如何修复自定义conda包的conda UnsatisfiableError？

Question

我正在尝试打包我的python代码，以便在Anaconda云上发布。文件夹结构如下所示：

命令用于构建包(haasad是pypardiso包的通道的名称)：conda build conda-recipe -c haasad构建成功，我已经将它上传到这里：https://anaconda.org/monomonedula/sten

但是，在安装了像这样的本地构建：conda install sten --use-local -c haasad和上传到云conda install -c monomonedula sten -c haasad的构建之后，我遇到了几个问题。

• 当使用python3.7时，我无法导入我的包，即使它是在conda list中列出的(我已经双重检查了所有内容，我使用的是正确的解释器)。
• 当使用python3.8时，我可以导入并使用它，但是由于未知的原因，我无法安装stellargraph。错误信息：

我在这里遗漏了什么，我如何正确地包装它？

Answer 1

问题在您的meta.yaml文件中。根据一个Anaconda博客文章

允许用户在conda包中分发文档、数据集和源代码。

和

Noarch包减少了在不同架构和Python版本上构建多个不同的纯Python包的开销，方法是在安装时整理平台和Python版本特定的差异。

因为您想要分发一个纯python包，所以应该使用noarch: python。另外，您不需要在python和build中设置run版本。我在下面包括了一个更新的meta.yaml。它还包括它中的构建脚本，因此您不再需要build.sh和build.bat文件。它还将许可证部分修复到conda将接受的内容(仍然是Apache2.0)。

package:
  name: sten
  version: "0.1.0"

source:
  path: ..

build:
  number: 0
  noarch: python
  script: {{ PYTHON }} setup.py install

requirements:
  build:
    - python
    - setuptools
  run:
    - python
    - pypardiso >=0.2.2
    - numpy >=1.18.1
    - networkx >=2.4
    - scipy >=1.4.1
    - markdown

test:
  imports:
    - sten.embedding

about:
  home: https://github.com/monomonedula/simple-graph-embedding
  license: Apache-2.0
  license_family: Apache
  license_file: LICENSE.txt
  summary: Simple deterministic algorithm for generating graph nodes topological embeddings.

下面是使用上面的meta.yaml文件构建和安装这个包的步骤：

git clone https://github.com/monomonedula/simple-graph-embedding
cd simple-graph-embedding/
git checkout 'refactor&cleanup'
# Replace contents of `meta.yaml`
rm conda-recipe/build.sh conda-recipe/build.bat
conda create --yes -n testing python=3.7 conda-build conda-verify
conda activate testing
conda-build --channel haasad .

下面是我在3.7环境中安装软件包时所做的工作。您将找到指向sten-0.1.0-py_0.tar.bz2日志输出底部的完整路径。

conda install -n testing /home/jakub/miniconda3/envs/testing/conda-bld/noarch/sten-0.1.0-py_0.tar.bz2
conda activate testing
$CONDA_PREFIX/bin/python -c "import sten"

我还在python3.8环境中测试了安装。

conda create --yes -n testing3.8 python=3.8
conda install -n testing3.8 /home/jakub/miniconda3/envs/testing/conda-bld/noarch/sten-0.1.0-py_0.tar.bz2
conda activate testing3.8
$CONDA_PREFIX/bin/python -c "import sten"

conda install --use-local sten不是为我工作的
