通过.ebextensions安装pip软件包

Question

我无法通过ebextensions安装软件包psycopg2。

00_software.config

packages:
  yum:
    git: []
    htop: []
  pip:
    psycopg2: []

01_setup_pg_activity.config

commands:
    clone:
        command: git clone https://github.com/dalibo/pg_activity.git
    install_psycopg2:
        command: cd pg_activity && python setup.py install

或者，我也尝试了这个，但无济于事

commands:
    clone:
        command: git clone https://github.com/dalibo/pg_activity.git
    install_psycopg2:
        command: pip install psycopg2
    install_psycopg2:
        command: cd pg_activity && python setup.py install

将安装其他软件，但不会安装pip软件包

Traceback (most recent call last):
  File "/usr/local/bin/pg_activity", line 4, in <module>
    __import__('pkg_resources').run_script('pg-activity==1.6.1', 'pg_activity')
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 742, in run_script
    self.require(requires)[0].run_script(script_name, ns)
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 1510, in run_script
    exec(script_code, namespace, namespace)
  File "/usr/local/lib/python2.7/site-packages/pg_activity-1.6.1-py2.7.egg/EGG-INFO/scripts/pg_activity", line 42, in <module>

ImportError: No module named psycopg2

我必须手动进入并运行sudo pip install psycopg2才能正确安装。如何在构建过程中执行此操作？

将EB与AL2配合使用（python env；尚未在RoR上进行测试），已成功安装 pg_activity。

对于我拥有的软件包（仅显示psycopg2）

packages: 
    yum:
        python-psycopg2: []

[commands配置文件是（20_setup_pg_activity.config）：

commands:
    05_clone:
        command: git clone https://github.com/dalibo/pg_activity.git    
    10_install_pg_activity:
        command: cd pg_activity && python setup.py install

在完成环境设置后，我登录到EB实例以检查pg_activity是否存在（仅显示部分）：

ec2-user@ip-172-31-82-127 ~]$ pg_activity --help
Usage: pg_activity [options]

htop like application for PostgreSQL server activity monitoring.

Options:
  --version             show program's version number and exit
  -U USERNAME, --username=USERNAME
