Tidak ada entri manual untuk pria

Saya bekerja dalam gambar Docker Centos 6.6 . Saya pikir saya menginstal semuanya untuk mendapatkan akses ke halaman manual, tetapi ternyata tidak ...

$ yum install -y man man-pages man-pages-overrides
[...]
Complete!
$ which man
/usr/bin/man
$ man man
No manual entry for man

Apa yang saya lewatkan?

Mengenai pertanyaan dalam komentar (terima kasih atas bantuan Anda semuanya):

$ echo $MANPATH
# empty
$ man 1 man
No entry for man in section 1 of the manual
$ man 7 man
No entry for man in section 7 of the manual

Lihat komentar re: menghapus tsflags=nodocsdari /etc/yum.conf, meletakkan di sana sebagai konsekuensi dari kebijakan pembuatan image docker dasar:

Saya baru saja menguji ini pada wadah CentOS 6.7 dan itu berhasil.

Jika echo $MANPATHkosong, Anda perlu mengatur jalur.

echo "MANPATH=/usr/share/man" >> ~/.bashrc

Login lagi.
