我正在使用 conda 构建 python 包，但无法弄清楚它是如何工作的。我试图从 github 源构建一个包，我的 meta.yaml 看起来像这样
{% 设置版本 = "0.5.0" %}
package:
name: bsdiff4
version: {{ version }}
build:
noarch: python
number: 0
source:
git_url: https://github.com/ilanschnell/bsdiff4.git
git_rev: master
requirements:
host:
- python >=3.8
- conda >=4.10
- conda-build
- anaconda-client
run:
- python >=3.8
- matplotlib >=3.3.2
- numpy >=1.18
- pandas >=1.1.2
about:
license: GNU General Public License (GPL)
summary: 'A package for testing the conda build mechanisms'
当我运行“conda-build bsdiff4 --croot conda-build”时，我收到警告“找不到用于输出的文件或脚本”，我不明白为什么会这样。我在 meta.yaml 中遗漏了什么吗？我的 build.sh 是空的，我也不想使用 "script: "{{ PYTHON }} -m pip install 。--no-deps --ignore-installed -vv "" 如果我不需要，因为那时我还需要一个 setup.py。
