在Conda环境中安装Apache-Airflow

情况

我正在尝试使用pip将apache- airflow安装到conda环境中。我无法执行此操作，因为setup.py egg_info一直失败：

命令“ python setup.py egg_info”在C：\ Users \ joshu \ AppData \ Local \ Temp \ pip-install-3efyslfh \ apache-airflow \中失败，错误代码为1

我跑步时的讯息

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

我在Windows cmd中运行了此命令，然后以cmd中的管理员身份再次执行了所有步骤（在打开cmd时按Shift + Enter）。

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

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，并将pip和setuptools安装到该环境中：

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 ##

  environment location: C:\Users\joshu\Anaconda3\envs\airflow

  added / updated specs:
    - pip
    - setuptools


The following NEW packages will be INSTALLED:

    certifi:        2018.8.13-py37_0
    pip:            10.0.1-py37_0

完成此设置后，运行pip install apache-airflow会在此页面顶部显示错误

我采取的其他步骤

1. 在我的系统上安装apache-airflow（无conda环境）。这可行，但我希望将其包含在环境中。
2. 升级setuptools：

(airflow) C:\Users\joshu\Documents>pip install --upgrade setuptools

最终，我希望在conda环境中获得项目所需的气流和相关程序包。
