感谢老师回复,抱歉，新手小白，一直想学好电脑。昨天看了老师回复，自己又看了别的同学的答复，又试了下，最后找不到 jupyterlab, 不知哪里出了问题，烦请老师指导；
usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin Richards-Air:pilot-student Richardz$ pip3 install jupyterlab WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
