我试图在我的终端做一个gem update
,但得到一个错误:
Updating installed gems
Updating actionpack
Fetching: activesupport-5.0.0.gem (100%)
Successfully installed activesupport-5.0.0
Fetching: rack-2.0.1.gem (100%)
ERROR: While executing gem ... (Errno::EACCES)
Permission denied @ rb_sysopen - /Users/MacBook/.rvm/gems/ruby-2.3.1@global/wrappers/rackup
谁能帮助我为什么得到这个?
如果有人想知道,我想我只需要给予许可,为了做到这一点,只需在前面添加sudo
命令,即:
$ sudo gem update
