root@app1:~# gem -v
1.8.10
当我使用rvm时,我得到1.8.10。但是当我使用sudo时,我得到了:
root@app1:~# sudo gem -v
1.3.7
现在我在另一个用户上安装gem而不是root
test@app1:~$ gem install RedCloth
Fetching: RedCloth-4.2.8.gem (100%)
ERROR: While executing gem ... (Errno::EACCES)
Permission denied - /usr/local/rvm/gems/ree-1.8.7-2011.03/cache/RedCloth-4.2.8.gem
哪里出错了?
当我不使用sudo

这里要注意三件事:
sudo
在用户切换期间清除其中的大多数作为安全措施,以防止攻击者将危险变量(如LD_PRELOAD
)注入提升的执行上下文。如果您想使用sudo并希望在新shell中保留RVM环境,请改用rvmsudo
。rvm
的组,并确保其所有成员都可以写入需要安装rubies,创建gemsets和安装gem的RVm目录。确保您的用户在该组中。或者您可以使用rvmsudo
