python - pymongo ImportError 尽管已安装

Question

我正试图让 pymongo 在我们的 linux 服务器上运行，但是有些东西失败了，但我不知道是什么。

我在本地机器 (OsX) 上运行相同的设置

我按照建议使用 pip 安装了 pymongo:

$ sudo pip install pymongo

Cleaning up...

因此您认为 pymongo 已安装，但 Python 无法识别它:

$ python -c "import pymongo"

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

同样在 python 本身中:

$ python
Python 2.7.9 (default, Nov  3 2015, 14:21:40) 
[GCC 4.9.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymongo
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named pymongo
>>> exit()

有人知道吗？我的 mac 上没有这个问题

$ python -V
Python 2.7.9

尝试从源码安装:

$ git clone https://github.com/mongodb/mongo-python-driver.git pymongo
$ cd pymongo/
$ python setup.py install

不要忘记它的依赖:

sudo apt-get install build-essential python-dev
