python - 导入错误 : No module named xgboost

Question

当我尝试从 python 终端导入时，我收到了这个错误，虽然我按照所有步骤安装 xgboost，但不知何故 python 无法获取包详细信息。我对 python 比较陌生，我可以轻松安装 numpy 和 pandas 包,我用这个链接在MACOSX上安装http://xgboost.readthedocs.io/en/latest/build.html

>>> import xgboost
   Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   ImportError: No module named xgboost

当我执行 pip install xgboost 时，我收到了这个错误，

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/h7/pyph_7qj6171tqp50cf2xc7m0000gn/T/pip-build-TEvbD6/xgboost/ 

我在打印系统路径上得到这个，

print sys.path

首先，您需要控制您的 python 环境。下载homebrew python 通过将这些粘贴到一个新的终端窗口中

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

在这里您将被提示输入您的密码。安装 homebrew 后，使用 brew install python 安装 python。请使用 brew doctor 检查您的安装并遵循 homebrew 的建议。

现在，使用全新的终端窗口，从 pip 安装 xgboost。打开terminal并将其粘贴到:

pip install xgboost
