Question

我试图用pip安装PyMongo Python包。 Ansible mongodb_user module需要它。

我正在使用以下Ansible脚本安装pip和pymongo：

- hosts: tag_Name_Development
  become: true
  remote_user: user
  tasks:
    - name: install python tools
      yum: name={{ item }} state=latest
      with_items:
        - gcc
        - python-devel
        - python-setuptools
        - python-pip

    - name: install pymongo
      pip: name=pymongo state=latest

    - name: add admin user to mongo
      mongodb_user:
        login_port: 27017
        database: admin
        name: admin
        password: "{{ mongodb.admin_pass }}"
        roles: userAdminAnyDatabase
        state: present

成功安装工具后，我得到了Ansible错误。

FAILED! => {"changed": false, "failed": true, "msg": "the python pymongo module is required"}

在安装了pymongo的服务器上，我得到了

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

其他相关信息pip freeze和pip list

$ python-pip freeze
backports.ssl-match-hostname==3.4.0.2
ordereddict==1.2
pymongo==3.3.0

$ python-pip list
backports.ssl-match-hostname (3.4.0.2)
ordereddict (1.2)
pip (6.1.1)
pymongo (3.3.0)
setuptools (12.2)

还有许多与此问题相关的问题，但这些都没有帮助。我没有安装bson，而且我没有使用任何虚拟环境。

Answer 1

原来我安装了两个版本的python（2.6和2.7）。即使默认值为2.7，我的Ansible脚本也会在2.6文件夹pymongo

下安装/usr/local/lib64/python2.6/site-packages

我发现通过运行$ python-pip show pymongo和$ python2.6 -c "import pymongo"可以正常工作。

我更改了我的Ansible脚本以安装python27-pip而不是python-pip，并且它开始运行良好。

Answer 2

我有类似的问题。我通过将PIP安装目录附加到PYTHON_PATH并更改PIP安装目录的权限来解决它。
