Python 代码在一台计算机上工作，但不在其他计算机上：“预期的 str、bytes 或 os.PathLike object，未列出”

Question

我正在运行此代码以使用来自 GSUtils 的 subprocess 和 bq 命令从 Google Big Query 获取表列表。 出于某种我不明白的原因，它在一台计算机上工作（Python 3.8.6），但在另一台计算机上（Python 3.8.7）我收到下面发布的错误。

代码有什么问题？

谢谢！

import subprocess
import re


params=[]
params.append("--use_legacy_sql=false ")
params.append(r"SELECT table_name FROM Exportar_CSV.INFORMATION_SCHEMA.TABLES WHERE table_schema IN ('Exportar_CSV')")
process = subprocess.run(['bq','query',params], shell=True, capture_output=True)
output = process.stdout.decode("utf-8")
#Convert the output to a list type.
table_list=output.split("\r\n")
table_list=[item.strip("|").strip() for item in table_list]
table_list= [ item for item in table_list if "table_name" not in item and "+--------" not in item and '' != item]

这是 python 抛出的错误：

Traceback (most recent call last):
  File "Export_to_CSV.py", line 8, in <module>
    process = subprocess.run(['bq','query',params], shell=True, capture_output=True)

正如卢克伍德沃德所说，似乎参数是列表中的列表。 所以改变这一点，它对两者都有效。 仍然不知道为什么它在一台计算机上工作......

params=[]
params.append(str("bq"))
params.append(str("query"))
params.append(str("--use_legacy_sql=false"))
params.append(str(r"SELECT table_name FROM Exportar_CSV.INFORMATION_SCHEMA.TABLES WHERE table_schema IN ('Exportar_CSV')"))
process = subprocess.run(params, shell=True, capture_output=True)
output = process.stdout.decode("utf-8")
#Convert the output to a list type.
table_list=output.split("\r\n")
table_list=[item.strip("|").strip() for item in table_list]
table_list= [ item for item in table_list if "table_name" not in item and "+--------" not in item and '' != item]
