and I found that this is fixed in distro 1.6.0,please update this requirement

Actually, there are 2 things here:

• Update distro 1.6.0 if not risk of breaking
• Fix OSInfo().is_cygwin if possible so it doesn't raise in this way for this platform.

#9462 is upgrading the distro version, this will be released in 1.40
