在具有Python 2.7默认版本的Ubuntu 16.04上,我正在尝试安装Apache airflow,但是遇到了几个问题,目前我能看到
apache initdb
Traceback (most recent call last):
File "/usr/local/bin/airflow", line 21, in <module>

from werkzeug.wrappers.json import JSONMixin as _JSONMixin
ImportError: No module named json
到目前为止,已经尝试过这些事情:
$ sudo apt-get install build-essential autoconf libtool pkg-config python-opengl python-imaging python-pyrex python-pyside.qtopengl idle-python2.7 qt4-dev-tools qt4-designer libqtgui4 libqtcore4 libqt4-xml libqt4-test libqt4-script libqt4-network libqt4-dbus python-qt4 python-qt4-gl libgle3 python-dev
sudo pip install -U Werkzeug==0.14.1
sudo pip install -U Jinja2==2.10.1
也尝试过
pip install jsonate
pip install json # (this did not work)
python
Python 2.7.12 (default, Nov 12 2018, 14:36:49)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import json
>>> exit()
到目前为止什么都没做。

已知问题,并在ASF Mail Archives
中对此问题进行了描述。我们从apache master移除了不兼容的Werkzeug库 周末。它导致气流安装失败。
要解决此问题,请以正确的版本手动安装werkzeug库:
pip install werkzeug>=0.15.0
如邮件列表中所述,这似乎是暂时的问题,此解决方案是一种解决方法。在1.10.3版中遇到此问题。

在Mac上安装apache-airflow时,出现以下错误:
错误:apache-airflow 1.10.3要求jinja2 <= 2.10.0,> = 2.7.3,但您将拥有不兼容的jinja2 2.10.1。 错误:apache-airflow 1.10.3要求werkzeug <0.15.0,> = 0.14.1,但是您将拥有不兼容的werkzeug 0.15.4。
重新安装werkzeug和jinja对我有用。
pip install jinja2>=2.10.0
pip install werkzeug>=0.15.0
