sudo：jupyter：未找到命令＆OSError：[Errno 13] 权限被拒绝：'/usr/local/share/jupyter'

sudo：jupyter：未找到命令＆OSError：[Errno 13] 权限被拒绝：'/usr/local/share/jupyter'

如果我尝试检查是否jupyter在我的路径中或未被使用，我会得到一些回报。

which jupyter
/home/usr/.local/bin/jupyter

但是当我尝试安装并启用扩展时，出现错误：

sudo jupyter serverextension enable --py ipyparallel
sudo jupyter nbextension install --py ipyparallel
sudo jupyter nbextension enable --py ipyparallel

错误说sudo: jupyter: command not found

而且我需要 sudo 访问权限。因为没有 sudo 执行，无法完成工作：

jupyter serverextension enable --py ipyparallel
jupyter nbextension install --py ipyparallel 
jupyter nbextension enable --py ipyparallel 
Enabling: ipyparallel.nbextension

      ipyparallel.nbextension  OK

在这种情况下(^)，错误提示如下：OSError: [Errno 13] Permission denied: '/usr/local/share/jupyter'

那么我该如何解决这个问题？

我export PATH="$HOME/.local/bin:$PATH"在最后一行添加了~/.bashrc

答案1

当您使用 时sudo，将启用不同的环境。因此，您的私有 bin 文件夹 ( /home/usr/.local/bin/jupyter) 不再位于搜索路径中，并且不再能找到该命令。

有效路径在 sudoers 文件中定义。在 Ubuntu 上，它显示为：

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

因此，请在 ( ) 中安装二进制文件，/usr/local/bin以便在通过命令运行时找到它sudo。按照惯例，这是针对手动安装的可执行文件的目录，即由管理员手动管理，而不是由发行版自动管理。

或者，将二进制文件保留在原处并使用命令-E的选项sudo。这样可以保留您当前的环境，包括路径。一些想法：1) 操作系统必须允许这样做（Ubuntu 允许这样做）；2) 如果可能的话，最好不要在自己的用户文件夹中执行需要 root 权限的操作；3) 绝对不要以这种方式运行图形程序，因为它可能会弄乱权限。
