Question

我正在尝试为我的Django项目创建 requirement.txt 。我经历了https://pip.readthedocs.org/en/1.1/requirements.html并相应地尝试了我的 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

我得到的错误是：

------------------------------------------------------------
/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')

我在这里缺少什么？

Answer 1

此行在requirements.txt文件中无效：

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

我认为这样做的格式是：

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

即。像--allow-external mysql-connector-python之类的东西，它将是一个命令行arg to pip本身，应该出现在它自己的行上

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

这在pip要求文件中也是无效的（！）：

apt-get install redis-server

运行requirement.txt时出错
