[ykhandelwal913]

In jenkins job , i am setting up COCOAPODS_VERSION=1.4.0
but it is not picking up the correct version and instead using the old.

[ykhandelwal913]

also it shows error

podenv versions

• 1.0.0 (set by /Users/XXXX/.podenv/version)
  1.4.0

pod --version
/Users/XXXX/.podenv/libexec/../libexec/podenv-exec: line 31: /Users/XXXX/.podenv/versions//bin/pod: No such file or directory

How to change the version runtime? i tried export COCOAPODS_VERSION=1.4.0
then it shows

podenv versions
1.0.0
1.4.0

podenv versions
1.0.0
1.4.0

podenv version
(set by COCOAPODS_VERSION environment variable)

pod --version
/Users/ctobuilduser/.podenv/libexec/../libexec/podenv-exec: line 31: /Users/ctobuilduser/.podenv/versions//bin/pod: No such file or directory
