pythonnet的构建轮子失败

Question

我正在尝试连接控制器以进行 python 实验。目前，这是我正在尝试运行的代码

import sys

print('adding location of IOPortClientLib.dll & Newport.CONEXAGP.CommandInterfacedll to sys.path')
sys.path.append(r'C:\Program Files\Newport\Piezo Motion Control\Newport CONEX-AGP Applet\Bin')

import clr
clr.AddReference('Newport.CONEXAGP.CommandInterface.dll')

我得到两个不同的结果：

1. 我从 Ubuntu (WSL) 得到

adding location of IOPortClientLib.dll & Newport.CONEXAGP.CommandInterfacedll to sys.path
Traceback (most recent call last):
  File "conex_test.py", line 7, in <module>
    clr.AddReference('Newport.CONEXAGP.CommandInterface.dll')
AttributeError: module 'clr' has no attribute 'AddReference'

1. 从 python3 IDLE，我得到了

adding location of IOPortClientLib.dll & Newport.CONEXAGP.CommandInterfacedll to sys.path
Traceback (most recent call last):
  File "C:\Users\natal\Box Sync\Downer group (ndf367@eid.utexas.edu)\Sandia\code\python\conex_test.py", line 6, in <module>
    import clr
ModuleNotFoundError: No module named 'clr'

当我搜索这些错误时，建议我安装pythonnet，所以我在Ubuntu中运行pip3 install pythonnet，这是输出

To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

我尝试更新setuptools 和wheel，就像建议的here 一样，但我得到了同样的错误。我错过了什么？

Answer 1

可能的重复：

• Pip Pythonnet option --single-version-externally-managed not recognized
• Pip error: option --single-version-externally-managed not recognized

我回答了@Pip Pythonnet option --single-version-externally-managed not recognized 的问题。我的答案是使用支持 Python.NET 的旧版 Python。

应列出当前 Python.NET 支持的版本@http://pythonnet.github.io/。
