Command "install update" interrupted with error: FileExistsError : [Errno 17] File exists:

[Carli Smith]

Hello,

I was trying to install an update for madgraph but it wasn't working and giving me this error:

Command "install update" interrupted with error:
TypeError : cannot use a string pattern on a bytes-like object
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.

which I fixed by editing the madgraph_interface.py file. I changed "text = filetext.read()" to "text = filetext.read().decode()" which was a solution I found from another error report. But now when I fun the update again it runs for a second but then gives me this:

Command "install update" interrupted with error:
FileExistsError : [Errno 17] File exists: '/Users/carlisavannah/Desktop/DarkMatterProject/MG5_aMC_v2_8_0/UPDATE_TMP'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.

Not sure what this means so if I could get some help that would be great! Thanks!

Hi,

You can do a
"rm -rf /Users/carlisavannah/Desktop/DarkMatterProject/MG5_aMC_v2_8_0/UPDATE_TMP"

Then for doing the update, the best from 2.8.0 is to do that when using python2.
if you run
pythonn2.7 ./bin/mg5
and then do the "install update" yous should avoid all those python3 issue.

Cheers,

Olivier

So I tried that rm -rf command that you suggested, then after trying to install the update in Python 2 it gave me the same "FileExistsError" as before except the issue was with a different file: MG5_aMC_v2_8_0/Template/LO

So I did the same thing "rm -rf /Users/carlisavannah/Desktop/DarkMatterProject/MG5_aMC_v2_8_0/Template/LO" and going back into Madgraph. However, when going back into it with the command ./bin/mg5_aMC I get this error:

FileNotFoundError: [Errno 2] No such file or directory: '/Users/carlisavannah/Desktop/DarkMatterProject/MG5_aMC_v2_8_0/Template/LO/Source/.make_opts'

I also can't get back into MadGraph using Python 2 either, it says "ImportError: No module named cPickle"

So maybe I accidentally deleted some necessary files, if that's the case I'm not sure how I'd get them back. Maybe I should just uninstall and then reinstall MadGraph and start fresh? Not sure.

HI,

Indeed removing Template/LO is not a good idea. and the only solution is to proceed with a fresh installation now.
Sorry for that,

Olivier
