我正在寻找一些关于分发Python的最佳方法的建议。Net和我的申请。看来我有两个选择:
1。我的应用程序安装程序运行pip install pythonnet
缺点是客户需要在安装时连接互联网。
2。捆绑Python。Net文件与我的应用程序允许离线安装
我喜欢一个可以离线运行的"独立"安装程序的想法，但是这是一个好主意吗?它需要安装正确版本的Python。. Net与客户安装的Python版本匹配。
我尝试了以下步骤:
C:mkdir download pythonnet
cd download pythonnet
pip download pythonnet <-- this gets two files: pythonnet-2.5.2.tar.gz and pycparser-2.20-py2.py3-none-any.whl
<disconnect from the internet>
pip install C:pythonnet_downloadpythonnet-2.5.2.tar.gz
Processing c:pythonnet_downloadpythonnet-2.5.2.tar.gz
Requirement already satisfied: pycparser in c:program filespython39libsite-packages (from pythonnet==2.5.2) (2.20)

- 为什么以上步骤失败?
- 如果我让这个工作，它将允许创建一个Python。网轮哪个匹配安装的Python版本?
注意:我能够通过以下步骤获得离线安装工作，但这是使用特定于我安装的Python版本的轮子。我希望它能与客户拥有的任何Python版本一起工作。
pip install pythonnet
< search in C:UsersvinceAppDataLocalpipcachewheels for pythonnet-2.5.2-cp39-cp39-win_amd64.whl and copy it to C:copy_of_pythonnet_wheel >
pip uninstall pythonnet
pip install C:copy_of_pythonnet_wheelpythonnet-2.5.2-cp39-cp39-win_amd64.whl
Python.Runtime.dll相关问题:
如果我使用在线安装程序(pip install pythonnet)，它会将Python.Runtime.dll放在site-packages目录中，例如:C:Program FilesPython39Lib site-packages。我的。net应用程序应该加载这个Python.Runtime.dll，还是应该使用我编译我的。net项目所针对的Python.Runtime.dll，因此已经安装在C:Program Files MyDotNetExeLocation中?
如果是前者，我如何指定Python.Runtime.dll的位置?位置取决于用户决定在哪里安装Python，所以我不知道在哪里找到它。我能想到的一个解决方案是:在我的安装程序安装了Python之后。Net，它检查站点包的位置使用:
py.exe -c "import site; print(next(item for item in site.getsitepackages() if 'site-packages' in item))"
然后从这个目录复制Python.Runtime.dll到C:Program Files MyDotNetExeLocation
即将推出的Python。不需要使用pip安装。NET 3.0来启用Python嵌入到。NET项目中。你可以从GitHubsrc/runtime目录构建它，或者从NuGet.org获取最新的每月预览版本。
你的应用程序需要将Runtime.PythonDLL设置为python39.dll和PythonEngine.PythonHome到Python主目录的完整路径(在Windows上通常是python39.dll所在的目录)。
