Answer 1

with open(dst, 'wb') as fdst

Seperti dalam ayat di atas, pip perlu menulis beberapa fail semasa memasang perpustakaan, jadi 写入权限 diperlukan Jika mengikut kaedah di atas, menambah pip sebelum arahan sudo masih tidak berfungsi , anda boleh mempertimbangkan untuk menambah /usr/lib/python2.7/Tukar kebenaran direktori kepada 666 atau 777:

chmod 777 /usr/lib/python2.7

Answer 2

Kebenaran ditolak

Isu kebenaran, tambah sudo
