Python 代碼在一台計算機上工作，但不在其他計算機上：“預期的 str、bytes 或 os.PathLike object，未列出”

Question

我正在運行此代碼以使用來自 GSUtils 的 subprocess 和 bq 命令從 Google Big Query 獲取表列表。 出於某種我不明白的原因，它在一台計算機上工作（Python 3.8.6），但在另一台計算機上（Python 3.8.7）我收到下面發布的錯誤。

代碼有什么問題？

謝謝！

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]

這是 python 拋出的錯誤：

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)
  File "C:\Python\lib\subprocess.py", line 489, in run
    with Popen(*popenargs, **kwargs) as process:

    args = list2cmdline(args)
  File "C:\Python\lib\subprocess.py", line 549, in list2cmdline
    for arg in map(os.fsdecode, seq):
  File "C:\Python\lib\os.py", line 818, in fsdecode
    filename = fspath(filename)  # Does type-checking of `filename`.
TypeError: expected str, bytes or os.PathLike object, not list

正如盧克伍德沃德所說，似乎參數是列表中的列表。 所以改變這一點，它對兩者都有效。 仍然不知道為什么它在一台計算機上工作......

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]
