Question

我正在尝试构建open energy modelling framework (oemof) PyPi package的conda包，如相应manual中所述。 oemof包具有Pyomo包作为要求，我使用合适的recipe预先安装。

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手册中的描述构建我的包？

提前致谢！

下面你可以看到我到目前为止所经历的步骤：

对于您的构建步骤，请尝试double price; int region; string p; Console.Write("Enter the total price of items : "); price = Convert.ToDouble(Console.ReadLine()); Console.WriteLine("Select the your region."); Console.WriteLine("1 : Pakistan"); Console.WriteLine("2 : UK"); Console.WriteLine("3 : Cortia"); p = Console.ReadLine(); if (!int.TryParse(p, out region)) { //error handle. } else { //at this point, the region value already has the value of p; }。

我认为这里的问题是conda build -c cachemeorg oemof在构建时会创建一个全新的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，并通过您当前安装的根目录中的 not 来安装它们。在此示例中，您已将pyomo作为程序包安装，但在您自己安装时，它并非来自频道列表中的频道。因此，在搜索conda频道时无法找到pyomo包。但是如果我们在列表中添加一个conda build正在查看的频道（通过conda build标志），那么它应该可以工作。看起来cachemeorg有这个package，因此上面的命令应该可以工作。

Anaconda：从PyPi包构建时出错（“当前linux-64通道中缺少包XY”）
