python3.6和3.7_jupyter与多个版本的python 3(3.6和3.7)选择了错误的站点包

我一直在我的 table 上敲我的头3天,我不知道该怎么办这个问题,所以如果你知道发生了什么,请告诉我 .

Issue: 当我运行全局安装(在虚拟环境之外)jupyter笔记本时,注册内核(ipykernel安装在虚拟环境中),其中虚拟环境的python3 -V为3.6.4,全局python3 -V为3.7 .0,当我激活venv内核时,jupyter笔记本(从活动的venv运行)崩溃,因为它试图从全局python 3.7.0中获取站点包

从上面的几行可以看出,它调用了错误的站点包:

这是我的设置:

pyenv用于管理python的多个版本

pipenv for virtualenvs(对这个还不是很满意)

我如何设置:

安装全局python(我不喜欢用我的默认python的pyenv搞乱,我保持最新版本)

> brew install python3 # This install 3.7.0

安装pyenv

> brew install pyenv

安装python 3.6.4(我需要这个用于tensorflow)

> pyenv install 3.6.4

安装pipenv(我这里没有使用pip安装程序)

> brew install pipenv

创建一个项目(我有一个WORKON_HOME设置,所以我的.venvs在我的〜/ .venvs中创建)

> cd Projects

> mkdire test_project

> cd test_project

> pipenv --python 3.6.4 #create the virtual env

启动虚拟环境

> pipenv shell

> python3 -V

> Python 3.6.4 # I have validated in another shell that global is still 3.7

> pyenv which python3

> /Users/cap/.pyenv/versions/3.6.4/bin/python3

安装ipykernel并进行设置

> pipenv install ipykernel

> ipython kernel install --user --name=lastresort-yyl8tfk8 --display-name "Python (lastresort-yyl8tfk8)"

检查jupyter是否看到新内核(注意:我还在静脉中)

> jupyter kernelspec list

> lastresort-yyl8tfk8 /Users/cap/Library/Jupyter/kernels/lastresort-yyl8tfk8

运行jupyter笔记本并选择内核

jotebook运行正常,但当我进入并选择Python(lastresort-yyl8tfk8)时,内核重新启动以加载lastresort-yyl8tfk8内核,我从上面得到错误,它与3.7中的site-packages混淆 .

我尝试了许多带路径的东西 . 我甚至还使用了ipython配置文件更改,例如:iptyhon profile virtual env

我真的需要一些帮助,至少有一个如何解决这个问题的方向......

我的最终目标很简单:

能够有多个版本的python和相应的ipykernels,我可以在jupyter安装全局的jupyter注册后从虚拟环境中运行它们 . 通过这种方式,我可以将我的代码和笔记本保存在他们的项目文件夹中,包含venvs . 实际上这很简单,我只是不知道我搞砸了什么 .

Thank you all in advance!

UPDATE: 我刚刚确认,如果我删除全局jupyter笔记本并将其安装在venv中,它可以正常工作 . 我没想到它,但仍然 .

UPDATE: 这似乎是一些PYTHONPATH恶作剧,但我不知道如何解决它 .

UPDATE: 试图按照注释中的建议使用python -m运行,但它产生了相同的结果 . 出于某种原因,当我使用激活的虚拟环境(在ipython中正确设置python3.6)调用jupyter笔记本(安装在虚拟环境之外)时,它不会调用正确的3.6站点包 .

我见过很多人使用该设置 . 我真的不知道从哪里开始 .
