導入cx_oracle的問題

我有一個使用cx_Oracle（在virtualenv中）的Python項目（運行在Ubuntu 12.04上）。當我運行這個項目時，我不會導入這個模塊。現在我想用主管來控制我的項目。當我開始從主管，開始崩潰項目和上升這個異常：導入cx_oracle的問題

File "/home/vagrant/scrapy/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 578, in spawn_worker 
    worker.init_process()

    self.callable = self.load() 
    File "/home/vagrant/scrapy/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 65, in load 
    return self.load_wsgiapp()

    import cx_Oracle 
ImportError: libclntsh.so.11.1: cannot open shared object file: No such file or directory

我跟着從this網站的說明，還this other網站。但我無法解決這個問題。

監督者的conf文件是：

[program:api_server] 
command = /home/vagrant/scrapy/bin/gunicorn api:app 
directory = /home/vagrant/scrapy/src/scrapy/scrapy_server/flask_server/ 
environment = PATH="/home/vagrant/scrapy/bin/python", ORACLE_HOME="/usr/lib/oracle/12.1/client64", LD_LIBRARY_PATH="/usr/lib/oracle/12.1/client64/lib" 
user = vagrant 
autostart=true 
autorestart=true 
stderr_logfile=/var/log/api.err.log 
stdout_logfile=/var/log/api.out.log 
redirect_stderr = True

缺少什麼我在這裏？如果您需要更多信息，請告訴我，我會更新此問題。

謝謝大家

您是否設置了所有必需的env變量（如$ ORACLE_HOME，...）？ –

是的，正如我寫的，我設置了所需的所有環境變量，如教程中所述（鏈接位於上方）。如果我手動啓動它，項目運行完好 – Sam

如果您正在使用Oracle即時客戶端，沒有設置環境變量ORACLE_HOME。您只需要設置LD_LIBRARY_PATH以包含libclntsh.so的位置。

從環境變量中，您使用的是版本爲12.1的Oracle Instant Client，但cx_Oracle本身似乎是使用11.2編譯的。這將需要糾正。您需要確保cx_Oracle是使用12.1編譯的，或者您需要使用新的cx_Oracle 6.0b1，它可以自動在不同的Oracle客戶端版本之間自動切換。

的確是關於使用12.1而不是11.2（杜，我忽略了它）。按照您的建議，我將測試Oracle而不設置ORACLE_HOME。謝謝你的幫助！ – Sam
