如何修复安装 Jupyter Notebook 时出现的错误？

Question

我是 Python 新手，尝试在 Windows 命令提示符窗口中安装 Jupyter Notebook：

pip install jupyter

但是下载几分钟后，会显示如下错误信息：

  Installing build dependencies ... done
  Getting requirements to build wheel ... done
    Preparing wheel metadata ... error

我在这里只附上了错误输出的最后一部分。

如何解决此错误以成功安装 Jupyter Notebook？

EDIT1：我从错误消息中的链接安装了 Rust 包。之后我再次尝试安装 Jupyter Notebook，这一次在比之前更进一步的步骤之后，它输出了另一个错误：

Answer 1

做

pip install wheel

然后再试一次。它对我有用。

Answer 2

先升级你的点子：

pip install --upgrade pip

然后：

pip install jupyter

Answer 3

在 32-bit python 3.8.3 执行时未能安装 notebook 后，我到达了这篇文章。据我发现，pywinpty 是一个依赖项，不支持 32 位 执行（参见下面的来源）。

我通过在 64 位版本上安装 python 解决了这个问题。

来源：

How do I determine if my python shell is executing in 32bit or 64bit?

pip install fails on Python 3.8 32-bit, prevents Jupyter install #129

We can't generate 32 bit wheels, sorry. Please use a 64bit build of Python.

不是我的情况，但在使用 python 3.8 64-bit 时可能会对这个类似的问题有用

Answer 4

尝试使用 Anaconda。安装 conda 的链接https://www.anaconda.com/products/individual 然后 cmd ： conda install numpy cmd：康达安装jupyter cmd : jupyter 笔记本

Answer 5

错误信息看起来很清楚，你需要通过https://rustup.rs/安装Cargo
