🤖 AI解决方案
python: can't open file '/data/pubmed-search/NO_DELETE/pubmed_if_ISSN.py': [Errno 2] No such file or directory
python: 无法打开文件 '/data/pubmed-search/NO_DELETE/pubmed_if_ISSN.py': [Errno 2] 没有那个文件或目录原因分析：
执行命令时，Python 解释器找不到指定的脚本文件 pubmed_if_ISSN.py。
解决方案：
请确认 pubmed_if_ISSN.py 文件确实存在于 /data/pubmed-search/NO_DELETE/ 目录下，并检查文件名是否拼写正确。如果文件不存在，请将其上传到该路径。
预防措施：
- 在执行命令前，增加一个步骤来验证脚本文件的存在。
- 使用绝对路径执行脚本，或者确保工作目录设置正确，以避免路径问题。
