這段時(shí)間在弄機(jī)器學(xué)習(xí)的事情，然后看Macbook里面的Python庫(kù)有點(diǎn)舊，就用pip更新一下恬试。
$ pip install --upgrade numpy
結(jié)果拋出下面這個(gè)異常報(bào)告

Google后找到這個(gè)解決方案
$ pip install --upgrade pip
$ sudo pip install numpy --upgrade --ignore-installed
$ sudo pip install scipy --upgrade --ignore-installed
$ sudo pip install scikit-learn --upgrade --ignore-installed
