How do I install SQLite 3.6 on Windows 7?
I extracted sqlite3.exe, sqlite3.dll, and sqlite3.def to C:\Windows\System32 but when I try to run a Ruby program that requires the use of sqlite3, I get this error:
The program can't start because sqlite3.dll is missing from your computer. Try reinstalling the program to fix this problem.
回答1:
I would try adding the path to SQLite in PATH.
Supplemental: SQLite 3 is not "installed". It's a DLL, usually unregistered. Most software using SQLite 3 will rely on a local copy or one referenced in an environment variable.

Just tried this on Windows 7 Ultimate 64 bit. Didn't like it when I put it in the ruby/bin folder. Didn't like the \Winodws\System32 either... put it in the \Windows\system and it ran... go figure... anyway fyi for 64bit.

Windows 7 64 bit here as well, putting them in \Windows\system did it for me.
Actually I was installing this for HDBC and Haskell following the instructions at http://wiki.github.com/jgoerzen/hdbc/frequentlyaskedquestions
The only difference for Windows 7 64 bit is in the below instruction -
"Put “sqlite3.dll” from sqlitedll-3*.zip into ghc --print-libdir and into %windir%\system32."
The file should be copied into the \Windows\system instead of the %windir%\system32 folder.

I had this problem when trying to run Rake (bundle exec rake db:migrate).
I tried setting the PATH, and copying the SqlLite binaries to C:\Windows\System32 but to no avail.
Finally solved it by copying the binaries to my Ruby bin directory (C:\Ruby192\bin), based on advice from this post: http://www.ruby-forum.com/topic/216270#977959.
