Python正在忽略子进程

我有一个flask应用程序，用户上传一个文件并输入文本，然后将文本传输回flask应用程序，并用于为“适当”程序执行linux命令

以下是相关代码：

repoName = request.form['repoName']
completePath = packageDir + filename

subprocess.call(["aptly", "repo", "add", repoName, completePath])

当我返回

repoName

或

completePath

时，它返回正确的信息，但是subprocess.call被完全忽略，我不知道为什么。没有错误/回溯，除了apache从

命令中恰当地返回一个关于正确使用的日志外，如下所示：

Usage: aptly repo add <name> <package file.deb>|<directory> ...

aptly repo add - add packages to local repository


Options:
  -architectures="": list of architectures to consider during (comma-separated), default         to all available
  -config="": location of configuration file (default locations are /etc/aptly.conf, ~/.aptly.conf)
  -dep-follow-all-variants=false: when processing dependencies, follow a & b if depdency is 'a|b'
  -dep-follow-recommends=false: when processing dependencies, follow Recommends
  -dep-follow-source=false: when processing dependencies, follow from binary to Source packages
  -dep-follow-suggests=false: when processing dependencies, follow Suggests
  -remove-files=false: remove files that have been imported successfully into repository

出于某种原因，这很好…
您可以打印
completePath
的值吗。也许你需要使用
os.path.join（packageDir，filename）
来确保使用了正确的路径分隔符。是的，在packageDir上这样做，使用packageDir+filename会给我“/var/www/aptlyapp/app/tmp/vlc_2.0.3-5_amd64.deb”所以我不认为这是问题。在调用子流程之前，我通常会记录完整的命令。它通常有助于调试。什么是完整的命令<代码>'.join（[“恰当”、“repo”、“add”、repoName、completePath]）

完整命令是“恰当地repo add repoName completePath”或恰当地repo add“name”“file”。你说的.join是什么意思？只要有可以在终端中使用的实际字符串。联接将使用“”从列表中创建字符串，并在每个列表项之间使用分隔符。
