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

【问题标题】：pip install fail: Terminal lists most recent attempts of package installation, won't install packagespip install fail：终端列出最近的软件包安装尝试，不会安装软件包
【发布时间】：2019-11-15 04:29:39
【问题描述】：

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： "收集 matlab_kernal 找不到满足 matlab_kernal 要求的版本（来自版本：）未找到 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”安装尝试中。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 (python 3.7) 的 pip 18.1

我试过了：

pip 卸载“包”
终端重启
笔记本电脑重启

标签： python matlab api terminal

【解决方案1】：

请使用：

pip install matlab-kernel

也可以试试conda：

 conda install -c pchrapka matlab_kernel

我认为你在使用 kernal 打错字。

我在py3.7 和pip v19.3 上。

输出：

$ pip install matlab-kernel

【讨论】：

感谢您的捕获，但即使我尝试使用正确拼写或完全不同的软件包安装软件包，我仍然收到“matlab_kernal”错误。查看我提供的图像，它列出了所有以前的安装尝试。
@GeoStephanieRae 一些依赖于 matlab-kernel 的包可能拼写错误
是的，我尝试使用正确拼写的内核进行安装，我也尝试安装其他软件包，但任何安装尝试都会出错。不管我尝试安装什么包，结果都是一样的；终端列出了以前的安装尝试（使用各种软件包）和错误：“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 的匹配分发”

【解决方案2】：

这是 pip 和 MacOS 的版本问题

See this thread

来自命令 'pip install 'package-name' 的 MacOS 终端错误： “收集‘包名’ 找不到满足“包名”要求的版本（来自版本：）没有找到“包名”的匹配分布”

在终端中卸载 pip 并重新安装 pip
