Question

当我按照MathWorks页面（https://de.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html）上的说明操作并想要运行命令时 import matlab.engine 发生以下错误：

enter code here

OSError: Please reinstall MATLAB Engine for Python or contact MathWorks Technical Support for assistance: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /usr/local/MATLAB/R2018a/extern/engines/python/dist/matlab/engine/glnxa64/../../../../../../../bin/glnxa64/libmwengine_api.so)

我还尝试重新安装Matlab引擎，并使用Mathworks（python setup.py install）中建议的命令代替以下命令：

python setup.py build --build-base=$(mktemp -d) install

我使用Python 3.5.2并安装了Ubuntu 16.04中的MATLAB R2018a。

有人有想法吗？

非常感谢你的帮助！

未找到GLIBCXX_3.4.22

您可以在{例如}中解压缩libstdc++.so.6 -> libstdc++.so.6.0.22。您的$ HOME，并在运行命令时包含它：示例→

export LD_LIBRARY_PATH=/home/[name]/libstdc++6_6.3.0_amd64:$LD_LIBRARY_PATH && import matlab.engine

什么是...... [命令]

[command]表示与$ HOME中的libstdc++.so.6一起使用的“任何命令”。

关于文件夹libstdc ++ 6_6.3.0_amd64 /：您可以重命名为例如lib64文件名较短：/ home / [name] / lib64 /→

export LD_LIBRARY_PATH=/home/[name]/lib64:$LD_LIBRARY_PATH && import matlab.engine

在Python中导入Matlab引擎：找不到OSError版本“GLIBCXX_3.4.22”
