Python裂变创建包和导入库

Question

我是裂变新手，我创建了一个裂变函数，将一个元素插入到甲骨文中。因为它是python，所以我需要安装cx_oracle。我遵循了working with dependencies.上的文档页面，基本上我需要在一个包中提供一个requirements.txt文件、一个shell脚本和我的python代码，该包将由构建器部署。这里的问题是，包的状态为running，而不是successfull。我需要这方面的帮助，我找不到任何关于如何使用cx_oracle或任何其他依赖项部署python裂变的示例

下面是我的代码、需求文件、脚本和目录

import cx_Oracle

def main():
    try:
        sql = 'INSERT INTO MYTABLE(NID,CRT_DATE,INDICATOR) VALUES (0,SYSDATE,1)';
        con = cx_Oracle.connect('oracle/oracle@localhost/orcl',encoding="UTF-8", nencoding="UTF-8")
        cur = con.cursor()
        cur.execute(sql)
        cur.close()
        con.commit()
        return 'successfully inserted on db'
    except Exception as e:
        return str(e)

脚本：

#!/bin/sh
pip3 install -r ${SRC_PKG}/requirements.txt -t ${SRC_PKG} && cp -r ${SRC_PKG} ${DEPLOY_PKG}

文件夹结构（zip文件）

./insertintodb/requirements.txt
./insertintodb/__init__.py
./insertintodb/build.sh
./insertintodb/insert_into_db.py

这就是我得到的结果

>>fission pkg info --name insertintodb-zip-3cnd

我一开始就犯了这个错误

我注意到pod storagesvc被标记为挂起。因此，我使用values.yaml文件和Helm配置了一个存储类，从而使它能够运行。然后包最终成功构建，但现在我无法执行该函数

这是我的包输出

在裂变页面上的教程之后，我创建了入口点

fission fn create --name insertintodb --pkg insertintodb-zip-ttr2 --entrypoint "insertintodb.main"

然而，现在我尝试测试函数，我得到模块未找到错误

fission fn test --name insertintodb

这是错误跟踪。我是不是遗漏了什么
