运行 aws s3 cp 时子进程出错：[Errno 2] 没有这样的文件或目录：'aws'

Question

我能够从命令行成功执行此命令，并将所需的 csv 复制到 s3 存储桶aws s3 cp /Users/kaswani/tips.csv s3://dplearn/

但是，当我尝试使用子进程从 python 中运行相同的内容时，它会抛出错误： subprocess.check_output subprocess.check_output(['aws','s3','cp','/Users/kaswani/tips.csv','s3://dplearn/'])

错误：

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/Users/kaswani/anaconda/envs/aws/lib/python3.5/subprocess.py", line 626, in check_output
    **kwargs).stdout
  File "/Users/kaswani/anaconda/envs/aws/lib/python3.5/subprocess.py", line 693, in run
    with Popen(*popenargs, **kwargs) as process:
  File "/Users/kaswani/anaconda/envs/aws/lib/python3.5/subprocess.py", line 947, in __init__
    restore_signals, start_new_session)
  File "/Users/kaswani/anaconda/envs/aws/lib/python3.5/subprocess.py", line 1551, in _execute_child
    raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'aws'

我一直无法调试它。 Subprocess 适用于 ls 等基本命令

使用，shell=True 是可行的，即 subprocess.check_output(['aws','s3','cp','/Users/kaswani/tips.csv','s3://dplearn/'], shell=真的）
