Pycharm同时看到和不看到json文件

Question

我想运行以下代码将 json 文件放入我的 ubuntu 18.04 虚拟机上的 elasticsearch 中：

import requests, json, os
from elasticsearch import Elasticsearch

directory = '/home/mk/my_json_files/'

res = requests.get('http://localhost:9200')
print (res.content)
es = Elasticsearch([{'host': 'localhost', 'port': '9200'}])

i = 1

print(os.listdir(directory))

for filename in os.listdir(directory):
    if filename.endswith(".json"):
        f = open(filename)
        docket_content = f.read()
        # Send the data into es
        es.index(index='myindex', ignore=400, doc_type='docket', id=i, body=json.loads(docket_content))
        i = i + 1

但不幸的是，当我运行它时，它显示了一个错误：

b'{\n  "name" : "mk-VirtualBox",\n  "cluster_name" : "elasticsearch",\n  "cluster_uuid" : "Xs1ITjiaRcWCo35qDBNvOA",\n  "version" : {\n    "number" : "7.10.1",\n    "build_flavor" : "default",\n    "build_type" : "deb",\n    "build_hash" : "1c34507e66d7db1211f66f3513706fdf548736aa",\n    "build_date" : "2020-12-05T01:00:33.671820Z",\n    "build_snapshot" : false,\n    "lucene_version" : "8.7.0",\n    "minimum_wire_compatibility_version" : "6.8.0",\n    "minimum_index_compatibility_version" : "6.0.0-beta1"\n  },\n  "tagline" : "You Know, for Search"\n}\n'
['stocks_data.json']
Traceback (most recent call last):
  File "/home/mk/PycharmProjects/importing_json_files_into_elasticsearch/importing_json_files.py", line 16, in <module>
    f = open(filename)
FileNotFoundError: [Errno 2] No such file or directory: 'stocks_data.json'

奇怪的是，在第二行它告诉我他找到了我的带有股票值的 json 文件。但他无法打开它。我用

更改了python文件和json文件的属性

chmod 777 file_name

但这没有帮助。
