上面是我的dockerfile。
我只是想设置乘客nginx的模块...
但我在最后RUN指令Dockerfile遇到错误
RUN gem install passenger -v 4.0.55 \
&& rvmsudo passenger-install-nginx-module \
--auto --prefix=/usr/local/nginx --auto-download --languages ruby
首先，安装乘客， 其次，尝试安装nginx的模块通过rvmsudo passenger-install-nginx-module命令。
但码头工人响应此错误
错误：
Unable to autodetect the currently active RVM gem set name. This could happen if you ran this program using 'sudo' instead of 'rvmsudo'. When using RVM, you're always supposed to use 'rvmsudo' instead of 'sudo!'.
Please try rerunning this program using 'rvmsudo'. If that doesn't help, please contact this program's author for support.
虽然我只是试图指挥rvmsudo ...
我应该怎么办？
