Anaconda：从 PyPi 包构建时出错 ( "Package XY missing in current linux-64 channels" )

Question

我正在尝试构建开放能源建模框架（oemof）PyPi包的conda包，如各自手册中所述。oemof软件包有Pyomo软件包，这是我使用合适的配方提前安装的。

我的问题是，我现在在构建过程中遇到了一个错误：

 Package missing in current linux-64 channels: 
 - pyomo >=4.2.0

我安装的Pyomo版本似乎高于4.2:

cord@crd-Laptop:~/.anaconda3/bin$ ./conda update pyomo
pyomo                     4.2.10784               py35_10    cachemeorg

我在这里犯了什么错误？如何按照conda手册中的描述构建我的包？

提前感谢！

下面你可以看到我迄今为止所经历的步骤：

Answer 1

对于您的构建步骤，请尝试conda build -c cachemeorg oemof。

我认为这里的问题是conda build在构建时创建了一个全新的conda环境，它将在该环境中安装所有包依赖项，包括pyomo。它通过在通道中查找它们来安装它们，而不是通过根目录中当前安装的软件包来而。在这个例子中，你安装了pyomo作为一个包，但它不是来自你自己安装的频道列表中的频道。因此，在搜索您的conda频道时，它无法找到pyomo包。但是，如果我们将一个具有pyomo的通道添加到conda-build正在查看的列表中（通过-c标志），那么它应该可以工作。看起来cachemeorg有这个包，因此上面的命令应该可以工作。
