Virtualenv：pip没有在正确的目录中安装Virtualenv

Question

Whenever I try running virtualenv, it returns command not found.

Per recommendations in other posts, I have tried installing virtualenv with both $ pip install virtualenv and $ sudo pip install virtualenv . I have uninstalled and tried again multiple times.

I think the issue is that I am using OSX, and pip is installing virtualenv in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages . As I understand, it should be installed in /usr/local/bin/ .

How can I install virtualenv there?

Answer 1

如果要在/ usr / local / bin /下安装它，可以在pip调用中添加--target=参数：

sudo pip install --target=/usr/local/bin virtualenv

Answer 2

Try adding /usr/local/share/python in /etc/launchd.conf and ~/.bashrc . This might resolve the issue you are facing.

Answer 3

In my case, on Ubuntu 16.04 (using Python 2.7)

case user shell:

$ (VirtualEnvironment) sudo pip install <package>  

that installs in systemwide libs

case root shell (sudo su -):

# (VirtualEnvironment) pip install <package>

installs in the VIRTUALENV_HOME/lib/python2.7/site-packages/

I'm installing for different applications under /var/www/ (each one in a different subdir)
