导入错误：无法从 AWS EC2 上的'psutil'导入名称'_psutil_linux'

Question

我在AWS上运行一个EC2实例，使用python包时出错。我已经使用pip安装了psutil和stanfordcorenlp，但当我尝试导入时，我收到了以下错误：

>>> from stanfordcorenlp import StanfordCoreNLP
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/ec2-user/maxio-efs/stanfordcorenlp/__init__.py", line 1, in <module>
from stanfordcorenlp.corenlp import StanfordCoreNLP
File "/home/ec2-user/maxio-efs/stanfordcorenlp/corenlp.py", line 14, in <module>
import psutil
File "/home/ec2-user/maxio-efs/psutil/__init__.py", line 99, in <module>
from . import _pslinux as _psplatform
File "/home/ec2-user/maxio-efs/psutil/_pslinux.py", line 26, in <module>
from . import _psutil_linux as cext
ImportError: cannot import name '_psutil_linux' from 'psutil' (/home/ec2-user/maxio-efs/psutil/__init__.py)

即使导入psutil似乎也不起的作用

>>> import psutil
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/ec2-user/maxio-efs/psutil/__init__.py", line 99, in <module>
from . import _pslinux as _psplatform
File "/home/ec2-user/maxio-efs/psutil/_pslinux.py", line 26, in <module>
from . import _psutil_linux as cext
ImportError: cannot import name '_psutil_linux' from 'psutil' (/home/ec2-user/maxio-efs/psutil/__init__.py)

我尝试过很多解决方案，包括安装python-devel。我该如何解决此问题？

Answer 1

我在错误的目录中执行代码。我安装了一个名为maxio-efs的EFS，其文件结构为：

SSH POINT/
maxio-efs/
stanfordcorenlp
psutil
(other python packages)

上述错误仅在从maxio-efs目录内的运行python脚本时发生。我需要在其他地方，以便python能够找到正确的包。通过从与maxio-efs相同的目录级别运行python脚本，问题消失了。
