Question

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地方：

来源箱/激活
pip install -r requirements.txt

我收到错误：

下载/解压缩django-storages


无法获取索引库URL http：//b.pypi.python.org/simple/
     找不到满足django-storages要求的任何下载


django-storages没有发现任何发行版   存储完整的登录./pip-log.txt

我google了一下，在这里搜索Stack Overflow并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。但我的安装没有代理，并且未设置环境var。我试过跑

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，其中包含：

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

并检查服务器实际上是否在线，如果存在django-storage包，则两者都是如此。

我尝试的最后一件事，因为install doc of ScrumDo这样说：

pip install -U Django == 1.1.4

再次没有成功......错误始终保持不变，任何人都有任何想法？

我的pip-error.log显示以下内容（该URL在同一网络中不使用代理的不同计算机上的firefox中工作，我可以在同一台计算机上ping它）：

如果您最近尝试使用pip安装软件包，则可能遇到此错误：

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（特别是EPD 7.3），那么您很可能会在没有大量工作的情况下使用pip 1.3.1。

目前简单的解决方法是安装pip 1.2.1，它不需要SSL：

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破坏的类，您可能需要考虑安装新的化身：Enthought Canopy。我知道他们已经知道了以前版本的OpenSSL引起的问题，并且可以想象他们现在正在使用一个新版本，它应该与pip 1.3.1很好地配合。

您可以尝试自行安装django-storages。试试这个吗？

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

Answer 3

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

Answer 4

此问题最有可能是由DNS设置引起的：服务器无法解析域名，因此无法下载该程序包。

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应该正常工作。
