在aliyun linux 上，安装caravel，创建admin用户时报 unable to import caravel Error: invalid syntax (views.py, line 613)

Question

根据官网文档，在aliyun linux 上安装caravel，在执行fabmanager create-admin --app caravel命令，录入邮箱后，出现问题:

Added Permission menu access on Permission on Views/Menus to role Admin Was unable to import caravel Error: invalid syntax (views.py, line 613)

----请教大神怎么解决？不会python，难道要改views.py的代码吗？

--------------------安装过程如下---------------------

os：aliyun linux 

1.执行yum upgrade python-setuptools失败，直接官网下载setuptools-20.7.0，安装

2.执行yum install gcc libffi-devel python-devel python-pip python-wheel openssl-devel报错
强制安装nose ，$ pip install -U --force --user nose

3.继续按官网说明操作，一直到这步：fabmanager create-admin --app caravel

--------------------详细日志如下---------------------

Was unable to import caravel Error: invalid syntax (views.py, line 613)
------------------------------------------------

Answer 1

使用python3.6,安装它，但是在执行fabmanager create-admin --app superset时候报错：

Was unable to import superset Error: module 'xml.etree.ElementTree' has no attribute '_IterParseIterator'

Answer 2

官方安装说明页第一行就写得很明确，只支持2.7，2.6不行。升级版本吧。

Caravel is currently only tested using Python 2.7.*. Python 3 support is on the roadmap, Python 2.6 won’t be supported.

Answer 3

执行fabmanager create-admin --app caravel 报错： raise DistributionNotFound(req) pkg_resources.DistributionNotFound: Flask-WTF>=0.9.1

Answer 4

可以跑起来，我已经部署了一个

Answer 5

主要检查cryptography、pandas是否安装成功，没成功要手动安装，cryptography不支持python2.6

Answer 6

可能是python的版本太低了，aliyun linux自带的是2.6.6的python，正在升级

Answer 7

在搞其它事，没把安装过程发上来，现在补下

-----------先看一下官方文档操作-------------
1> aliyun linux对应的是这块系统依赖安装命令:
yum upgrade python-setuptools
yum install gcc libffi-devel python-devel python-pip python-wheel openssl-devel
2> 安装caravel及其样例
# Install caravel
pip install caravel
# Create an admin user
fabmanager create-admin --app caravel
# Initialize the database
caravel db upgrade
# Create default roles and permissions
caravel init
# Load some data to play with
caravel load_examples
# Start the development web server
caravel runserver -d
-------------安装成功的过程记录-------------
1.安装python2.7（系统自带python版本太低2.6.6，caravel需要2.7版）
2.安装pip
pip下载页面https://pypi.python.org/pypi/pip
$ wget https://pypi.python.org/packages/source/p/pip/pip-7.1.0.tar.gz
$ cd pip-7.1.0
$ python setup.py install
3.安装setuptools
$ wget https://pypi.python.org/packages/source/s/setuptools/setuptools-20.7.0.tar.gz
$ tar -zxvf setuptools-20.7.0.tar.gz
$ cd setuptools-20.7.0
$ python setup.py install
4、根据官方文档操作，在执行到fabmanager create-admin --app caravel时，提示：fabmanager not found 
将fab添加至PATH变量中，
$ export PATH=$PATH:/usr/local/python2.7/bin
若没安装fab，下载解压安装后，再添加
$ wget https://pypi.python.org/packages/source/f/fab/fab-1.4.2.tar.gz#md5=45b945bdde70995868ef1497664a11d7
$ tar -zxvf fab-1.4.2.tar.gz
$ cd fab-1.4.2
$ python setup.py install
5、继续官方文档操作，一路畅通
