perl – 为什么plenv install-cpanm安装到错误的位置？

plenv install-cpanm

!   - Configure local::lib in your existing shell to set PERL_MM_OPT etc.
!   - Install local::lib by running the following commands

!         cpanm --local-lib=~/perl5 local::lib && eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)

App::cpanminus is up to date. (1.7042)

$plenv which cpanm
plenv: cpanm: command not found

$find /Users/olaf | grep bin/cpanm
/Users/olaf/.cpanm/work/1482416411.97013/App-cpanminus-1.7042/bin/cpanm
/Users/olaf/.cpanm/work/1482416863.23085/App-cpanminus-1.7042/bin/cpanm
/Users/olaf/perl5/bin/cpanm

$find /Users/olaf/.plenv | grep cpanm
/Users/olaf/.plenv/libexec/plenv-install-cpanm
/Users/olaf/.plenv/plenv.d/rehash/rehash_cpanm.bash

我希望cpanm安装在?/ .plenv里面的某个地方,但那只是没有发生.我猜我的点文件/ shell设置/ $ENV搞砸了？

这就是我的$ENV的样子：

env | grep PLENV
PLENV_SHELL=bash

另外,我的PATH的开头是：

PATH = /用户/奥拉夫/ .plenv /垫片：/Users/olaf/.plenv/bin
