Question

在我的代码中，我使用的是configparser：

from configparser import ConfigParser

我正在使用pip冻结来生成我的requirements.txt

pip freeze > requirements.txt

对于configparser，它正在编写

configparser==3.3.0.post2

但是当我通过docker build从docker容器中执行pip install -r requirements.txt时失败了：

docker build -t denzel .

Downloading/unpacking configparser==3.3.0.post2 (from -r /home/denzel/requirements.txt (line 2))
Could not find a version that satisfies the requirement configparser==3.3.0.post2 (from -r /home/denzel/requirements.txt (line 2)) (from versions: 3.2.0r1, 3.2.0r2, 3.2.0r3, 3.3.0r1, 3.3.0r2, 3.5.0b1, 3.5.0b2)
Cleaning up...
No distributions matching the version for configparser==3.3.0.post2 (from -r /home/denzel/requirements.txt (line 2))

但是这可以通过pip install本地工作：

 pip install -r requirements.txt
Requirement already satisfied (use --upgrade to upgrade): aniso8601==1.1.0 in ./env/lib/python2.7/site-packages (from -r requirements.txt (line 1))
Requirement already satisfied (use --upgrade to upgrade): configparser==3.3.0.post2 in ./env/lib/python2.7/site-packages (from -r requirements.txt (line 2))
....
....

注意：我通过删除版本并使用configparser来修复此问题，没有版本。仍然想发布我的问题，以了解它失败的原因。

以下内容适用于docker

app.py

from configparser import ConfigParser
config = ConfigParser()
config.read('app.conf')
_var = config.get(‘Section’, 'Status')

print (_var)

requirements.txt

configparser

以下操作将在本地进行

app.py

import ConfigParser
config = ConfigParser.ConfigParser()
config.read('app.conf')
_var = config.get(‘Section’, 'Status')

print (_var)

requirements.txt
