嗨,我正在尝试从EC2服务器运行我的python代码。连接和所有都已经完成,这样就可以正常工作。然而,当我尝试运行代码时,它给了我一个错误,ImportError: No module named 'matplotlib'试图使用pip install matplotlib安装matplotlib,但是我得到了一个错误ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packa
我被pip的用法弄糊涂了。Pip是随Python一起安装的,这很棒,但当新版本发布时,我会收到以下警告:
WARNING: You are using pip version 21.1.1; however, version 21.1.3 is available.
You should consider upgrading via the '/usr/local/opt/python@3.8/bin/python3.8 -m pip install --upgrade pip' command.
我按照他们给出的命令进行安装。但随后它卸载了我现有的pip,并且无法安装新版本。
