Question

我必须将psycopg安装到旧的python（2.4）。一切正常，除了设置环境变量 - ＆gt; LD_LIBRARY_PATH。

- name: install psycopg
  shell: "{{ item }}"
    environment:
      CPPFLAGS: "-I/my_python/lib/python2.4/site-packages/mx/DateTime/mxDateTime"
      LD_LIBRARY_PATH: "/path_to_postgresql/lib"
  args:
    chdir: "/path_to_psycopg_src/"
  with_items:
    - ./configure --prefix=/my_python --with-python=/my_python/bin/python --with-postgres-libraries=/path_to_postgresql/lib --with-postgres-includes=/path_postgresql/include --with-mxdatetime-includes=/my_python/lib/python2.4/site-packages/mx/DateTime/mxDateTime
    - make
    - make install

成功安装后，我收到以下错误：

>>> import psycopg
    ImportError: libpq.so.4: cannot open shared object file: No such file or directory

当我手动导出时，它可以正常工作：

export LD_LIBRARY_PATH="/path_postgresql/lib"
>>> import psycopg
>>> psycopg
<module 'psycopg' from '/my_python/lib/python2.4/site-packages/psycopgmodule.so'>

因为您只为LD_LIBRARY_PATH任务设置了install psycopg。如果你想设置一个环境变量，不仅仅是为了任务/剧本，我想你需要编辑/etc/environment

Ansible playbook，设置环境变量不起作用
