使用 TravisCI 在 Anaconda 上部署 Python 包

Question

我正在尝试使用 TravisCI 在 Anaconda 上部署我的 Python 包。我已经设置了 PyPi 部署，运行良好。这是travis.yml文件的相关部分：

deploy:
  provider: pypi
  username: "__token__"
  password:
    secure: ......
  on:
    tags: true
  distributions: "sdist bdist_wheel"
  skip_existing: true

after_deploy:
  - conda install conda-build
  - conda install anaconda-client
  - bash .ci/conda_upload.sh

错误发生在.ci/conda_upload.sh。这里是conda_upload.sh：

USER=myusername

mkdir ~/conda-bld
conda config --set anaconda_upload no
export CONDA_BLD_PATH=~/conda-bld
ls -l
conda build .

find $CONDA_BLD_PATH/ -name *.tar.bz2 | while read file
do
    echo $file
    anaconda -t $CONDA_UPLOAD_TOKEN upload -u $USER $file --force
done

我收到的错误消息发生在conda build .，它找不到setup.py 文件。但是之前的ls -l 调用清楚地表明那里有一个setup.py 文件：

...
-rw-rw-r-- 1 travis travis     1190 Aug 15 09:42 setup.py
...

我也加入了

build:
  script_env:
   - CONDA_BLD_PATH

在meta.yaml 文件中。

这是我在 Travis 上获得的完整输出：

问题似乎是环境位置设置为

但我不知道如何解决这个问题。我对 linux 环境和 shell 脚本很陌生，如果有人可以帮助我，我将不胜感激。

编辑： meta.yaml的内容：

{% set name = "pysprint" %}
{% set version = "0.12.1" %}

package:
  name: "{{ name|lower }}"
  version: "{{ version }}"

source:
  url: "https://pypi.io/packages/source/{{ name[0] }}/{{ name }}/{{ name }}-{{ version }}.tar.gz"
  sha256: 5fee159c59c81fd31957e23bbd292bcfc1c947583f27eda7f4215594ec898ddd

build:
  script_env:
   - CONDA_BLD_PATH

requirements:
  host:
    - matplotlib
    - numpy >=1.16.6
    - pandas
    - pip
    - python
    - scipy

test:
  imports:
    - pysprint

Answer 1

事实证明，deploy 部分以某种方式弄乱了 conda 部署。我将 after_deploy 部分更改为 before_deploy 并且它可以工作。

before_deploy:
  - conda install conda-build
  - conda install anaconda-client
  - bash .ci/conda_upload.sh

deploy:
  provider: pypi
  username: "__token__"
  password:
    secure: ......
  on:
    tags: true
  distributions: "sdist bdist_wheel"
  skip_existing: true

但是我根本不清楚是什么导致了这个问题。
