当我尝试运行虚拟环境时没有激活

Question

1)我使用pip安装了virtualenv.
2)我运行命令virtualenv venv
3)然后我跑了,source venv/bin/activate但它说没有这样的文件或目录.

当我cd进入venv/bin我发现3件事 - python,python 2.7和python 3.5.有谁知道这个问题？

Answer 1

我曾经也有过一样的问题.而我所做的只是virtualenv env 再次运行命令 .然后在目录env/bin下生成更多文件,包括激活文件.这太奇怪了.也许你可以尝试更多.

Answer 2

根据Python doc，安装步骤是

$ python3 -m pip install --user virtualenv

$ python3 -m venv env

最后一条命令给出警告消息，

The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt-get install python3-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

现在，activate可用。

我解决了运行中的类似问题python3.7 -m venv venv，您可以更改安装在您环境中的python版本。
