Python packaged as an executable file

1

At first I uploaded the Run.exe file packaged on Windows directly to Linux and thought it could be used directly. But./run after the error. Baidu later know that theprogram on Windows can not run on Linux

Linux under the executable can be a suffix does not have a relationship, only with permissions, relying on the permissions of the file itself. Want to execute chmod 755 filename Change file permissions

Windows and Linux binaries can not be compatible, landlord check bar, you can not run Windows under Linux programs. Be sure to run under Linux and need to install wine

Linux default support ELF format binary files, Windows PE format can not run.

2 python after packaging with Pyinstaller, run the program error "pkg_resources. Distributionnotfound "solution

Pkg_resources. Distributionnotfound:the "Apscheduler" distribution is not found ....

Here obviously has packed the EXE file, also did not error. But when running the EXE, but the interface pops up and flashed through.

After reviewing the official documents of Pyinstaller , we found a solution .

Create a hook-ctypes.macholib.py file under the target file directory:

The contents are as follows:

#-*-Coding:utf-8-*-

From PyInstaller.utils.hooks import Copy_metadata

Datas = Copy_metadata (' Apscheduler ')

Then, when packing, add a--additional-hooks-dir=, as follows:

Pyinstaller-f yourfile.py--additional-hooks-dir=

After this modification, the package of EXE files will be able to use the normal.

3 APScheduler:LookupError:No Trigger by the name "interval" was found

Environment

python:2.6.6

pyinstaller:2.1
Apscheduler: It started with 3.0.1, then 3.0.5 .

Question One

Problem description

A Python program (python2.7)that was previously developed on another machine, running the Times wrong on a new machine

" interval " was found

Program code

ImportOS, time fromDatetimeImportdatetime fromApscheduler.schedulers.backgroundImportBackgroundschedulerdefmyjob ():Print('myjob:%s'%DateTime.Now ()) Time.sleep (5)if __name__=='__main__': Scheduler=Backgroundscheduler () scheduler.add_job (Myjob,'interval', Seconds=1) Scheduler.start ()Try:         whileTrue:time.sleep (5)    except(Keyboardinterrupt, Systemexit): Scheduler.shutdown ()

Reason

is due to the low version of Setuptools causing

Solutions

sudo pip install----ignore-installed Apscheduler

Then run the above Python code again to solve the problem.

Question Two

Problem description

When the first problem is resolved, an error is generated when you run an executable file that uses Pyinstaller packaging

Traceback (most recent): File"<string>", line 11,inch<module>File". ../out00-pyz.pyz/apscheduler.schedulers.base", line 330,inchadd_job File". ../out00-pyz.pyz/apscheduler.schedulers.base", Line 782,inch_create_trigger File". ../out00-pyz.pyz/apscheduler.schedulers.base", line 766,inch_create_plugin_instancelookuperror:no trigger by the name"interval"was found

Reason

It feels as if Pyinstaller was using the wrong version of Apschedulerwhen it was packaged. (not sure)???

Solutions

Do not use "' Interval ', Seconds=1" in the Add_job method to do trigger, but first create a Intervaltrigger object, and then Use this object when Add_job, namely:

Modify the original code

    ' interval ', Seconds=1)

For

    Trigger = Intervaltrigger (Seconds=1)    scheduler.add_job (myjob, Trigger)

The complete code is as follows

defmyjob ():Print('myjob:%s'%DateTime.Now ()) Time.sleep (5)if __name__=='__main__': Scheduler=Backgroundscheduler () trigger= Intervaltrigger (Seconds=1) Scheduler.add_job (myjob, Trigger) Scheduler.start ()Try:         whileTrue:time.sleep (5)    except(Keyboardinterrupt, Systemexit): Scheduler.shutdown ()

Then re-package with Pyinstaller, at this time to run the executable file will not be an error.

Focus: Because of the use of Intervaltrigger, so need to import from the package, and then I find such a post http://blog.csdn.net/mx472756841/article/details/51751616

Use the following code in this

#Sample Code     fromApscheduler.triggers.intervalImportIngervaltrigger#using string MethodsScheduler.add_job (Interval_tick,'interval', seconds=4,minutes=2, start_date=datetime.now () +dt.timedelta (seconds=120), end_date=datetime.now () +dt.timedelta (seconds=360))    #use Intervaltrigger to specify time to runTrigger = Intervaltrigger (seconds=60, start_date=datetime.now () +dt.timedelta (seconds=60), end_date=datetime.now () + Dt.timedelta (seconds=120) ) Scheduler.add_job (Date_tick, Trigger)

But his import here is wrong. I found a half-day, and later used in Python's own user graphical interface in the import Apschedluer after using DIR () step-by-step to find the correct name, and then run through.

4 you need to connect to the local database (MySQL on XAMPP) after packaging the executable file

At the same time is also to solve Navicat error : 1130-host. is not allowed to connect to this MYSQL server,mysql does not allow remote access from The method (http://www.cnblogs.com/shyy/archive/2012/03/30/2453034.html) to ask.

You can enter the shell after the operation (if the host is the% number, then all hosts can log on, including the remote host .)

Musql-uroot

Select Host,password,user,from User;

Update user Set host = "%" where host = "127.0.0.1"

5 greenlet.h:8:20: Fatal error: Python.h: No file or directory

The workaround is to install Python-dev, which is the Python header file and the static library package:

sudo apt-get install Python-dev

But it's still not working, TODO.
