运行require.txt时出错

Question

我正在尝试为我的Django项目创建requirements.txt。我通过https://pip.readthedocs.org/en/1.1/requirements.html并相应地去尝试我requirement.txt

Django==1.8.4 
django-autocomplete-light 
django-cors-headers 
django-watson 
django-filter 
django-import-export 
MySQL-python 
Pillow 
jsonpickle 
mysql-connector-python --allow-external mysql-connector-python 
python-amazon-product-api 
lxml 
similarityPy 
coverage 
django-redis-cache 
redis 
django-debreach 

错误，我得到的是：

------------------------------------------------------------ 
/usr/bin/pip run on Mon Dec 7 20:36:32 2015 
Exception:

    raise ValueError("Expected "+item_name+" in",line,"at",line[p:]) 
ValueError: ('Expected version spec in', 'mysql-connector-python --allow-external mysql-connector-python', 'at', ' --allow-external mysql-connector-python') 

缺少什么我在这里？

此行是无效的requirements.txt文件：

mysql-connector-python --allow-external mysql-connector-python 

我觉得这样做的格式是：

--allow-external mysql-connector-python 
mysql-connector-python 

即像--allow-external mysql-connector-python，这将是一个命令行应该出现在它自己的行上

https://pip.readthedocs.org/en/stable/reference/pip_install/#requirements-file-format

这也是一个点要求文件无效（！）：

apt-get install redis-server
