Question

我有很多问题需要安装numpy包。当我执行pip commande

时

pip install numpy

我收到以下错误

重试（重试（总计= 4，连接=无，读取=无，重定向=无））连接被＆＃39; ConnectTimeoutError（＆＃39;连接到pypi.python.org超时）后断开。（ connect timeout = 15）＆＃39;）＆＃39;：/ simple / numpy /找不到满足要求numpy的版本（来自版本:) 找不到numpy
的匹配分布

当我使用easy_insall命令时，我收到以下错误

搜索numpy超时 - 可能找不到某些包裹！无法找到“numpy＆＃39;”的索引页面。（可能拼写错误？）扫描所有包装的索引（这可能需要一段时间）阅读https://pypi.python.org/simple/ 在https://pypi.python.org/simple/上下载错误：超时 - 可能找不到某些包裹！找不到numpy的本地软件包或下载链接错误：找不到Requirement.parse的合适发行版（＆＃39; numpy＆＃39;）

当我使用手动包添加

python setup.py install

我收到以下错误：

请帮助。

Answer 1

您可以随时下载Numpy安装程序

Answer 2

pip错误表明你有一个pip连接问题。我认为你在尝试运行pip install时没有正确设置你的代理。请检查this question。你可以试试pip的--proxy选项。否则，我不建议任何手动安装numpy。

Answer 3

也许是因为网络，您可以重试一次。（对我有用）

Numpy安装python3.5点
