and using the production group of your Gemfile.
This may be intentional, if you expected rake tasks to be run
cancel the build (CTRL+C) and fix the error then commit the fix:
rake aborted!
我没有任何我想自动运行的rake任务.我应该忽略这个警告吗？

#include <stdio.h>
/* count lines in input */
main()
{
int c, nl;
nl = 0;
while ((c = getchar()) != EOF)
if (c == '\n')
++nl;
printf("%d\n", nl);
}
跑
./a.out
按ctrl+d发送EOF
0D
它应该只是0.为什么它附加D？这是什么意思？
