[Ruby] rvm pkg install zlib → [ERROR] There is no checksum for xxx

Wed, October 3, 2012 - 1 min read

RVM で zlib インストールしようとしたら、チェックサム無いってエラーでインストールできないときの対処方法をメモ。

# rvm pkg install zlib
Fetching zlib-1.2.7.tar.gz to /usr/local/rvm/archives
There is no checksum for 'http://prdownloads.sourceforge.net/libpng/zlib-1.2.7.tar.gz' or 'zlib-1.2.7.tar.gz', it's not possible to validate it.
If you wish to continue with unverified download add '--verify-downloads 1' after the command.

Please note that it's required to reinstall all installed rubies:

    rvm reinstall all --force
    rvm all-gemsets do rvm gemset pristine


rvm --verify-downloads 1 pkg install zlib 
rvm get head
