所有预安装的Python包都自动包含在新的Virtualenv中

自从在macOS Catalina中从BASH迁移到ZSH并试图删除Python2后，我就遇到了这个问题，但没有成功，因此我放弃删除Python2。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：

以下是我的配置：

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

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 Please upgrade your Python as Python 2.7 is no longer maintained.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.

每次在您创建的任何虚拟环境中都会包含Pip。

---

pip需要添加新的库，就像您在安装Django的freeze时使用的pip一样。

您可能希望在虚拟环境运行时查看

哪个python

。已激活。我最近遇到了一个类似的问题，Python在激活的虚拟环境中。只需指向系统python即可。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？很抱歉向您指出，但尚未找到解决方案。

问题是

pip：别名为/usr/local/bin/pip

---

使用

未关联的pip清理别名后

问题解决了

有什么问题？是否要为python3创建virtualenv？如果是这样，您需要在创建时将其作为参数传递给virtualenv。例如，

virtualenv测试--python$（哪个python3）

。

pip

的命令在你的venv中仍将显示为

pip

，但它将用于python3。我编辑了这个问题，我的意思是看底部的pip冻结，所有的包都已经存在，即使我刚刚创建了venv。我编辑了这个问题，我的意思是看底部的pip冻结，所有的包都已经存在，即使我只是创建了venv。结果如下：
