python - bash_profile 配置困惑

Question

我正在尝试使用此链接中的第 5 步安装 Python 虚拟环境 Install OpenCV 3 on macOS with Homebrew (the easy way)

我在正确配置这个文件时遇到了问题

$ nano ~/.bash_profile

只编辑 bash_profile like show

# Virtualenv/VirtualenvWrapper
source /usr/local/bin/virtualenvwrapper.sh

不允许我进入下一步

我收到这个警告 mkvirtualenv: command not found

因此使用此 techstricks.com/mkvirtualenv-command-not-found-virtualenvwrapper/

的帮助改变了它

找到关于如何使用 virtualenwrapper 的链接 virtualenvwrapper.readthedocs.io/en/latest/install.html#python-interpreter-virtualenv-and-path

我的 bash_profile 包含

    #Homebrew
export PATH=/usr/local/bin:$PATH

export WORKON_HOME=$HOME/.virtualenvs

# Virtualenv/VirtualenvWrapper
source /usr/local/bin/virtualenvwrapper.sh
export PROJECT_HOME=$HOME/Devel
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages'

当我尝试 $ source ~/.bash_profile

我明白了

-bash: /usr/local/bin/python: No such file or directory
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/local/bin/python and that PATH is
set properly.

我该如何解决这个问题？？？？？？

Answer 1

我终于让它工作了。

我分别安装了 Virtualenv 和 Wrapper

pip install virtualenv

将来可能会帮助某人。
