安装pythonnet，没有互联网接入

Question

我试图在一台没有互联网接入的机器上安装pythonnet。在一台连接的机器上，我从Github下载pythonnet-master.zip . pypi，从pypi下载pythonnet-2.4.0.tar.gz。

当我尝试pip install pythonnet-2.4.0.tar.gz时，我得到了错误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来照顾nuget。安装是成功的，但我仍然不能安装pythonnet。

我使用pythonnet. and和conda install的尝试也失败了。任何想法都会有帮助。

以下是完整的错误输出：

Answer 1

setup.py of pythonnet正在尝试运行nugget.exe update --self，由于缺少internet连接，该系统在您的系统中失败。我可以想到两种可能的解决方案：

1. 尝试下载正确的whl文件，而不是安装源代码。在pypi上，只有cp37和更低的版本。如果您正在运行pyhton3.8，您可以找到正确的车轮文件这里
2. 解压tar.gz存档并注释第424行：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母块。
