Troubleshooting

Traffic Control (tc)

If tc or tc --help outputs something like this:

(thermo-calc) ppak@MAIL-10:/mnt/am/ppak/GitHub/thermo-calc$ tc
Usage:  tc [ OPTIONS ] OBJECT { COMMAND | help }
        tc [-force] -batch filename
where  OBJECT := { qdisc | class | filter | chain |
                    action | monitor | exec }
       OPTIONS := { -V[ersion] | -s[tatistics] | -d[etails] | -r[aw] |
                    -o[neline] | -j[son] | -p[retty] | -c[olor]
                    -b[atch] [filename] | -n[etns] name | -N[umeric] |
                     -nm | -nam[es] | { -cf | -conf } path
                     -br[ief] }

its calling Traffic Control and use tcalc instead of tc

If you get something like this:

(thermo-calc) ppak@MAIL-10:/mnt/am/ppak/GitHub/thermo-calc$ uv add ~/Thermo-Calc/2025b/SDK/TC-Python/TC_Python-2025.2-30-py3-none-any.whl

warning: Failed to hardlink files; falling back to full copy. This may lead to degraded performance.
         If the cache and target directories are on different filesystems, hardlinking may not be supported.
         If this is intentional, set `export UV_LINK_MODE=copy` or use `--link-mode=copy` to suppress this warning.

  Caused by: Wheel version does not match filename: 2025.2.30 != 2025.2

you need to change the - to a . by renaming TC_Python-2025.2-30-py3-none-any.whl to TC_Python-2025.2.30-py3-none-any.whl.

JAVA_HOME not found

You'll need to set this if you installed java via brew

echo export "JAVA_HOME=\$(/opt/homebrew/opt/openjdk)" >> ~/.zshrc
