建议使用pip install module-name -t /path/to/project-dir,但是我不知道该t标志的用途。有人能帮我吗?
从手册:
Run Code Online (Sandbox Code Playgroud)-t, --target <dir> Install packages into <dir>. By default this will not replace existing files/folders in <dir>. Use --upgrade to replace existing packages in <dir> with new versions.
