build script error

[peterhenryfirst]

Hi,

When I try to build the project, I received an error from the scripts/build.sh file in line:

${venvdir}/bin/python2.7 ${venvdir}/bin/pip install --download-cache=${pipdir} pex requests

I changed to the pip install option:

--cache-dir

And build process finished correctly.

Should be your pip version is too old? My current version of python is 2.7.13 and pip version is 9.0.1

I do not know if the build script is correct or not.

Thanks @peterhenryfirst, I can confirm --download-cache seems to no longer exist as a flag for pip, at least for my version: 8.1.2. I'm guessing it existed earlier in this tool's development. My pip version throws no error about it, however.

Out of curiosity, could you provide the error you get?

I'll update the flag to use --cache-dir in an upcoming release, for now I suggest you do the workaround you mention. Thanks!

Hi @timvaillancourt,

Of course, this is the log when I execute the build script:

Thanks @peterhenryfirst, I suppose Pip 9.x throws the error you see for this while Pip 8.x (what we've tested on) ignores the error.

This fix will be in 1.0.2. Thanks!

[timvaillancourt]

This fix is available in this branch until release: https://github.com/Percona-Lab/mongodb_consistent_backup/tree/1.0.2

[peterhenryfirst]

Hi @timvaillancourt,

The fix works perfectly!

Could I close the issue?

Thanks.

[timvaillancourt]

Great, closing this one.
