如何使用python腳本安裝軟件包

Question

我想使用python腳本安裝軟件包。 我已經閱讀了關於PackageManager API的文檔（ http://doc.aldebaran.com/2-4/naoqi/core/packagemanager-api.html ）：

因此，我將應用程序與choregraphe打包在一起，如http://doc.aldebaran.com/2-4/naoqi/core/packagemanager.html中所述，並且我嘗試使用如下所示的python腳本進行安裝：

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)

這是我收到的錯誤消息：

# 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

我猜這是因為必須將軟件包上載到機器人上，並且軟件包文件路徑必須是機器人上的文件路徑。

已編輯

我已將軟件包添加到Choreographe空白項目中，並在機器人上運行了該空白項目。 這樣，包被保存到與路徑機器人/home/nao/.local/share/PackageManager/apps/.lastUploadedChoregrapheBehavior/test_package_handlers_01-835a92-1.0.0.pkg ，當我在我的腳本已經改變了路徑（ "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" ），腳本按預期工作並將軟件包安裝在機器人上。

因此，有一種方法可以從我的PC安裝軟件包而不將其上傳到機械手，因為否則最好使用Choregraphe上載項目。

對我要實現的目標給出以下解釋也許是一件好事：

• 我的PC上有一個文件夾，例如20個軟件包
• 我想用一個python腳本安裝所有這20個軟件包
• 像這樣調用時，有一個Python腳本會安裝文件夾中的所有軟件包： 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()

這段代碼ftp = ftplib.FTP(ROBOT_URL)引發以下異常：

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

同樣，當我使用用戶名“ nao”連接到機器人並按照http://doc.aldebaran.com/2-5/dev/tools/opennao.html中的說明傳遞“ nao”，然后嘗試在/home/nao/.local/share/PackageManager/apps/創建文件夾/home/nao/.local/share/PackageManager/apps/帶有sudo mkdir它通知我： Sorry, user nao is not allowed to execute '/bin/mkdir dasdas' as root on Pepper. 。 如果我僅使用mkdir ，這將告訴我： mkdir: cannot create directory 'new_folder': Permission denied

Answer 1

使用qibuild ，您還可以使用以下命令直接安裝：

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

Answer 2

您確實確實需要先上傳文件。 您可以使用scp或sftp來執行此操作。 將.pkg放置在機械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()
