jupyter contrib nbextension install 给出了 Jupyter 命令 `jupyter-contrib` not found

jupyter contrib nbextension install gives Jupyter command `jupyter-contrib` not found

尝试通过终端中的以下步骤(重新)安装 Jupyter 的 nbextension

  1. pip 安装jupyter_contrib_nbextensions
  2. jupyter contrib nbextension 安装 --user
  3. 安装 --user jupyter nbextension 启用 varInspector/main

第 1 步 = 运行,我可以通过终端中的“jupyter notebook”启动笔记本。

第 2 步 = 失败

因此,如果有人出于任何原因遇到与我相似的情况,可能是因为获得了一台新机器,并且 IT 施展了他们的巫术魔法,将我的旧东西转移到了这台新机器上。

总之,在我拿到新机器后,我还有很多东西需要安装,我无法准确地指出是什么导致了我的问题,但最终我能够解决。在下面跟我来...


检查我的(搜索)python.exe 文件,我发现(搜索返回)2 个路径,其中 python.exe 存在。第一个被添加为环境变量(添加到 windows 路径)

  1. C:\Users-----\AppData\Local\Programs\Python\Python310
  2. C:\Users----\AppData\Roaming\Python\Python310\

第二个未添加。将漫游版本添加到路径变量并没有解决问题,而是给出了额外的错误: Fatal error in launcher: Unable to create process using '"C:\Program Files\Python310\python.exe"


所以

  1. 我卸载了 python(之前卸载了它并没有帮助单独完成)

  2. 删除了所有指向python的环境变量(这里是为了以防万一的环境变量-https://www.computerhope.com/issues/ch000549.htm

  3. 已从 VS 代码中卸载 python 扩展 (https://marketplace.visualstudio.com/items?itemName=ms-python.python)

  4. 删除了上述两个路径中提到的Python个文件夹

  5. 然后重新安装python(在安装过程中单击添加到路径)

  6. 重新安装 VS 代码 python 扩展

  7. 现在一切正常。

祝你好运
