结果是conda install仍然可以访问自定义通道的设置（它必须使用$HOME环境变量来查找.condarc ）而 conda conda build不能（它必须直接使用C:\users\<Username> ）。
