Sanity check failed: loading fake module failed: 'Changing environment as dictated by module failed: invalid syntax

[kylecook80]

I am trying to install the 'intel' toolchain with the following command

eb intel-2015b.eb --robot

The installation attempts to install flex, however it failed with the error in the title of the issue. Below is the entire log from the build. Any suggestions?

I believe this is caused by this line:

eval `/opt/lmod/lmod/settarg/settarg_cmd -s python --destroy`;

That's not valid Python code, and EasyBuild is trying to execute it as Python code, since it's expecting output in Python syntax from Lmod.

This is caused by having the settarg module loaded, this has come up before. Are you trying this in a VM you got during SC15? :-)

@rtmclay: Is there any way to solve this on the Lmod side (this is not an EasyBuild problem imho). This has come up before.

@kylecook80: Try unloading the settarg module, and then trying again. Also, if you want to play with the Intel tools, you'll need to manually provide the install files to EasyBuild, since it won't be able to download them. Maybe go with the foss/2015b toolchain instead, which is all open-source software that EasyBuild should be able to download automagically.

@boegel I am trying this in a VM because of SC15! :)

This worked! Thank you so much.

Glad to hear that fixed your problem, I'll try to figure out how we can avoid this from happening when the settarg module is loaded.

@rtmclay: can you remind me why this invalid Python code pops up when settarg is loaded?

[boegel]

@rtmclay: ping?

Because Lmod defines the module command to be:

% type module module () {         eval $($LMOD_CMD bash "$@")         [ $? = 0 ] && eval $(${LMOD_SETTARG_CMD:-:} -s sh) }

And some how your code is picking this up.  When the settarg module is loaded, it defines LMOD_SETTARG_CMD to point to the settarg program.  When the settarg module is unloaded it needs to run a command as shown from tjhe settarg modulefile:

local cmd     = "eval " .. settarg_cmd .. " -s " .. myShell .. " --destroy" execute{cmd=cmd, modeA = {"unload"}}

Lmod always emits the execute command on unload.  I plan on changing it to only do so when the shell is bash or csh.  But that won't help EB as it use bash or csh as the shell passed to the module command.  AFAIK.

No, EasyBuild uses python as shell.

It doesn't use the module function, but calls the lmod binary directly as lmod python <subcommand>.

See https://github.com/hpcugent/easybuild-framework/blob/6b798c86938f3898454f120e4a3e7faba2e4c9af/easybuild/tools/modules.py#L494

I am working on fixing Lmod so that will only emit text from the execute command if the shell is "real". This means csh, bash and fish.

@rtmclay: did you get to fixing this in Lmod? If so, can you specify in which version this was fixed?
