我正在尝试使用安装Python库pip,收到SSL错误:

~/projects/base ? pre-master±  pip install xdict

Collecting xdict
  Could not fetch URL https://pypi.python.org/simple/xdict/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
  Could not find a version that satisfies the requirement xdict (from versions: )
No matching distribution found for xdict

点数版本:pip 9.0.1

我该如何解决这个错误？

python中的许多操作都需要通过https访问.这包括pip安装,或仅使用http.client.HTTPSConnection,或内部使用这些内容的任何模块或应用程序.

如果python是从官方的python pkg安装程序安装的,从https://python.org下载,那么它使用的是openssl的内部版本,并且不包含根证书.任何使用SSL连接的内容都会导致此错误:

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)

如何安装根证书以使上述错误消失？

我正在加入一个项目,所以我想建立环境,所以我做的是:

pip install -r requirements.txt

这完全安装了所有要求,包括django 1.7.0,Pillow 2.4.0和其他一些.

然后我想构建数据库:

python manage.py migrate

繁荣,错误,我得到以下:

CommandError: System check identified some issues:

出乎意料的是，Python 代码上的 API“请求”开始出现此错误：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/requests/api.py", line 55, in get

在搜索了很多东西后，我找到了一些可供下载的软件包。但这也引发了错误：

所以，我注意到的主要事情是

无法获取 URL https://pypi.python.org/simple/pip/：403客户端错误：需要 SNI

请告知这是什么以及如何解决这个问题。提前致谢！

我经常得到

Cannot fetch index base URL https://pypi.python.org/simple/

每当我尝试使用最新的pip版本来安装任何东西时.

我读了一些其他问题,pip在其最新版本中遇到了SSL相关问题,并建议安装pip 1.2.1.

如何通过easy_install安装特定版本的pip？
