情况
我正在尝试使用pip将apache-airflow安装到conda环境中。我无法，因为setup.py egg_info一直失败：
命令“python setup.py egg_info”失败，错误代码1在C： Users joshu AppData Local Temp pip-install-3efyslfh apache-airflow
我跑的时候留言
pip install "apache-airflow[s3, postgres]"
我在Windows cmd中运行它，然后在cmd中再次执行所有步骤（在打开cmd时shift + enter）。
(myVenv) C:UsersjoshuDocuments>pip install "apache-airflow[s3, postgres]"
Collecting apache-airflow[postgres,s3]

Complete output from command python setup.py egg_info:

我采取的步骤
1）我首先创建了一个conda环境，并将pip和setuptools安装到环境中：
C:UsersjoshuDocuments>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:UsersjoshuAnaconda3envsairflow
added / updated specs:
- pip
- setuptools
The following NEW packages will be INSTALLED:
certifi: 2018.8.13-py37_0

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
- 在我的系统上安装apache-airflow（没有conda环境）。这有效，但我希望它包含在一个环境中。
- 升级setuptools：
(airflow) C:UsersjoshuDocuments>pip install --upgrade setuptools

(airflow) C:UsersjoshuDocuments>pip install "apache-airflow[s3, postgres]"
最后，我想在conda环境中为我的项目提供所需的气流和相关包。
答案
错误似乎是因为async is a reserved keyword in Python 3.7和这个包没有更新他们的setup.py脚本。您可以使用Python 3.6直到更新包
conda create -n airflow pip setuptools python=3.6
pip install "apache-airflow[s3, postgres]"
另一答案
我也有同样的问题。我通过使用conda而不是pip来解决它：
conda install -c conda-forge airflow
https://anaconda.org/conda-forge/airflow
另一答案
我遇到了同样的问题。 Apache Airflow 1.10不兼容。
我的解决方案是构建源代码。我通过git获得了最新的源代码。此命令在dist目录中创建一个wheel文件。
python3 setup.py bdist_wheel
然后你安装
pip3 install apache_airflow-2.0.0.dev0+incubating-py3-none-any.whl
