Install anaconda library from a local source
提问by Noel Evans
I have been trying to install pymc for some time on a Windows PC behind a very complicated proxy; effectively making this an installation on a computer not connected to the internet. I have tried - unsuccessfully - to set a proxy in the condarc file but I still get error messages
一段时间以来，我一直试图在一个非常复杂的代理后面的 Windows PC 上安装 pymc；有效地使其安装在未连接到互联网的计算机上。我曾尝试 - 不成功 - 在 condarc 文件中设置代理，但我仍然收到错误消息
conda install -c https://conda.binstar.org/pymcpymc Fetching package metadata: SSL verification error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)
conda install -c https://conda.binstar.org/pymcpymc 获取包元数据：SSL 验证错误：[SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:645)

To solve this, you need to download the tar file (even if using Windows) that the installer is trying to fetch and then use offline mode:
要解决此问题，您需要下载安装程序尝试获取的 tar 文件（即使使用 Windows），然后使用离线模式：
Use this command which will error, to determine the file to be downloaded:
使用这个会出错的命令来确定要下载的文件：
>conda install -c https://conda.binstar.org/pymc pymc
Fetching package metadata: SSL verification error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)

Could not connect to https://repo.continuum.io/pkgs/free/win-64/pymc-2.3.5-np110py35_0.tar.bz2
... [error message continues]...
Now download the tar file mentioned in the error message:
现在下载错误消息中提到的 tar 文件：
https://repo.continuum.io/pkgs/free/win-64/pymc-2.3.5-np110py35_0.tar.bz2
https://repo.continuum.io/pkgs/free/win-64/pymc-2.3.5-np110py35_0.tar.bz2
And then run this command with the path to the tar file:
然后使用 tar 文件的路径运行此命令：
>conda install --offline C:\pymc-2.3.5-np110py35_0.tar.bz2

Just of notes: "-c conda-forge" might be handy for some other packages. For example:
注意事项：“-c conda-forge”可能对其他一些软件包很方便。例如：
conda install -c conda-forge python-levenshtein

Adding to the solution above. Anyone met "SSL verification error" can just turn the verification step off temporarily in ~/.condarc
添加到上面的解决方案中。任何遇到“SSL 验证错误”的人都可以在 ~/.condarc 中暂时关闭验证步骤
channels:
- defaults
ssl_verify: true
In this way, you could install from your local hub.
通过这种方式，您可以从本地集线器安装。
