Question

试图利用Conda的build功能安装不在conda存储库中的软件包。我已经下载了想要的软件包的源文件。在同一级别上，我为 conda食谱创建了一个文件夹，其中包含meta.yaml设置source: path: ../<package-name>。因此，查找一个目录以查找源文件。这行得通。

当构建尝试测试导入包时，问题最终会发生。它说没有找到 x模块，但是我是从一个conda环境中调用conda build的，在conda环境中安装了缺少的软件包，如conda list所示。

我如何从conda build的环境中进行这些测试？

使用conda build时如何设置环境？

Conda Build文档中充斥着 environment 这个单词，但大部分指的是environmental variables而不是conda environments

我仍在解决类似的问题，但我想我至少可以为您提供帮助。（或者遇到相同问题的人）。

conda构建末尾的测试步骤使用的是全新环境-仅包含您的软件包及其特定要求（如recipe/meta.yaml中所述。（注意，您未显示{{ 1}}，这是解决此问题的关键）

如果您的包裹需要它，请在meta.yaml中放入以下内容：

meta.yaml

如果您的软件包确实不需要它，但是测试代码（例如单元测试）需要运行它，请使用以下部分：

requirements:
  host:
    - python
    - pip
  run:
    - python
    - requests  # here

这些软件包将使用test: requires: - nose # e.g. some test runners - requests # extra deps for test而非conda安装。

如何从pip获取信息，或以任意方式修改测试环境？我还在想这个...

使用`conda build`时如何设置环境？
