Python 尝试使用google云运行BigQuery示例，但遇到问题

我试图在python中使用BigQuery来运行一个示例，但我一直收到相同的错误。它表示通过在终端中写入以下内容来设置路径（在pycharm中）：

我的路径是： C:\Users\Ejer\PycharmProjects\pythonProject\my json file.json的名称

不知道我的问题是什么

输入：

from google.cloud import bigquery

# Construct a BigQuery client object.
client = bigquery.Client()

query = """
    SELECT name, SUM(number) as total_people
    FROM `bigquery-public-data.usa_names.usa_1910_2013`
    WHERE state = 'TX'
    GROUP BY name, state
    ORDER BY total_people DESC
    LIMIT 20
"""
query_job = client.query(query)  # Make an API request.

print("The query data:")
for row in query_job:
    # Row values can be accessed by field name or index.
    print("name={}, count={}".format(row[0], row["total_people"]))

输出：

请务必包含以下代码，它对我有效

import os
SERVICE_ACCOUNT_FILE='<enter your_json file here>'

## for example 
## SERVICE_ACCOUNT_FILE='adh_client.json'

os.environ["GOOGLE_APPLICATION_CREDENTIALS"]=SERVICE_ACCOUNT_FILE

导入操作系统
服务\帐户\文件=“”
##比如说
##服务\u帐户\u文件='adh\u client.json'
os.environ[“谷歌应用程序凭据”]=服务帐户文件

尝试以下工作示例

from dateutil.parser import parse
from google.cloud import bigquery

stream_query = """create table `proj.dataset.YOUR_NEW_TABLE4`  partition                                                                              by date(_time) as SELECT * FROM `proj.dataset.YOUR_NEW_TABLE1` WHERE 1=                                                                             2"""

stream_client = bigquery.Client()

stream_Q = stream_client.query(stream_query)
stream_data_df = stream_Q.to_dataframe()

谢谢。但这似乎是一个新的错误：google.api_core.exceptions.Forbidden:403 POST:Access Denied:Project ace-sight-299913:用户没有在Project ace-sight-299913中的bigquery.jobs.create权限。你有一个正确的服务帐户文件，即“google_应用程序_凭据”吗？是的，我创建了一个，如示例所示。奇怪…请参考此链接谢谢。但这似乎是一个新的错误：google.api_core.exceptions.Forbidden:403 POST:Access Denied:Project ace-sight-299913:User没有bigquery.jobs.create在Project ace-sight-299913中的权限。您是否有一个正确的服务帐户文件，即“google_应用程序_凭据”？是的，我创建了一个作为前有足够的显示。奇怪…请参考此链接
