安裝環(huán)境
mac環(huán)境：MacBook Pro (Retina, 13-inch, Mid 2014)，參見(jiàn)文章Jupyter Notebooks 入門(mén)黄伊，按此文安裝
操作如下：
xxx-laptop:~ xxx$python3 -m pip install --upgrade pip
xxx-laptop:~ xxx$ python3 -m pip install jupyter
結(jié)果如下：
Collecting jupyter
? Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x1023cdc50>: Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known',)': /simple/jupyter/

? Could not find a version that satisfies the requirement jupyter (from versions: )
No matching distribution found for jupyter
多次重試無(wú)效。
網(wǎng)上搜索錯(cuò)誤“Could not find a version that satisfies the requirement jupyter”通孽，有很多文章妇智，沒(méi)有按文章重試。
改用如下命令：
xxx-laptop:~ xxx$ pip3 install jupyter
結(jié)果：

完成后，執(zhí)行jupyter：
jupyter
usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir]
? ? ? ? ? ? ? [--paths] [--json]

成功黍少。
如果不能自動(dòng)打開(kāi)瀏覽器：
xxx-laptop:~ xxx$ jupyter notebook --generate-config
xxx-laptop:~ xxx$ cd .jupyter/
修改jupyter_notebook_config.py
c.NotebookApp.browser = u'chrome'
c.NotebookApp.notebook_dir = '/Users/xxx/workspace/jupyter'
c.NotebookApp.open_browser = True
保存寡夹，重啟就可以了。
在輸入框中按tab厂置，會(huì)出現(xiàn)提示
