我正在尝试安装本地版本的 ScrumDo 进行测试。只有这样我才能在我的安装中找到我必须运行的点：

源 bin/激活
pip install -r requirements.txt

我得到错误：

下载/解压 django-storages

无法获取索引基础 URL http : //b.pypi.python.org/simple/
找不到任何满足 django-storages 要求的下载

没有找到 django-
storages 的发行版在 ./pip-log.txt 中存储完整的日志

我用谷歌搜索了一下，在这里和 Stack Overflow 上搜索，发现我应该添加一个 --proxy= 选项和/或取消设置我的 http_proxy 环境变量。然而我的安装没有代理并且没有设置环境变量。我试着跑步

pip install -r requirements.txt --proxy=

然而错误仍然是一样的。我还创建了一个 /root/.pip/pip.conf 包含：

[全局]
index-url = http : //b.pypi.python.org/simple

并检查服务器实际上是在线的，如果包 django-storages 存在，这都是真的。

我尝试的最后一件事，因为ScrumDo 的安装文档是这样说的：

pip install -U Django==1.1.4

再次没有成功......错误总是保持不变，有人有任何想法吗？

我的 pip-error.log 显示以下内容（该 URL 在同一网络中的另一台机器上的 Firefox 中工作，该机器也没有使用代理，我可以从同一台机器上 ping 它）：

如果您最近尝试使用 pip 安装软件包，您可能会遇到此错误：

这似乎是旧版本的 OpenSSL 与 pip 1.3.1 不兼容的问题。如果您使用的是非库存 Python 发行版（尤其是 EPD 7.3），那么您很可能有一个在没有大量工作的情况下无法与 pip 1.3.1 一起使用的设置。

目前最简单的解决方法是安装不需要 SSL 的 pip 1.2.1：

curl -o https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
tar xvfz pip-1.2.1.tar.gz
cd pip-1.2.1
python setup.py install

如果您正在使用 EPD，并且您没有将它用于可能会出现问题的课程，您可能需要考虑安装新的化身：Enthought Canopy。我知道他们知道以前版本的 OpenSSL 引起的问题，并且会想象他们现在使用的新版本应该可以很好地与 pip 1.3.1 配合使用。

您可以尝试自行安装 django-storages .. 试试这个？

sudo pip install https://bitbucket.org/david/django-storages/get/def732408163.zip

尝试在命令中提供代理设置

pip --proxy=http://user:password@Proxy:PortNumber install -r requirements.txt

或尝试

export http_proxy=http://user:password@Proxy:PortNumber

这个问题很可能是DNS设置造成的：服务器无法解析域名，所以无法下载包。

解决方案：sudo nano /etc/network/interface

添加一行：dns-nameservers 8.8.8.8

保存文件并退出

    sudo ifdown eth0 && sudo ifup eth0

然后 pip install 现在应该可以工作了。
