error when build xspress, line 357 in build_xspress3.py

[l123173]

hi,
I met a question during install the module, centos 7, x64.
after type: python build_xspress3.py all, got:
"build_xspress3.py line 357 "
out.append(f'{key}={subs[key]}')"

And i used the py last year, it was ok.
Now i do not know why it happened.

@l123173 Sorry for the trouble. I bet that is a Python2 vs. Python3 problem. Does it work to replace
(at

xspress3/build_xspress3.py

Line 357 in 2112012

out.append(f'{key}={subs[key]}')

)

                out.append(f'{key}={subs[key]}')

with

                out.append('%s=%s' % (key, subs[key]))

It looks like there are a few more places where Python3-only f-strings crept in, but those may not impact your build...

@l123173 I updated the build script so that it should now work with Python2

Hi Newvile,
Yes you are right, it was the Python2 vs. Python3 problem.
Now, it works well.

We did not know that we are using Python2 in 2023.

Than you so much

Hi Newvile,
Sorry, a little more question.

I got some error. And i think the error " Error#MCAs: create StdArray for Visualization: " was key.
But i did not change the db file.  i check for a long time and could not find how to slove it.

the error of st.cmd:

@l123173 Hm, not sure, I'll see if I can reproduce that....

[newville]

@l123173 Ah, I can see what you are getting. I believe that it was recently fixed. I'll push a release of 3.2.8, and update the build script to use the latest version....
