jupyter 安装但当我尝试运行时无法识别“jupyter”

问题描述 投票：0回答：2

我安装了 Jupyter Notebook，它报告满足要求，但当我尝试运行时，它报告“jupyter”未被识别为内部或外部命令。

我猜我缺少路径定义，但找不到 jupyter.exe。

我在 stackoverflow 上看到其他帖子说按照安装说明设置 python 库路径，但我搜索了 jupyter 安装并没有找到对此的引用。

有什么建议吗？

顺便说一句，Python 完全新手。

这是我尝试运行 jupyter 时的错误

c:\Users\john_\Documents>jupyter notebook
'jupyter' is not recognized as an internal or external command,
operable program or batch file.

这里我显示python已安装并且可以运行

c:\Users\john_\Documents>python
Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

检查python安装文件夹下的scripts文件夹中是否有名为jupyter的exe文件。如果是，则将脚本文件夹添加到路径中。 我建议你使用 python 的 anaconda 发行版。它会照顾一切。

今天，我也遇到了同样的错误：The term 'jupyter' is not recognize as the name of cmdlet, function, script file, or operable program,”所以经过一个巨大的过程，我成功解决了这个问题，并且现在它可以在我的系统中识别了，这是我解决这个问题的方法：

为了解决这个问题，我将引导您完成两种可能首先适合您的方法，但如果它不起作用，那么您可以检查第二种方法，它帮助我解决了我的问题。

第 1 步：验证 Jupyter 安装

pip list

在已安装的软件包列表中查找 

jupyter
。如果没有安装，您可以使用以下命令安装：

pip install jupyter

第 2 步：找到 Jupyter 可执行文件 如果已安装 Jupyter 但您仍然遇到错误，则意味着 

jupyter.exe
可执行文件丢失或不在您的 PATH 中。

方法一：本地Python安装

  1. 导航到Python脚本目录：转到Python的安装目录。例如：

    C:\Users\YourUsername\AppData\Local\Programs\Python\PythonXX\Scripts
    将 XX 替换为您的 Python 版本。

  2. 检查 

    jupyter.exe
    ：确保 
    jupyter.exe
    存在于 脚本目录。

  3. 添加到路径：

    • 打开开始搜索，输入 
      env
      ，然后选择 
      Edit the system environment variables
      。
    • 在系统属性窗口中，单击 
      Environment Variables
      按钮。
    • 在环境变量窗口中，在 
      Path
      部分找到 
      System variables
      变量，然后单击 
      Edit
      。
    • 点击“新建”，添加Scripts目录的路径
      C:\Users\YourUsername\AppData\Local\Programs\Python\PythonXX\Scripts
    • 单击“确定”关闭所有窗口并应用更改。

  4. 验证 Jupyter 命令：打开新终端并运行：

    jupyter --version

方法2：漫游Python安装 如果您的 Python 安装在 Roaming 目录中，请按照以下步骤操作：

  1. 导航到 Python 脚本目录：转到安装 Python 的目录。例如： 

    C:\Users\YourUsername\AppData\Roaming\Python\Python312\Scripts

  2. 检查 

    jupyter.exe
    ：确保 
    jupyter.exe
    存在于脚本目录中。

  3. 添加到路径：

    • 打开开始搜索，输入 
      env
      ，然后选择 
      Edit the system environment variables
      。
    • 在系统属性窗口中，单击 
      Environment Variables
      按钮。
    • 在环境变量窗口中，在 
      Path
      部分找到 
      System variables
      变量，然后单击 
      Edit
      。
    • 点击“新建”，添加Scripts目录的路径
      C:\Users\YourUsername\AppData\Local\Programs\Python\PythonXX\Scripts
    • 单击“确定”关闭所有窗口并应用更改。

  4. 验证 Jupyter 命令：打开新终端并运行：

    jupyter --version

按照以下步骤操作，您应该能够解决问题并成功使用 Jupyter 命令。
