python - 在 Conda 环境中安装 Apache-Airflow

Question

现状

我正在尝试安装 apache-airflow使用 pip 进入 conda 环境。我做不到，因为 setup.py egg_info 一直失败:

Command "python setup.py egg_info" failed with error code 1 in C:\Users\joshu\AppData\Local\Temp\pip-install-3efyslfh\apache-airflow\

运行时的消息

pip install "apache-airflow[s3, postgres]"

我在 Windows cmd 中运行它，然后在 cmd 中以管理员身份再次执行所有步骤(打开 cmd 时按 shift+enter)。

(myVenv) C:\Users\joshu\Documents>pip install "apache-airflow[s3, postgres]"
Collecting apache-airflow[postgres,s3]

Command "python setup.py egg_info" failed with error code 1 in C:\Users\joshu\AppData\Local\Temp\pip-install-3efyslfh\apache-airflow\

我采取的步骤

1)我首先创建了一个conda环境，并在环境中安装了pip和setuptools:

C:\Users\joshu\Documents>conda create -n airflow pip setuptools
Solving environment: done


==> WARNING: A newer version of conda exists. <==
  current version: 4.5.4
  latest version: 4.5.10

Please update conda by running

    $ conda update -n base conda



## Package Plan ##

完成此设置后，运行 pip install apache-airflow 会在本页顶部显示错误

我采取的其他步骤

1. 在我的系统上安装 apache-airflow(无 conda 环境)。这行得通，但我希望将其包含在环境中。
2. 升级设置工具:

代码:

最终，我希望在 conda 环境中获得项目所需的 Airflow 和相关包。

Answer 1

错误似乎是因为 async is a reserved keyword in Python 3.7并且这个包还没有更新他们的 setup.py 脚本。在软件包更新之前，您可以使用 Python 3.6

conda create -n airflow pip setuptools python=3.6
conda activate airflow
pip install "apache-airflow[s3, postgres]"
