python - pip install fail：终端列出最近的软件包安装尝试，不会安装软件包

Question

为了通过 Jupyter notebook 和 Python 访问和运行 Matlab 代码，我尝试按照博客的建议安装“matlab_kernal”（带有错字）和“matlab_kernel”，但我没有意识到我需要 MatLab，而不是 MatLab 编译器运行时。

我收到错误消息：“收集 matlab_kernal 找不到满足 matlab_kernal 要求的版本（来自版本：）找不到 matlab_kernal 的匹配分布”

作为一种解决方法，我在 GitHub 上找到了计算我想要的指标的 python 代码，但作者说我需要从“mpi4py”安装“MPI”。

但是，我的终端现在似乎停留在我之前的“matlab_kernal”安装尝试上。它列出了我之前安装这些软件包的尝试（请参阅所附屏幕截图中红色错误消息上方的所有白色文本）。

我正在运行：来自 /anaconda3/lib/python3.7/site-packages/pip 的 pip 18.1（python 3.7）

我试过了：

• 点卸载“包”
• 终端重启
• 笔记本电脑重启

Answer 1

请用：

pip install matlab-kernel

也可以尝试conda：

 conda install -c pchrapka matlab_kernel 

我认为您在使用kernal.

我py3.7继续pip v19.3。

输出：

$ pip install matlab-kernel
