安裝環(huán)境

mac環(huán)境：MacBook Pro (Retina, 13-inch, Mid 2014)，參見文章Jupyter Notebooks 入門，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

多次重試無效。

網(wǎng)上搜索錯誤“Could not find a version that satisfies the requirement jupyter”，有很多文章，沒有按文章重試。

改用如下命令：

xxx-laptop:~ xxx$ pip3 install jupyter

結(jié)果：

You are using pip version 9.0.3, however version 20.1.1 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

這里的提示很重要，成功在此

xxx-laptop:~ xxx$ pip3 install --upgrade pip

升級PIP后，再次pip install jupyter

完成后，執(zhí)行jupyter：

jupyter

usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir]

? ? ? ? ? ? ? [--paths] [--json]

? ? ? ? ? ? ? [subcommand]

...

成功。

如果不能自動打開瀏覽器：

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，重啟就可以了。

在輸入框中按tab，會出現(xiàn)提示
