我使用RPI3B并尝试安装Virtualenvwrapper和Virtualenvs。在我添加
之后export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
在〜/ .profile中。然后source ~ ~/.profile我用mkvirtualenv cv -p python2。之后，我得到这些消息：
created virtual environment CPython2.7.16.final.0-32 in 672ms

virtualenvwrapper.user_scripts creating /home/pi/.virtualenvs/cv/usr/local/bin/predeactivate
ERROR: Environment '/home/pi/.virtualenvs/cv' does not contain an activate script.
但是我不能使用workon cv。最后一条消息一次又一次地出现。我该如何解决？我也尝试重新安装它，但没有帮助。
当我在新的RPI4上使用mkvirtualenv时，我有相同的错误消息。我将这些行添加到我的.bashrc中，它为我解决了问题：
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh
export VIRTUALENVWRAPPER_ENV_BIN_DIR=bin # <== This line fixed it for me
