使用Python"pip"安装时出错:无法获取索引基URL http://

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步:

source bin/activate
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/
无法找到满足要求的任何下载django-storages

django-
storages 找不到任何发行版存储完整的登录./pip-log.txt

我google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.但我的安装没有代理,并且未设置环境var.我试过跑步

pip install -r requirements.txt --proxy =

但错误仍然是一样的.我还创建了一个/root/.pip/pip.conf,其中包含:

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

并检查它服务器实际上是在线,如果包django-storages存在,这是真的.

我试过的最后一件事,因为ScrumDo的安装文档是这样说的:

pip install -U Django == 1.1.4

再一次没有成功......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(URL在同一网络中不使用代理的另一台机器上的firefox中运行,我可以从同一台机器ping它):

如果您最近尝试使用pip安装软件包,则可能是您遇到此错误:

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.

现在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.我知道他们知道由以前版本的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.

您可以尝试单独安装 django-storages.. 试试这个？

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