所以我收到了一个FileNotFoundError: [Errno 2] No such file or directory error
,我真的不知道该怎么办,因为文件肯定在那里。当我尝试在命令heroku run "otree resetdb"
之后使用heroku和git部署oTree实验时,会发生错误。操作系统是Windows10
完整错误消息:

FileNotFoundError: [Errno 2] No such file or directory: 'D:\\Experiment\\oTreeproject\\oTreeonlineshop-master\\shop\\oTree\\experimentMusic\\products.json'
我还尝试了一个带有普通斜杠和双反斜杠的代码版本,但仍然收到了相同的错误。接下来,我尝试使用pathlib中的路径重写models.py
中的路径,如下所示:
from pathlib import Path
with open(Path('D:/Experiment/oTreeproject/oTreeonlineshop-master/shop/oTree/experimentMusic/products.json'), 'r', encoding='utf-8') as jsonfile:
data=jsonfile.read()
shoppinglist = json.loads(data)
它也不起作用,有类似的错误消息
有什么问题吗?文件products.json在那里,并且不是空的,所以我不知道为什么它不工作。我还试着在我的笔记本电脑上运行这个实验,它工作得非常好,所以我想问题在于heroku上的部署。欢迎任何建议,非常感谢
最好的, 丽娜
我想出来了。解决方案是将
.json
文件的路径重写为相对路径(而不是绝对路径)相关问题 更多 >
