我的mac上安装了python27和python35 . 我为python27使用了别名python2，为python35使用了python . 在终端中输入“python”时，python35显示出来 . 我也有Anacoda . 通过对，我应该安装pip3和jupyter笔记本 .
我试图使用jupyter笔记本 . 我在终端输入“jupyter notebook”，我得到了
-bash: jupyter: command not found
我输入了python -m pip install jupyter
Requirement already satisfied: jupyter in /Users/xxv/anaconda/lib/python3.5/site-packages
然后我输入：pip3 install jupyter，根据我得到的文档
-bash: pip3: command not found
pip安装jupyter，我得到：
"/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -u -c "import setuptools, tokenize;__file__='/private/var/folders/vv/243h_5ks0xs0cmt62rx7swlm0000gn/T/pip-build-VsnCwB/MarkupSafe/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /var/folders/vv/243h_5ks0xs0cmt62rx7swlm0000gn/T/pip-Fa2r4V-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/var/folders/vv/243h_5ks0xs0cmt62rx7swlm0000gn/T/pip-build-VsnCwB/MarkupSafe/
pip show pip，得到：

您的活动PIP适用于python2.7
如果你有python3.5，pip就会自动出现 . 尝试，
python3 -m pip install jupyter使用python3的PIP正确安装jupyter .考虑更改你执行时触发的默认python和PIP版本 python or pip
您可以使用别名来执行上述操作，
