安装带有Pip1.5的外部未验证包

Question

我试图在Ubuntu14.04上使用pip1.5.5和Python2.7.6安装django-admin-tools 0.5.1。

我第一次尝试：

$ pip install django-admin-tools==0.5.1
Downloading/unpacking django-admin-tools==0.5.1
  Could not find a version that satisfies the requirement django-admin-tools==0.5.1 (from versions: 0.4.0)
  Some externally hosted files were ignored (use --allow-external to allow).
Cleaning up...
No distributions matching the version for django-admin-tools==0.5.1
Storing debug log for failure in /tmp/tmpd5Tb2I

'pip help install'的文档显示：

 --allow-external <package>  Allow the installation of externally hosted files

在启用该标志时尝试：

$ pip install --allow-external django-admin-tools==0.5.1                                                                                                                 
You must give at least one requirement to install (see "pip help install")

太奇怪了。经过一些修改后，我发现外部包URL不是https (setup.py)。所以我试着用旗子--allow-unverified

$ pip install --allow-external --allow-unverified django-admin-tools==0.5.1                                                                                              
Downloading/unpacking django-admin-tools==0.5.1
  Could not find a version that satisfies the requirement django-admin-tools==0.5.1 (from versions: 0.4.0)
  Some externally hosted files were ignored (use --allow-external to allow).
Cleaning up...
No distributions matching the version for django-admin-tools==0.5.1

我用错了吗？如何解决这个问题，并使用pip安装django管理工具？

Answer 1

试着调用：

pip install django-admin-tools==0.5.1 --allow-external django-admin-tools --allow-unverified django-admin-tools

Answer 2

--allow-unverified和--allow-external都使用包名作为参数。

From pip help install:
--allow-external <package>   Allow the installation of a package even if it
                             is externally hosted
--allow-unverified <package> Allow the installation of a package even if it 
                             is hosted in an insecure and unverifiable way

所以你的用法应该是

pip install <pkg> --allow-unverified <pkg> --allow-external <pkg>

或者说有点困惑：

pip install --allow-unverified <pkg> --allow-external <pkg> <pkg>

Answer 3

我找到了解决办法：

$ pip install django-admin-tools==0.5.1 --allow-unverified django-admin-tools
