所有预装 Python 包自动包含在新的 Virtualenv 中

Question

自从在 macOS Catalina 中从 BASH 移动到 ZSH 并尝试删除 python 2 后，我遇到了这个问题，但没有成功，所以我放弃删除 python 2. 因此，每次我创建新的 Virtualenv 时，所有全局包都会自动包含在新的 Virtualenv 中：

这是我的配置：

dlintin@Linns-MBP belajar_django % python --version
Python 2.7.16
dlintin@Linns-MBP belajar_django % python3 --version
Python 3.7.6
dlintin@Linns-MBP belajar_django % which python        
/usr/bin/python
dlintin@Linns-MBP belajar_django % which python3
/usr/local/bin/python3
dlintin@Linns-MBP belajar_django % pip -V
pip 20.0.2 from /Library/Python/2.7/site-packages/pip (python 2.7)
dlintin@Linns-MBP belajar_django % pip3 -V
pip 19.0.3 from /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)
dlintin@Linns-MBP belajar_django % which pip   
pip: aliased to /usr/local/bin/pip
dlintin@Linns-MBP belajar_django % which pip3
/usr/bin/pip3

dlintin@Linns-MBP belajar_django % which virtualenv
/usr/local/bin/virtualenv

dlintin@Linns-MBP belajar_django % virtualenv test

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7.

Answer 1

每次您创建的任何虚拟环境中都会包含 Pip。需要 pip 来添加新库，就像您使用 pip 来安装 Django 的冻结一样。

Answer 2

你可能想看看 which python 你的虚拟环境。被激活。我最近遇到了类似的问题，激活的虚拟环境中的 Python 。只会指向系统 python。我正在使用 Win7x64 并在符号链接目录中安装了 Python。你也在使用符号链接吗？抱歉让您失望了，目前还没有找到解决办法。

Answer 3

问题是pip: aliased to /usr/local/bin/pip 使用 unaliased pip 清理别名后问题解决了！
