安裝Raspberry OpenCV時出錯

Question

我正在嘗試使用python 3.5在樹莓派3b +上安裝opencv，但是由於這些文件我什至都沒有編輯，所以我一直遇到相同的錯誤。

 pi@raspberrypi:~ $ mkvirtualenv cv Using base prefix '/usr' Traceback (most recent call last): File "/usr/local/bin/virtualenv", line 11, in <module> sys.exit(main()) File "/usr/local/lib/python3.5/dist-packages/virtualenv.py", line 712, in main symlink=options.symlink) File "/usr/local/lib/python3.5/dist-packages/virtualenv.py", line 927, in create_environment site_packages=site_packages, clear=clear, symlink=symlink)) File "/usr/local/lib/python3.5/dist-packages/virtualenv.py", line 1112, in install_python mkdir(lib_dir) File "/usr/local/lib/python3.5/dist-packages/virtualenv.py", line 324, in mkdir os.makedirs(path) File "/usr/lib/python3.5/os.py", line 231, in makedirs makedirs(head, mode, exist_ok) File "/usr/lib/python3.5/os.py", line 231, in makedirs makedirs(head, mode, exist_ok) File "/usr/lib/python3.5/os.py", line 241, in makedirs mkdir(name, mode) PermissionError: [Errno 13] Permission denied: '/cv'

您無權在/ （根）目錄中創建目錄。 你可以

• 使用sudo mkvirtualenv cv ，或
• export WORKON_HOME=~/.virtualenvs然后mkvirtualenv cv
