mkvirtualenv --no-站点包命令得到“未找到命令”错误

Question

我的virtualenv和virtualenvwrapper安装，而是试图建立一个应用程序时，我进入mkvirtualenv --no-site-packages我得到以下错误：

-bash: mkvirtualenv: command not found

我不知道如何解决这个问题。作为初学者，我会很感激任何帮助。

Answer 1

您需要启用virtualenvwrapper，如its docs中所述。

Shell Startup File

Add three lines to your shell startup file (.bashrc , .profile , etc.) to set the location where the virtual environments should live, the location of your development project directories, and the location of the script installed with this package:

export WORKON_HOME=$HOME/.virtualenvs 
export PROJECT_HOME=$HOME/Devel 
source /usr/local/bin/virtualenvwrapper.sh 

After editing it, reload the startup file (e.g., run source ~/.bashrc).

Answer 2

取决于你如何安装呢？这实际上可以改变一点点。如果你使用apt将它安装在Ubuntu上，那么virtualenvwrapper函数实际上会被放入一个bash完成文件（找出它很有趣！）。

export WORKON_HOME=$HOME/.virtualenvs 
export PROJECT_HOME=$HOME/Devel 
possible_scripts='/usr/local/bin/virtualenvwrapper.sh /etc/bash_completion.d/virtualenvwrapper' 
for script in $possible_scripts; do 
    [[ -f $script ]] && source $script 
done
