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”失败，错误代码为1 C：\ Users \ joshu \ AppData \ Local \ Temp \ pip-install-3efyslfh \ apache-airflow \
我跑步时的消息
pip install "apache-airflow[s3, postgres]"
我在Windows cmd中运行了此命令，然后再次在cmd中以管理员身份执行了所有步骤（在打开cmd时按Shift + Enter）。

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

最终，我希望在conda环境中获得项目所需的气流和相关软件包。
答案 0 :(得分：5)
错误似乎是由于async is a reserved keyword in Python 3.7且此软件包尚未更新其setup.py脚本。您可以使用Python 3.6直到软件包更新
conda create -n airflow pip setuptools python=3.6
pip install "apache-airflow[s3, postgres]"

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气流
答案 2 :(得分：0)
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。
handle = reader.makefile()
for line in handle:
filename = "FILE.0000.{:%Y.%m.%d.%H.%M}.txt".format(datetime.datetime.now())
with open(os.path.join('/tmp', filename), "a") as output:
output.write(line)
然后安装
python3 setup.py bdist_wheel
