我是否应该担心（在运行 ~/.local/bin/virtualenvwrapper.sh 之后）“找不到命令，但可以安装：...””（Ubuntu 桌面）？答案

【问题标题】：Should I worry about (after running ~/.local/bin/virtualenvwrapper.sh) "Command '' not found, but can be installed with:..."" (Ubuntu Desktop)?我是否应该担心（在运行 ~/.local/bin/virtualenvwrapper.sh 之后）“找不到命令，但可以安装：...””（Ubuntu 桌面）？

【问题描述】：

我在学习本教程时遇到了问题：

https://docs.python-guide.org/dev/virtualenvs/ 它告诉我运行“source /usr/local/bin/virtualenvwrapper.sh” 但由于它不存在，updatedb 和 locate 报告它位于： "~/.local/bin/virtualenvwrapper.sh"

所以遇到这个问题似乎阻止了我前进：

charles@lamborghini:~$ source ~/.local/bin/virtualenvwrapper.sh

Command '' not found, but can be installed with:

sudo apt install bpfcc-tools   # version 0.8.0-4, or
sudo apt install mailutils-mh  # version 1:3.5-2build1
sudo apt install mmh           # version 0.4-2
sudo apt install nmh           # version 1.7.1-4

virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON= and that PATH is
set properly.
charles@lamborghini:~$ echo $VIRTUALENVWRAPPER_PYTHON

charles@lamborghini:~$

我应该担心吗？ mkvirtualenv 工作正常。

这是正确的答案。尽管您也是操作者，但您应该接受它。
