在没有互联网访问的情况下安装 pythonnet

Question

我正在尝试在无法访问 Internet 的计算机上安装 pythonnet。在连接的机器上，我从 Github 下载了 pythonnet-master.zip，从 pypi.

下载了 pythonnet-2.4.0.tar.gz

当我尝试 pip install pythonnet-2.4.0.tar.gz 时，出现错误 The remote name could not be resolved: 'www.nuget.org.

然后我用 conda install nuget-3.2.0.10516-py34_0.tar.bz2 来处理 nuget。安装成功，但是还是安装不了pythonnet

我尝试使用 pythonnet-master.zip 和 conda install 也失败了。任何想法都会有所帮助。

这是完整的错误输出：

Answer 1

pythonnet 的 setup.py 正在尝试运行 nugget.exe update --self 由于缺少互联网连接，您的系统失败了。我可以想到两种可能的解决方案：

尝试下载正确的 whl 文件，而不是源安装。在pypi上，只有cp37及以下的。如果你是运行ning pyhton 3.8，可以找到合适的wheel文件here
提取 tar.gz 存档和注释行 424：subprocess.check_call(cmd, shell=use_shell)。然后运行python setup.py install。这将防止安装程序在安装过程中尝试更新 nugget
