Question

当我尝试在我的python代码中导入clr时，我收到以下错误：

*** Error in `python': free(): invalid pointer: 0xb0f1a120 ***

我发现了对类似问题的引用（https://mail.python.org/pipermail/pythondotnet/2014-October/001598.html），但我无法弄清楚如何使用npython二进制文件，我不希望在启用共享库的情况下重建python。

任何提示或帮助将不胜感激。

Answer 1

经过一些痛苦的试验后，我在代码中成功使用import clr。

首先，我需要以某种方式使用正确的二进制文件，为了实现我使用pythonnet / pythonnet包的git的最新开发源。

您可以尝试：$ sudo pip install --pre pythonnet下载并安装最新的开发源代码。但请记住，有一些必要条件，所以我附上了travis构建细节

system_info
Build language: python
Operating System:   Ubuntu 12.04 LTS
$ python --version
Python 2.7.9
$ pip --version
pip 6.0.7 from /home/travis/virtualenv/python2.7.9/lib/python2.7/site-packages (python 2.7)
$ sudo apt-get install software-properties-common
$ sudo add-apt-repository -y "deb http://archive.ubuntu.com/ubuntu/ trusty main universe"
$ sudo apt-get -qq install mono-devel mono-gmcs mono-xbuild nunit-console
$ sudo mozroots --import --machine --sync
$ yes | sudo certmgr -ssl -m https://go.microsoft.com
$ yes | sudo certmgr -ssl -m https://nugetgallery.blob.core.windows.net
$ yes | sudo certmgr -ssl -m https://nuget.org
$ pip install six

现在通常用pip安装pythonnet应该成功执行，你可以尝试在你的python代码中调用import clr。在我个人的情况下，即使在这种情况下，它也是失败的，尽管安装没有错误。原因是虽然我的python是在没有--enable-shared，运行

的情况下编译的

$ python -c 'import sys; from distutils.sysconfig import get_config_var; print(get_config_var("Py_ENABLE_SHARED"))'

返回1，但它应该返回0.

所以我从git https://github.com/pythonnet/pythonnet

下载了最新的dev-source

将它放入正确的文件夹后，我编辑了setup.py设置变量在执行

之后检查共享库为0

$ sudo python setup.py install

脚本安装成功且没有错误，我可以在我的python脚本中使用import clr。为确保一切正常运行，您可以运行：

$ python src/tests/runtests.py

Answer 2

以后参考，Pythonnet issue #119

解决了这个问题

添加...

defines.append("PYTHON_WITHOUT_ENABLE_SHARED")

...到setup.py，然后使用python setup.py install [options]进行安装，效果与answer相同。

python.net import clr抛出无效指针错误
