Failed to install python 3.6.10 but it worked for python 3.7.6

I got an issue with zlib when install 3.6.10 with this command: sudo-pythonz install 3.6.10 (also failed with 3.6.8, 3.6.9)

Traceback (most recent call last):
  File "/Users/thoong/.pythonz/build/CPython-3.6.10/Lib/runpy.py", line 193, in _run_module_as_main

But it worked with sudo-pythonz install 3.7.10

So I think zlib is not a issue, because I already config in .zshrc

# zlib
export LDFLAGS="${LDFLAGS} -L/usr/local/opt/zlib/lib"
export CPPFLAGS="${CPPFLAGS} -I/usr/local/opt/zlib/include"
export PKG_CONFIG_PATH="${PKG_CONFIG_PATH} /usr/local/opt/zlib/lib/pkgconfig"

It seemed that sudo-pythonz didn't preserve those env vars

It seems work now, here is my config I put in ~/.zshrc

# openssl
export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

# zlib
export LDFLAGS="${LDFLAGS} -L/usr/local/opt/zlib/lib"
export CPPFLAGS="${CPPFLAGS} -I/usr/local/opt/zlib/include"
export PKG_CONFIG_PATH="${PKG_CONFIG_PATH} /usr/local/opt/zlib/lib/pkgconfig"

export CPATH=`xcrun --show-sdk-path`/usr/include
