如何从 Ubuntu Linux 使用 pip 安装 cx_oracle 包？

我正在尝试使用 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，但似乎没有任何与此包关联的文件：https://pypi.python.org/pypi/cx_Oracle/5.1.2

这是否意味着我必须手动安装该包http://cx-oracle.sourceforge.net和外星人？

    ReadError: not a gzip file

答案1

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

要安装 cx_Oracle，您还需要 Oracle 的 instantclient。如果您想要一种简单的安装方式，我前段时间准备了一个包。python-cxoracle。

只需复制适用于你的 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
