使用 python3.5 pip 安装 Numpy

Question

我遇到了很多关于安装 numpy 包的问题。当我执行 pip commande

pip install numpy

我收到以下错误

Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ConnectTimeoutError(, 'Connection to pypi.python.org timed out. (connect timeout=15)')': /simple/numpy/Could not find a version that satisfies the requirement numpy (from versions: ) No matching distribution found for numpy

当我使用 easy_insall 命令时，出现以下错误

Searching for numpy timed out -- Some packages may not be found! Couldn't find index page for 'numpy' (maybe misspelled?) Scanning index of all packages (this may take a while) Reading https://pypi.python.org/simple/ Download error on https://pypi.python.org/simple/: timed out -- Some packages may not be found! No local packages or download links found for numpy error: Could not find suitable distribution for Requirement.parse('numpy')

当我使用手动包添加时

python setup.py install

我收到以下错误：

需要帮助。

Answer 1

您可以随时下载 Numpy 安装程序

Answer 2

pip 的错误表明您有 pip 连接问题。我认为您在尝试运行 pip 安装时没有正确设置代理。请检查 this question。您可以尝试 pip 的 --proxy 选项。否则，我不建议手动安装 numpy。

Answer 3

可能是网络问题，您可以再试一次。（对我有用）
