篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在Ubuntu 18.04上安装pythonnet，在Python 3.6.7 64位，Mono 5.16上安装失败相关的知识，希望对你有一定的参考价值。

我想在Ubuntu上安装pythonnet，但它失败了。

那是我到目前为止所尝试的：

/usr/bin/python3 -m pip install -U pythonnet --user

错误：

  Failed building wheel for pythonnet

我在https://github.com/pythonnet/pythonnet/wiki/Installation看了一眼，但没有帮助。

所以这也失败了：

/usr/bin/python3 -m pip install git+https://github.com/pythonnet/pythonnet --user

无论有没有--egg选项，我都尝试过。

顺便说一句，我在代理服务器后面。所以我也尝试为NuGet设置代理服务器，请参阅NuGet Behind Proxy：

mono /usr/lib/nuget/nuget.exe config -set http_proxy=http://my.proxy.address:port

知道我做错了什么吗？

答案

我能够使用以下命令安装它：

sudo apt-get install clang
sudo apt-get install libglib2.0-dev
sudo apt update
sudo apt install git
sudo apt install nuget
git config --global http.proxy http://my.proxy.address:port
mono /usr/lib/nuget/nuget.exe config -set http_proxy=http://my.proxy.address:port
/usr/bin/python3 -m pip install -U pycparser --user
/usr/bin/python3 -m pip install -U git+https://github.com/pythonnet/pythonnet --user --egg
另一答案

更改相关文件的所有权。我与dotnet类似，我所做的是更改文件或文件夹的所有权。

sudo chown -R $user:$user /path_to_file
