pip install <package name>对我而言,每个包都失败了.这就是我得到的:

Could not find a version that satisfies the requirement <package-name
(from versions: )
No matching distribution found for <package-name>

我在Stack Overflow上看到了 类似的 问题,但它们似乎与这个问题没有完全相关.

此外,这篇文章表明,如果PyPI关闭或我的IP地址被列入黑名单,可能会发生这种情况.对我来说,这似乎都不正确.

pip显示最新的运行情况pip install --upgrade pip.

我最近需要安装一些软件包

pip install future
pip install scikit-learn
pip install numpy
pip install scipy

我也尝试过sudo在他们面前写过但是所有这些都是红线中出现以下错误:

sudo pip3 install scikit-learn (任何模块真的只是使用最近的尝试)

sudo pip3 install -U scikit-learn

sudo -H pip3 install -U scikit-learn

sudo -H pip3 --default-timeout=200 install -U scikit-learn

sudo python3 -m pip install scikit-learn

每个命令和上述任何组合都会导致相同的错误:读取超时.错误总是发生在同一点(scikit-learn发生在24%).我正在使用最新版本的pip(8.1.2),而我正在使用ubuntu mate 16.04.确切的错误是:
