I want to write a python script to call 'brew update' daily in my Mac. The below is the python script and launch plist.
#!/usr/local/bin/python import subprocess # update homebrew and check outdated package subprocess.call(["brew", "update"]) subprocess.call(["brew", "outdated"]) subprocess.call(["brew", "doctor"]) .plist
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>chancy.daily</string> <key>ProgramArguments</key> <array> <string>/usr/local/bin/python</string> <string>/Users/wuchangxi/Workspace/scripts/jobs/daily.py</string> </array> <key>StandardErrorPath</key> <string>/usr/local/var/log/chancy.daily.log</string> <key>StandardOutputPath</key> <string>/usr/local/var/log/chancy.daily.log</string> <key>StartCalendarInterval</key> <dict> <key>Minute</key> <integer>42</integer> <key>Hour</key> <integer>12</integer> </dict> </dict> </plist> When i run using the launchd load the plist file, there is the same error as below:
Traceback (most recent call last): File "/Users/wuchangxi/Workspace/scripts/jobs/daily.py", line 5, in <module> subprocess.call(["brew", "update"]) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 522, in call return Popen(*popenargs, **kwargs).wait() File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 710, in __init__ errread, errwrite) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1335, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory If run the python script directly in shell, it works well. But when call in the .plist, there is No such file error.
