在 python 中安装包时出错

Question

我可以尝试使用 pip 在 python 3.6.4 中安装软件包，但我发现了很多错误。我也尝试像这样的命令：easy_install, pip install --upgrade --force-reinstall <package>, pip install --ignore-installed <package>。错误结果总是一样的：

 Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x000002E91DCF04E0>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed',)': /simple/<package>/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x000002E91DCF0BE0>: Failed to establish a new connection: [Errno 11002] getaddrinfo failed',)': /simple/<package>/

我认为我没有到达https://pypi.python.org/simple

Answer 1

我认为我没有到达https://pypi.python.org/simple/

如果没有其他方法，仍然尝试在浏览器中手动打开https://pypi.python.org/simple/。每个主要 Python 包的每个版本都有下载链接。在我的情况下，安装在我的 Visual Studio 中的 Windows 10 中不起作用，所以我手动下载了每个包，然后再次手动安装它们，类似于

C:\Users\myself>"C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\scripts\pip" 安装 C:\Users\myself\Downloads\jupyter-1.0.0.tar。 gz

如果安装显示找不到另一个模块，则下载并安装缺少的模块，然后对原始模块重复该命令，看看可能缺少其他模块等等。需要一段时间，但可以得到结果。

Answer 2

在 https://pypi.org/ 上手动搜索软件包，下载相应的 .whl 文件并通过 (Anaconda) 命令行安装它们是我在 Windows 10 机器上唯一可行的方法。
