Python 패키지 빌드가 성공했지만 패키지가 잘못 빌드되었습니다.

실행하면 python3 setup.py build다음과 같이 종료됩니다.

running install_lib
creating /usr/local/lib/python3.4/dist-packages/sklearn
error: could not create '/usr/local/lib/python3.4/dist-packages/sklearn': Permission denied

/usr/local/lib/물론 사용 하지 않기 때문에 쓸 수는 없습니다 sudo. 이 단계에서는 sudo를 사용하는 데 주의해야 합니다.

이 것이 마지막이다 sudo python3 setup.py install:

running install_egg_info
Writing /usr/local/lib/python3.4/dist-packages/scikit_learn-0.18.dev0.egg-info
running install_clib

나 한테보기 좋다. 그러나 시도하면 import sklearn다음 오류가 발생합니다.

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

python3 setup.py build으로 달려야 할까요 sudo?이것은 Kubuntu Linux 15.10에 있습니다.

Ubuntu 패키지 버전은 python-scikits-learnPython 2에서만 작동하므로 Python 3이 필요합니다.
