我正在尝试构建开放能量建模框架 (oemof) PyPi 包的 conda 包，如相应手册中所述。oemof 包有Pyomo包作为我使用合适的配方预先安装的要求。

我的问题是我现在在构建过程中遇到错误：

 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

我的错误是什么？如何按照 conda 手册中的说明构建我的包？

提前致谢！

下面你可以看到我到目前为止所经历的步骤：

cord@crd-Laptop:~/.anaconda3/bin$ ./conda skeleton pypi oemof

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

我相信这里的问题是conda build在构建时创建了一个全新的 conda 环境，并且它将在该环境中安装所有包依赖项，包括 pyomo。它通过在频道中查找它们而不是通过根目录中当前安装的软件包来安装它们。在此示例中，您将 pyomo 作为软件包安装，但它不是来自您自己安装的频道列表中的频道。因此，在搜索您的 conda 频道时找不到 pyomo 包。但是，如果我们向 conda build 正在查看的-c具有 pyomo 的列表（通过标志）添加一个通道，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。
