mac安裝cx_Oracle 出現cannot locate an Oracle software錯誤解決辦法

前幾個步驟可參考這篇文章：http://www.cs.utexas.edu/~mitra/csSpring2011/cs327/cx_mac.html

 

在進行到sudo python setup.py build 以及install的時候

明明echo $ORACLE_HOME等這些環境變量都設置的，但還是報找不到ORACLE HOME的錯誤，錯誤如下：

userdeMacBook-Pro:cx_Oracle-5.1.2 mac$ sudo python setup.py build
Password:
Traceback (most recent call last):
  File "setup.py", line 132, in <module>
    raise DistutilsSetupError("cannot locate an Oracle software " \
distutils.errors.DistutilsSetupError: cannot locate an Oracle software installation
userdeMacBook-Pro:cx_Oracle-5.1.2 mac$ sudo echo $ORACLE_HOME
/Users/mac/oracle/instantclient_11_2

 根據提示找到setup.py文件的132行，寫的是

119 
120 # try to determine the Oracle home
121 #userOracleHome = os.environ.get("ORACLE_HOME")
122 userOracleHome="/Users/mac/oracle/instantclient_11_2"
123 if userOracleHome is not None:
124     if not CheckOracleHome(userOracleHome):
125         messageFormat = "Oracle home (%s) does not refer to an " \
126                 "9i, 10g or 11g installation."
127         raise DistutilsSetupError(messageFormat % userOracleHome)
128 else:
129     for path in os.environ["PATH"].split(os.pathsep):
130         if CheckOracleHome(path):
131             break
132     if oracleHome is None:
133         raise DistutilsSetupError("cannot locate an Oracle software " \
134                 "installation")

 找不到目錄就打出異常，程序退出，我這里在122行給他這個目錄強行寫死了（確保該目錄的確存在）

然后在執行安裝，程序順利通過。
