Question

我正在尝试设置普通的python3虚拟环境。

我创建了我的虚拟环境并将其激活

virtualenv . && source bin/activate

但是当我python3 --version和pip3 freeze时，我看到的不仅仅是默认的python3库。

以下是python3 --version输出

(socketdirectory) lawn-143-215-57-83:socketdirectory jaeminbaek$ python3 --version
Python 3.6.1 :: Anaconda 4.4.0 (x86_64)

这是pip3 freeze结果输出

zewn-143-215-57-83:socketdirectory mycomputer$ source bin/activate pip3 freeze
backports.weakref==1.0rc1

six==1.10.0
snowballstemmer==1.2.1
tensorflow==1.2.1
Theano==0.9.0
urllib3==1.22
Werkzeug==0.12.2

为什么要导入这么多的库？

更新我在使用virtualenv -p python3 venv

时收到此错误

Answer 1

您正在使用python 2.7

创建虚拟环境

pip freeze

当您触发哪个pip3时它不会显示新虚拟环境下的pip，它将显示包含许多库的全局pip3。

要执行pip3，您应该通过显式提供python3标志来创建虚拟环境

virtualenv -p python3 . && source bin/activate
pip3 freeze
pip freeze

这将为您提供正确的结果。交叉检查总是激活命令

which pip
which pip3

上面的命令将显示您正在使用的是哪个点。在您的情况下，使用了usr / bin / pip3

在`virtualenv .`
