Python 导入错误：没有名为“pymongo”的模块

ImportError: No module named 'pymongo'

提问by user3151858

I have a problem running pymongo on Win 7 (64) with Python 3.4, mongodb 4.2.10. The error output is as follows:

我在使用 Python 3.4、mongodb 4.2.10 在 Win 7 (64) 上运行 pymongo 时遇到问题。错误输出如下：

import pymongo
ImportError: No module named 'pymongo'

The code is pretty simple:

代码非常简单：

import pymongo
from pymongo import MongoClient

client=MongoClient()
db=client.test_db
dict={'A':[1,2,3,4,5,6]}
db.test_collection.insert(dict)
to_print=db.test_collection.find()
print(to_print)

I tried already re-installing Python and MongoDB - did not help. It works when I do it manually in cmd, i.e. mongod.exe and mongo.exe work fine. It appears there is problem with pymongo, but I don't know how to fix it.

我已经尝试重新安装 Python 和 MongoDB - 没有帮助。当我在 cmd 中手动执行它时它可以工作，即 mongod.exe 和 mongo.exe 工作正常。pymongo 似乎有问题，但我不知道如何解决。

All you need is to actually install pymongo(currently you just have mongo and python, but they do not know how to speak with each other). This page is telling you exactly what to do:

您所需要的只是实际安装pymongo（目前您只有 mongo 和 python，但它们不知道如何相互交谈）。这个页面告诉你具体该怎么做：

• go to pymongo page
• download and run installer.

• 转到pymongo 页面
• 下载并运行安装程序。

If you have installed pymongo using following command :

如果您使用以下命令安装了 pymongo：

sudo pip install pymongo or
sudo -E pip install pymongo 

And still you are getting import error then try to run your python script with sudo like :

您仍然遇到导入错误，然后尝试使用 sudo 运行您的 python 脚本，例如：

sudo python example.py

If you are able to run the script this way, but not without sudo. Then there can be a problem with PYTHON_PATH or Permission issue.

如果您能够以这种方式运行脚本，但不能没有 sudo。那么可能存在 PYTHON_PATH 或权限问题。

Solving isssue#1 (i.e. PYTHON_PATH) : Location where pip installs packages and location where python looks for packages do not match.

解决问题#1（即 PYTHON_PATH）：pip 安装包的位置和 python 查找包的位置不匹配。

So how do you find where pip install packages ? Run following command :

那么如何找到 pip 安装包的位置呢？运行以下命令：

sudo pip show pymongo

It shows output like this :

它显示如下输出：

---
Name: pymongo
Version: 3.4.0
Location: /usr/local/lib/python2.7/dist-packages

Now you know where pip install packages. Add following line in your .bashrc :

现在您知道 pip 安装包的位置了。在 .bashrc 中添加以下行：

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages/

Run following command to execute .bashrc again :

运行以下命令再次执行 .bashrc ：

source .bashrc

Now try to run python script without sudo. It should run.

现在尝试在没有 sudo 的情况下运行 python 脚本。它应该运行。

If not then do the following :

如果没有，请执行以下操作：

Solving issue#2 (i.e. Permission): Allow non-root users to read and execute python pacakages.

解决问题#2（即权限）：允许非 root 用户读取和执行 python pacakages。

sudo chmod -R ugo+rX /usr/local/lib/python2.7/

This should solve your all problems. You should be able to run python script without sudo.

这应该可以解决您的所有问题。您应该能够在没有 sudo 的情况下运行 python 脚本。

1. Make a new folder in your documents like "flask-pymongo"
2. In your terminal change directory to C:\Users\YOUR_USERNAME\Documents\Flask-PyMongo\
3. git clone https://github.com/dcrosta/flask-pymongo
4. cd flask-pymongo
5. py setup.py develop ORpython setup.py develop (depends how python was install to your path)
6. from anywhere in your terminal use : pip install pymongo

1. 在您的文档中创建一个新文件夹，例如“flask-pymongo”
2. 在您的终端将目录更改为 C:\Users\YOUR_USERNAME\Documents\Flask-PyMongo\
3. git 克隆https://github.com/dcrosta/flask-pymongo
4. cd 烧瓶-pymongo
5. py setup.py develop或python setup.py develop（取决于python如何安装到您的路径）
6. 从终端的任何地方使用：pip install pymongo

If you have a problem like that probably you didn't two things.

如果你有这样的问题，可能你没有做两件事。

1. you didn't install pymongo.You can install by below command;

   $pip install pymongo

2. You installed pymongo but You have two python packages location. like below;

   • C:\Python\Python37-32\Lib\site-packages\pymongo(pymongo installed here)

   • C:\Anaconda3\Lib\site-packages\"pymongo is not here"

   • And you try to work here.

   • Probably you run Spyder but Spyder is looking to Anaconda\Lib\site-packages\ but pymongo packages are not here.

1. 你没有安装pymongo。你可以通过下面的命令安装；

   $pip install pymongo

2. 您安装了 pymongo 但您有两个 python 包位置。如下图；

   • C:\Python\Python37-32\Lib\site-packages\pymongo（这里安装了pymongo）

   • C:\Anaconda3\Lib\site-packages\“pymongo 不在这里”

   • 而你尝试在这里工作。

   • 可能你运行 Spyder，但 Spyder 正在寻找 Anaconda\Lib\site-packages\ 但 pymongo 包不在这里。

Sorry for bad english.

I saw things like pip and setuptools but not pymongo. I clicked the '+' at the bottom of the pane and searched for pymongo and found it and could install it there. After adding this the project ran fine

我看到了 pip 和 setuptools 之类的东西，但没有看到 pymongo。我单击窗格底部的“+”并搜索 pymongo 并找到它并可以将其安装在那里。添加此项目后，该项目运行良好
