我感觉是python路径的问题。我的python路径是：

which python3 # /usr/bin/python3

我的VPS中没有${PYTHONPATH}这个系统变量：

echo ${PYTHONPATH} # NULL

请问大佬，我应该如何改正？

项目名称来源，群友 @ Sngxpro 提供：

代号：琉璃（Liuli）

英文：RuriElysion
 or：RuriWorld

slogan：琉璃开净界，薜荔启禅关 ---梅尧臣《缑山子晋祠 会善寺》

寓意：构建一方净土如东方琉璃净世界。《药师经》云：「然彼佛土，一向清净，无有女人，亦无恶趣，及苦音声。」

目前打算写一个脚本，通过全文获取API来去获取全文，在根据自定义的格式寄给我的gmail...这样除了newsletter之外，一些RSS订阅和微信公众号都可以直接在spark阅读...

然而我找到的全文获取的付费api要求有些高，RSS里面的link格式不行，就算经过decodeURIComponent函数转换也还是格式不正确。

如果RSS订阅有原始网页的连接，就可以抓取用原始链接来获取全文而不会出错！

希望作者可以给与支持！感谢：）

截取一部分生成的RSS信息如下，此处的 updated 日期，为liuli在周期性运行的过程中更新时的时间，即使对于一条很久以前的RSS信息，它的 updated 也会被更新到当前时间。

这样会引起一些问题，在某些RSS订阅器上（如Tiny Tiny RSS），其时间轴上是根据 updated 来排序，而并非 published，如此一来，无法有效地区分当前的RSS哪些内容是最近生成的，哪些又是以前生成过的。

所以希望保留 updated 的时间不变（如第一次存到mongodb中时，记录当前时间；若周期性更新时则不改变其值）或者与 published 保持一致。

最后，希望我已经清楚地表达了我的问题和请求，谢谢！

参考的https://mp.weixin.qq.com/s/rxoq97YodwtAdTqKntuwMA 刚起了demo试着爬一下微信公众号的内容，但是日志里显示执行失败了。

Loading .env environment variables...

文章里给你docker compose配置文件里使用的liuli schedule镜像版本是不带playwright的，我看文章里提供的default的json里描述的使用playwright爬取微信内容，尝试着更改为了带playwright的版本，也显示执行失败。

测试脚本如下：

from src.collector.wechat_feddd.start import WeiXinSpider
WeiXinSpider.request_config = {"RETRIES": 3, "DELAY": 5, "TIMEOUT": 20}
WeiXinSpider.start_urls = ['https://mp.weixin.qq.com/s/OrCRVCZ8cGOLRf5p5avHOg']
WeiXinSpider.start()

错误原因： 数据清洗时，期望的数据格式是 2022-03-21 20:59，但实际抓取回来的数据是 2022-03-22 20:37:12，导致 clean_doc_ts函数报错。如下图

新增两个配置项：

# 企业微信分发用户（填写用户帐号，不区分大小写），多个用户用;分割
CC_WECOM_TO_USER=""
# 企业微信分发部门（填写部门名称），多个部门用;分割
CC_WECOM_PARTY=""

如两项都不填写，默认向当前应用所有部门的所有用户分发，如用户填写，则按用户填写的配置进行分发

如果按照教程手动添加pro.env文件，无法启动docker，但是如果不手动添加文件，启动docker的话会自动创建pro.env文件夹，然后docker会循环输出如下日志 Loading .env environment variables...
