如何使用python脚本安装软件包

Question

我想使用python脚本安装软件包。 我已经阅读了关于PackageManager API的文档（ http://doc.aldebaran.com/2-4/naoqi/core/packagemanager-api.html ）：

因此，我将应用程序与choregraphe打包在一起，如http://doc.aldebaran.com/2-4/naoqi/core/packagemanager.html中所述，并且我尝试使用如下所示的python脚本进行安装：

import qi
import sys


if __name__ == '__main__':
    ip = "11.1.11.111"
    port = 9559

    session = qi.Session()
    try:
        session.connect("tcp://" + ip + ":" + str(port))
    except RuntimeError:
        print ("Can't connect to Naoqi at ip \"" + ip + "\" on port " + str(port))
        sys.exit(1)

    service = session.service("PackageManager")

    package = "C:\\test_package_handlers_01-835a92-1.0.0.pkg"

    # this is to see if the problem is that python can not locate the file
    with open(package) as f:
        print f

    service.install(package)

这是我收到的错误消息：

# provided package could be opened
<open file 'C:\\test_package_handlers_01-835a92-1.0.0.pkg', mode 'r' at 0x02886288>
Traceback (most recent call last):
  File "C:/test.py", line 24, in <module>
    service.install(package)
RuntimeError: C:\test_package_handlers_01-835a92-1.0.0.pkg: no such file

我猜这是因为必须将软件包上载到机器人上，并且软件包文件路径必须是机器人上的文件路径。

已编辑

我已将软件包添加到Choreographe空白项目中，并在机器人上运行了该空白项目。 这样，包被保存到与路径机器人/home/nao/.local/share/PackageManager/apps/.lastUploadedChoregrapheBehavior/test_package_handlers_01-835a92-1.0.0.pkg ，当我在我的脚本已经改变了路径（ "C:\\\\test_package_handlers_01-835a92-1.0.0.pkg"和"/home/nao/.local/share/PackageManager/apps/.lastUploadedChoregrapheBehavior/test_package_handlers_01-835a92-1.0.0.pkg" ），脚本按预期工作并将软件包安装在机器人上。

因此，有一种方法可以从我的PC安装软件包而不将其上传到机械手，因为否则最好使用Choregraphe上载项目。

对我要实现的目标给出以下解释也许是一件好事：

• 我的PC上有一个文件夹，例如20个软件包
• 我想用一个python脚本安装所有这20个软件包
• 像这样调用时，有一个Python脚本会安装文件夹中的所有软件包： python package_installer.py path_to_packages_folder

import qi
import ftplib
import os

ROBOT_URL = "10.80.129.90"

print "Uploading PKG"
pkg_file = "my-application-0.0.1.pkg"
pkg_path = os.path.join(os.path.dirname(os.path.abspath(__file__)), pkg_file)

ftp = ftplib.FTP(ROBOT_URL)
ftp.login("nao", "nao")
with open(pkg_path) as pkg:
    ftp.storbinary("STOR "+pkg_file, pkg)

print "Connecting NAOqi session"
app = qi.Application(url='tcp://'+ROBOT_URL+':9559')
app.start()
session = app.session

print "Installing app"
packagemgr = session.service("PackageManager")
packagemgr.install("/home/nao/"+pkg_file)

print "Cleaning robot"
ftp.delete(pkg_file)
ftp.quit()

print "End"
app.stop()

这段代码ftp = ftplib.FTP(ROBOT_URL)引发以下异常：

Traceback (most recent call last):
  File "C:/Stefan/DSK_PEPPER_clode_2/PythonScripts/_local_testing/uploading_and_installing_package.py", line 11, in <module>
    ftp = ftplib.FTP(ROBOT_URL)
  File "C:\Python27\lib\ftplib.py", line 120, in __init__
    self.connect(host)
  File "C:\Python27\lib\ftplib.py", line 135, in connect
    self.sock = socket.create_connection((self.host, self.port), self.timeout)
  File "C:\Python27\lib\socket.py", line 575, in create_connection
    raise err
socket.error: [Errno 10061] No connection could be made because the target machine actively refused it

同样，当我使用用户名“ nao”连接到机器人并按照http://doc.aldebaran.com/2-5/dev/tools/opennao.html中的说明传递“ nao”，然后尝试在/home/nao/.local/share/PackageManager/apps/创建文件夹/home/nao/.local/share/PackageManager/apps/带有sudo mkdir它通知我： Sorry, user nao is not allowed to execute '/bin/mkdir dasdas' as root on Pepper. 。 如果我仅使用mkdir ，这将告诉我： mkdir: cannot create directory 'new_folder': Permission denied

Answer 1

使用qibuild ，您还可以使用以下命令直接安装：

qipkg deploy-package /path/to/my-package.pkg --url nao@10.10.23.45

Answer 2

您确实确实需要先上传文件。 您可以使用scp或sftp来执行此操作。 将.pkg放置在机械PackageManager.install后，即可使用PackageManager.install 。

想象一下：

import qi
import paramiko
import os

ROBOT_URL = "10.80.129.90"

print "Uploading PKG"
pkg_file = "my-application-0.0.1.pkg"
pkg_path = os.path.join(os.path.dirname(os.path.abspath(__file__)), pkg_file)

transport = paramiko.Transport((ROBOT_URL, 22))
transport.connect(username="nao", password="nao")
sftp = paramiko.SFTPClient.from_transport(transport)
sftp.put(pkg_path, pkg_file)

print "Connecting NAOqi session"
app = qi.Application(url='tcp://'+ROBOT_URL+':9559')
app.start()
session = app.session

print "Installing app"
packagemgr = session.service("PackageManager")
packagemgr.install("/home/nao/"+pkg_file)

print "Cleaning robot"
sftp.remove(pkg_file)
sftp.close()
transport.close()

print "End"
app.stop()
