我正在尝试创建一个Alexa技能，告诉我下一班火车时间何时在我的火车站。我想使用一个名为pygtfs的软件包，它是一个模拟以谷歌通用公共交换Feed规范（GTFS）格式存储的信息的库。我有处理从alexa发送的json对象的文件，它们工作正常。我无法将zip部署包上传到aws lambda。我有一个python脚本，创建一个部署包，但我收到一个错误。该错误不会将正确的文件添加到部署包中。
def _copy_deployment_files(deployment_dir):
for deployment_file in deployment_files:
if os.path.exists(deployment_file):
cmd = "cp{0}{1}".format(deployment_file, deployment_dir).split()
--->return_code = subprocess.call(cmd, shell=False)<----
else:
raise NameError("Deployment file not found [{0}]".format(deployment_file))
在_copy_deployment_files函数中尝试使子进程方法shell参数为true
return_code = subprocess.call(cmd, shell=True)
但它不包含AlexaBaseHandler.py，AlexaDeploymentHandler.py和main.py.
我的问题是如何让create_development将AlexaBaseHandler.py，AlexaDeploymentHandler.py和main.py添加到部署包中，以及如何确保pygtfs包也安装到部署包中？< /强>
以下是return_code = subprocess.call（cmd，shell = True）

Attribution: I wish I could remember where I found this on the

Create a zip archive from a directory.
Note that this function is designed to put files in the zip archive with
either no parent directory or just one parent directory, so it will trim any
leading directories in the filesystem paths and not include them inside the
zip archive paths. This is generally the case when you want to just take a
directory and make it into a zip file that can be extracted in different
locations.
Keyword arguments:
dirPath -- string path to the directory to archive. This is the only
required argument. It can be absolute or relative, but only one or zero
leading directories will be included in the zip archive.
zipFilePath -- string path to the output zip file. This can be an absolute
or relative path. If the zip file already exists, it will be updated. If
not, it will be created. If you want to replace it from scratch, delete it
prior to calling this function. (default is computed as dirPath + ".zip")
includeDirInZip -- boolean indicating whether the top level directory should
be included in the archive or omitted. (default True)

NVM我想通了。我复制的代码是使用cp作为子进程的复制命令。我查找了操作系统的命令（Windows 10），它是COPY而不是cp。这是对子进程的新调用cmd = "COPY {0}
