IronPython:没有名为json的模块 [英] IronPython: No module named json

问题描述

我已经安装了IronPython

I have IronPython installed

我的python文件看起来像这样:

My python file looks like this:

import sys
print(sys.version)
import json

运行它的代码:

var p = Python.CreateEngine();
var scope = p.CreateScope();
p.ExecuteFile("Test.py", scope);

它打印出:

2.7.7(.NET 4.0.30319.42000(32位)上的IronPython 2.7.7(2.7.7.0))

2.7.7 (IronPython 2.7.7 (2.7.7.0) on .NET 4.0.30319.42000 (32-bit))

但随后失败，但出现以下异常:

But then fails with the exception:

没有名为json的模块

No module named json

据我了解，此版本的IronPython中应包含json模块.

As I understand the json module should be included in this version of IronPython.

为什么会出现此错误?

推荐答案

我很快发现Visual Studio中的交互式python窗口没有引发此错误.

I soon discovered that the interactive python window in Visual Studio did not throw this error.

print sys.path还为交互式窗口和相关文件显示了不同的值.它仅包含bin/Debug文件夹中的路径.

print sys.path also showed different values for the interactive window and the file in question. It only included paths from the bin/Debug folder.

一个人可以轻松添加正确的路径:

One can easily add the correct paths:

var p = Python.CreateEngine();
var scope = p.CreateScope();
var libs = new[] {
    "C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\Extensions\\Microsoft\\Python Tools for Visual Studio\\2.2",
    "C:\\Program Files (x86)\\IronPython 2.7\\Lib",
    "C:\\Program Files (x86)\\IronPython 2.7\\DLLs",
    "C:\\Program Files (x86)\\IronPython 2.7",
    "C:\\Program Files (x86)\\IronPython 2.7\\lib\\site-packages"
};

p.SetSearchPaths(libs);
p.ExecuteFile("Test.py", scope);
