pip安装openpyxl失败--如何克服proxy

Question

我正在尝试安装 python 库 openpyxl。我刚刚在我的 windows 10 工作电脑上安装了 python 3.6。我的安装尝试的结果如下。

我发现了一个相关问题：pip install and custom index url

如果我的问题是使用代理，我能做些什么来安装 openpyxl 吗？

C:\Users[=10=]168070>pip install openpyxl

Collecting openpyxl Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError>(': Failed to establish a new connection: [Errno 11002] getaddrinfo failed',)': /simple/openpyxl/

Could not find a version that satisfies the requirement openpyxl (from versions: )

您的本地网络状态似乎无法解析主机名。也许你可以尝试从源代码安装，下面是我的步骤：

1:下载源码：

https://pypi.python.org/pypi/openpyxl

2：构建并安装：

python3.6 setup.py install

3：输出：

4:导入和使用:

Answer 2

在我的案例中，从 wheel 安装有效：我必须在没有互联网的公司 LAN 服务器 (Win) 上安装 openpyxl 该解决方案基于 https://github.com/winpython/winpython/issues/600 即

pip install openpyxl-3.0.9-py2.py3-none-any.whl --no-index --trusted-host=None --find-links=C:\__the_whl_dir__

起初，这没有用，抱怨

ERROR: Could not find a version that satisfies the requirement et-xmlfile (from openpyxl) (from versions: none) ERROR: No matching distribution found for et-xmlfile

正在下载，复制et_xmlfile-1.1.0-py3-none-any.whl到同一个目录，运行再次pip安装，成功
