ipython3 和 jupyter notebook 不允许 python3 选项答案

【问题标题】：ipython3 and jupyter notebook not allowing python3 opitionipython3 和 jupyter notebook 不允许 python3 选项

【问题描述】：

好的，我知道在无法解决此问题后我可能会收到一票否决票，但我对 python 和 jupyter notebook 还很陌生。到目前为止，我只能在初始设置时将 python3 与 jupyter notebook 一起使用，从那时起它就违背了所有逻辑，尽管 ipython 是 jupyter notebook 的后端，但它不再像某些渐进式那样支持 python2 并且什么都不想不再使用 pyhton2； python2 像斯大林格勒的俄罗斯人一样被放在我的笔记本上，我担心我可能无法将布尔什维克赶出去。

所以，我就像一个好孩子一样，制作了自己的 venv 环境并尝试为 python3 安装 ipython [你知道 - 根据他们的网站，唯一重要的版本]：

    main@McCarter:~/Desktop
    $ sudo python3 -m venv /Documents/Intro-to-Pandas
    main@McCarter:~/Desktop
    $ source /Documents/Intro-to-Pandas/bin/activate
    (Intro-to-Pandas) main@McCarter:~/Desktop
    $ python3 -m pip --version
    pip 9.0.1 from /Documents/Intro-to-Pandas/lib/python3.5/site-packages (python 3.5)
    (Intro-to-Pandas) main@McCarter:~/Desktop
    $ python3 -m pip install ipykernel

之后我收到错误，我将其归结为安装龙卷风的问题。所以我尝试使用 pip 和 sudo apt install 安装龙卷风。我什至尝试安装臭名昭著的 anaconda，我确信他们的开发者程序会以他们的软件破坏所有路径并类似于曼哈顿项目的设置而感到自豪：

我知道这与龙卷风有关。

我知道我可能必须购买一台新计算机，并且可能在安装 anaconda 后搬到另一个州才能使其正常工作。

我还 sudo apt install'd python-dev 和 buildessentials。仍然没有帮助。

我只是想知道为什么它不起作用 - 只是为了不知道。

【问题讨论】：

所以没什么哈哈？我应该重新安装所有东西[以自己的方式真的有点搞砸了

标签： python python-3.x jupyter-notebook

【解决方案1】：

我解决了我的问题。

/* Create a python3 virtual enviroment and then using jupyter notebook.*/
$ sudo python3 -m pip install virtualenv :
$ virtualenv mypythonAMCO : //create
$ source mypython/bin/activate : //activate
$ pip install jupyter : //install jupyter
/*Whenever you would like to stop the Jupyter Notebook process, press CTRL+C, type    Y when prompted, and then hit ENTER to confirm.*/

我卸载了 anaconda 并按照上述操作，创建了一个 virtualenv python 环境，以隔离我的“编码区域”，只有我希望运行和实现的文件/模块和 python 版本。制作 python 虚拟环境非常有帮助，因为它可以让您获得更多控制权。我能够使用带有“python3强调”的pip来安装pandas并启动jupyter notebook。
