如何从 Ubuntu linux 使用 pip 安装 cx_oracle 包？

Question

我正在尝试使用 Ubuntu 从 Ubuntu 安装 cx_oracle，pip install cx_oracle但是出现以下错误。还尝试转到 pip 包页面，但看起来没有与此包关联的任何文件：https : //pypi.python.org/pypi/cx_Oracle/5.1.2

这是否意味着我必须使用 Alien从http://cx-oracle.sourceforge.net手动安装软件包？

    ReadError: not a gzip file

Answer 1

似乎自动下载的文件已损坏。这就是为什么ReadError: not a zip file

要安装 cx_Oracle，您还需要来自 Oracle 的即时客户端。如果你想要一个简单的安装方法，我前段时间准备了一个包python-cxoracle。

只需复制 Ubuntu 版本的文件并将 Instantclient 添加到 ld.so.conf

wget https://github.com/ozanturksever/python-cxoracle/archive/master.zip
unzip master.zip
cp -r python-cxoracle-master/12.04/* /
echo "/opt/instantclient_11_2" > /etc/ld.so.conf.d/oracleclient.conf
ldconfig
