Ruby: LoadError - library not found for class Digest::SHA1 -- digest/sha1

Question

When running pod install it runs into a problem when installing yoga. Seems to be a problem with my ruby environment?

$ pod install

Answer 1

For me the me problem started after an unsolicited system update.

Uninstalling ruby and installing it again solved the issue:

rbenv uninstall 2.5.1
rbenv install 2.5.1

Answer 2

there is issue with ruby version. Install latest

brew install ruby

below command will overwrite the previous version

brew link --overwrite ruby

close this terminal and open new terminal.check your version

ruby -v

check issue resolve or not

ruby -r digest/sha1 -e 'p Digest::SHA1'

expected output : Digest::SHA1

Answer 3

Since this worked me, I am posting it as a comment.

After running

rbenv uninstall 2.5.1

if the below command is giving you an error (with ruby not installing)

rbenv install 2.5.1

maybe run this (for mac path)

RUBY_CONFIGURE_OPTS=--with-openssl-dir=/usr/local/Cellar/openssl/1.0.2q rbenv install 2.3.5
