No module named virtualenvwrapper 虚拟环境报错

No module named virtualenvwrapper 虚拟环境报错

1. 安装虚拟环境命令

sudo pip install virtualenv
sudo pip install virtualenvwrapper

# 1、创建目录用来存放虚拟环境
mkdir $HOME/.virtualenvs    # $HOME代表家目录，用于保存虚拟环境产生的目录

# 2、打开~/.bashrc文件，并添加如下：
export WORKON_HOME=$HOME/.virtualenvs  # 导入虚拟环境保存的目录
source /usr/local/bin/virtualenvwrapper.sh  # 添加命令的路径

# 3、运行
source ~/.bashrc  # 让命令生效

接下来如果出现下列报错的话，是因为在~/.bashrc这个文件中没有设置python解释器的路径

/usr/bin/python: No module named virtualenvwrapper
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=/usr/bin/python and that PATH is
set properly.

需要插入如下代码

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv

然后再运行命令

source ~/.bashrc

如果出现下面的输出

virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/initialize
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/premkvirtualenv
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/postmkvirtualenv
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/prermvirtualenv
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/postrmvirtualenv
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/predeactivate
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/postdeactivate
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/preactivate
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/postactivate
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/get_env_details
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/premkproject
virtualenvwrapper.user_scripts creating /home/ubuntu/.virtualenvs/postmkproject

表示虚拟环境的命令导入成功了，可以正常使用
