`jupyter notebook` 在 cmd win 10 中抛出 `jupyter` 无法识别错误

我从 stackoverflow 移走了这个问题，因为据说这个堆栈更合适

我在离线模式下使用 Python 3.8。也就是说，如果我需要安装某个包，我会去下载它package.whl或package.tar.gz使用 进行安装pip install package.whl。有一次我想安装 jupyter notebook，它需要安装一堆其他包。我耐心地安装了所有必要的包。最后，我有以下跟踪：

我想 ”现在它可以工作了“但我错了，jupyter notebook终端中的命令抛出了： 'jupyter' is not recognized as an internal or external command, operable program or batch file.

为了找到解决方案，我谷歌了一下，发现要么使用 Anaconda，要么在我的C:\py38\脚本路径（并且该确切路径应添加到系统变量中）。但我jupyter.exe那里没有，但我已经添加了C:\py38\脚本到上面提到的地方。我不愿意使用 Anaconda（这是另一个故事），对于后期，文件夹中有这些文件：

我尝试重新启动电脑，但无济于事。

有人能帮忙吗？谢谢

编辑：我不知道jupyter-notebook应该做什么但是当我输入它时cmd它会抛出以下内容：

jupyter-notebook

答案1

所以我找到了一个与 Python 3.8 和 Jupyter 相关的问题。我执行了上述所有步骤，但都没有奏效。

time.clock() 函数自 Python 3.3 起就被弃用了，现已被移除：请根据您的需求使用 time.perf_counter() 或 time.process_time() 来获得明确定义的行为。（由 Matthias Bussonnier 在 bpo-36895 中贡献。）

它来自这里，我降级到 python 3.7 并且它可以工作。

答案2

100% 有效的解决方案：
这是由于“环境变量”

按着这些次序：

  1. 打开下载“python-3.8.2-amd64.exe”安装程序或任何其他版本的python包的文件夹
  2. 双击“python-3.8.2-amd64.exe”
  3. 点击“修改”
  4. 您将看到“可选功能”
  5. 点击下一步”
  6. 选择“将python添加到环境变量”
  7. 点击“安装”

然后，您可以在所需的任何文件夹中运行 jupyter，
例如打开“cmd”命令提示符并输入：

E:
E:> jupyter notebook

它将启动而不显示

Jupyter' 无法被识别

答案3

以下命令对我有用：
在命令提示符下，运行

  1. pip install notebook
  2. jupyter notebook

答案4

我发现 jupyter notebook 并没有安装在我认为的位置，因此我的环境变量需要更新。我找到了 jupyter.exe 文件C:\Users\<NAME OF USER>\AppData\Roaming\Python\Python38\scripts。一旦我将其添加到我的环境变量中，我就可以运行 jupyter notebook 命令。我还将其添加C:\Users\<NAME OF USER>\AppData\Roaming\Python\Python38\site-packages到我的 EVs 中，以防有任何依赖项。
