我想問一下，如果有一個例外的名字try: except:的錯誤No such file or directory。
例如：
try:
subprocess.run(["bash", my_path "start.sh"], shell=False)
except NoDirectory:
print('Error: This directory was not found. Please make sure the path is correct')
或者有沒有辦法subprocess.run從那里獲取錯誤代碼并從那里檢查它？

使用stderr=subprocess.PIPE引數以便您可以檢查錯誤輸出。
import subprocess
r = subprocess.run(['bash', '/some/nonexistent/path.sh'], stderr=subprocess.PIPE)
if r.returncode:
if b'No such file or directory' in r.stderr:
print('That file was not found.')

我無法bash在您的代碼中捕獲例外，正如它所寫的那樣。但是您可以嘗試以下代碼，即使它更長。您還可以發送一組命令，而不是一次發送一個命令：
注意- 在 Ubuntu 20.04 上測驗，使用 Python 3.8
commands = ("bash start.sh", "date",)
for c in commands:
p = subprocess.Popen(shlex.split(c), stdin=subprocess.PIPE, stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
output, error = p.communicate()
rc = p.returncode
if rc != 0:
if error.find(b"No such file or directory"):
print("Error: This directory was not found. Please make sure the path is correct")
else:
print(error.decode().strip())
else:
print(output.decode().strip())
輸出：
Error: This directory was not found. Please make sure the path is correct

如果有人想出如何No such file or directory從bash使用subprocess.
