Ubuntu 使用pip安装cx\U oracle时出现非法指令错误

我已经在Ubuntu上安装了Oracle Instant Client 11.2.0.4，并且已经设置了Oracle环境变量，SQL*Plus正在运行，但是运行命令“pip install cx_Oracle”失败

完整的错误消息是：

如何解决这个问题？

我的python是3.5，系统是ubuntu，oracle是11.2.0.4 instant clienti可以在我的ubuntuLooks上成功使用sqlplus，就像你的gcc安装而不是cx_oracle有问题一样；检查你是否有当前版本的gcc以及相关的工具和库。我在新安装的Fedora.M时遇到了类似的错误请确保您安装了devel工具。不确定它是否与ubuntu的名称相同，但在Fedora上我安装了dnf python devel python3 devel libevent develalex poole是正确的，我重新安装了gcc，现在它可以运行了

  cx_Oracle.c:595:1: internal compiler error: Illegal Instruction
