在Mac OS X上使用Conda安装pyzbar时出错 [英] Error installing pyzbar with Conda on Mac OS X

问题描述

我正在尝试将项目从Python 3 venv转换为Conda.但是，它不适用于Conda，显然是因为没有支持macOS的存储库.

I am attempting to convert a project from a Python 3 venv to Conda. However, it doesn't work with Conda, apparently because there is no repository that supports macOS.

这令人失望，因为在原始项目中使用 brew 和 pip 安装 zbar 和 pyzbar 可以正常工作.显然，这些文件存在，但无法通过Conda存储库获得.我在某处缺少回购吗?如果没有，是否有办法将通过 pip 和 brew 下载的软件包撬入Conda环境?

This is disappointing because using brew and pip to install zbar and pyzbar in the original project works fine. So clearly the files exist but are not available through Conda repos. Am I missing a repo somewhere? If not, is there a way to crowbar the packages downloaded with pip and brew into a Conda environment?

这就是我尝试过的.

我参见说明，其中说要使用 conda install -c lightsource2-tagpyzbar .但是，Conda无法解决(此注释底部的完整错误消息).

I see instructions which say to use conda install -c lightsource2-tag pyzbar. However Conda fails to resolve (complete error message at the bottom of this note).

这似乎与搜索 https://anaconda.org/search?q=pyzbar的结果一致.列出的唯一存储库适用于Linux和Win32.

This seems consistent with the results of searching https://anaconda.org/search?q=pyzbar . The only repos listed are for Linux and win32.

推荐答案

是的，看来 pyzbar 无法通过 osx-64 平台的Anaconda Cloud渠道使用.取而代之的是，可以(谨慎地)混合使用PyPI和Conda软件包.例如，基本的YAML定义应类似于:

Yes, it looks like pyzbar is not available through Anaconda Cloud channels for osx-64 platform. Instead, one can (cautiously) mix PyPI and Conda packages. For example, a basic YAML definition would be something like:

zbar_env.yaml

name: zbar_env
channels:
 - conda-forge
 - defaults
dependencies:
 - python=3
 - zbar
 - pip
 - pip:
   - pyzbar

可以用以下方法实例化:

which can be instantiated with:

conda env create -f zbar_env.yaml

按照

As per the recommendations for mixing PyPI and Conda, place all requirements in this YAML file from the start. If you need to add something new, edit the YAML and recreate the env.

或者，您可以切换到 zbarlight ，可通过Conda Forge获得，并且似乎保持不变.

Alternatively, you could switch to zbarlight, which is available through Conda Forge and appears to be consistently maintained.
