InfluxDB：由于我的令牌和os.getenv，无法与客户联系

我只是从infuxdb开始。在UI上，Python有一个部分可以从数据库开始，其中一个示例：初始化客户端，写数据，提出请求并关闭客户端。为了验证您必须在UI上生成令牌的请求，该请求允许保护请求。但是，当我运行示例代码时，我会从我的代码的第12行中获得错误“只能连接str（不是“非型”）到str。

代码：

from datetime import datetime
import os

from influxdb_client import InfluxDBClient, Point, WritePrecision
from influxdb_client.client.write_api import SYNCHRONOUS

# You can generate an API token from the "API Tokens Tab" in the UI
token = os.getenv("INFLUX_TOKEN")
org = "XXXXXXX"
bucket = "XXXXXXX Bucket"

with InfluxDBClient(url="https://europe-west1-1.gcp.cloud2.influxdata.com", token=token, org=org) as client:

    write_api = client.write_api(write_options=SYNCHRONOUS)
    point = Point("mem") \
        .tag("host", "host1") \
        .field("used_percent", 23.43234543) \
        .time(datetime.utcnow(), WritePrecision.NS)

    write_api.write(bucket, org, point)
    
    query = """from(bucket: "XXXXXXX Bucket") |> range(start: -1h)"""
    tables = client.query_api().query(query, org=org)
    for table in tables:
        for record in table.records:
            print(record)
            
    client.close()

我知道问题来自OS.getEnv（“ influx_token”），因为它应该返回字符串，但实际上返回了非类型对象，但是我不知道为什么它不起作用。有了令牌，我得到了2件事：令牌的名称及其在创建时获得的代码。 I've tried :

os.getenv("the name of the token")
os.getenv("the code of the token")
same of 2 above but with ' instead of "

All the time the same error, so please if someone可以帮我！

I am just starting with InfluxDB.
On the UI there is a section for Python to start with the database with an example: initialize the client, write data, make a request and close the client. In order to authenticate the request you have to generate a token on the UI which allows to secure the request. But when I run the example code I get the error "can only concatenate str (not "NoneType") to str" from line 12 of my code.

The code :

from datetime import datetime
import os

from influxdb_client import InfluxDBClient, Point, WritePrecision
from influxdb_client.client.write_api import SYNCHRONOUS

# You can generate an API token from the "API Tokens Tab" in the UI
token = os.getenv("INFLUX_TOKEN")
org = "XXXXXXX"
bucket = "XXXXXXX Bucket"

with InfluxDBClient(url="https://europe-west1-1.gcp.cloud2.influxdata.com", token=token, org=org) as client:

    write_api = client.write_api(write_options=SYNCHRONOUS)
    point = Point("mem") \
        .tag("host", "host1") \
        .field("used_percent", 23.43234543) \
        .time(datetime.utcnow(), WritePrecision.NS)

    write_api.write(bucket, org, point)
    
    query = """from(bucket: "XXXXXXX Bucket") |> range(start: -1h)"""
    tables = client.query_api().query(query, org=org)
    for table in tables:
        for record in table.records:
            print(record)
            
    client.close()

I understand that the problem come from the os.getenv("INFLUX_TOKEN") because it's supposed to return a string but actually return NoneType object, but I dont know why it doesn't work. With the token I got 2 things : the name of the token and its code which I obtain when when it's created.
I've tried :
