How to fix a bug that jupyter notebook does not start automatically

I couldn't find a page that explains the target method of the jupyter automatic startup bug for beginners, so I summarized it.

As usual in the terminal trying to launch jupyter

jupyter notebook

If you enter

Unable to recognize the "open location" message.(-1708)

The phenomenon that the error message is displayed for a while. You can deal with it by directly hitting the displayed URL, but other measures at the moment are summarized.

(Hereafter when using Chrome)

1. How to add code to ".bash / profile"

First, check the file (this step is not necessary, but just in case)

cd

And move to your home directory at the terminal

ls -al

If you check the files in your home directory including special files in

 .bash_profile

There should be! So I'm going to add some code to this file.

Open the file with a suitable text editor and it's OK. Open Finder, in the folder of your home directory, Show hidden files using "command + shift +." Open ".bash_profile" using a text editor or the like.

This time, I opened it with Atom.

At the end of this file

export BROWSER=/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome

To add.

And save. You will be prompted for the administrator's name and password.

Save it, restart your terminal and launch Jupyter and the bug should be fixed: blush:

If you are using zsh instead of bash, you can rewrite ".zshrc" in the same way.

2. How to add code to "~ / .jupyter / jupyter_notebook_config.py" [Additional notes]

Then, just in case another method. At the terminal

cd

Finally, move to your home directory.

cd ./.jupyter

Go to the folder ".jupyter" with

ls -al

Check the files in the folder with. If you have "jupyter_notebook_config.py", it's OK. If not, I will make it.

How to make it in the terminal

jupyter notebook --generate-config

Just hit.

Now that you have "jupyter_notebook_config.py", edit it!

Open Finder and display hidden files with "command + shift +.". Since there is "jupyter_notebook_config.py" in the folder ".jupyter", open it with a text editor etc. in the same way as method 1.

Just add the following line to this file and you're good to go!

c.NotebookApp.browser = u'chrome'

It's like this. Save it, restart your terminal and launch Jupyter and the bug should be fixed: blush:

[Addition] If this doesn't help, try the following line instead (I didn't start up automatically again, and I was back in the following line)

c.NotebookApp.browser = u'open -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome %s'

By the way, if you want to specify it in safari,

c.NotebookApp.browser = u'Safari'

It will be.

There was also a post saying that an error message was displayed when "Google Chrome" was used instead of "chrome". Also, in the case of safari, there was a post saying that "u'Safari" was useless and that it was fixed with "'Safari'". https://github.com/jupyter/notebook/issues/2438#issuecomment-301736816
