Can't Find or create a new virtualenv
提问by Malik A. Rumi
I just got Python 3.5.2 and wanted to create a virtualenv.
我刚刚获得 Python 3.5.2 并想创建一个 virtualenv。
I have done this before. Right now, I have a virtualenv on a Python2.7 project that I can still open with source bin/activate.
我以前做过这个。现在，我在 Python2.7 项目上有一个 virtualenv，我仍然可以使用 source bin/activate 打开它。
But try as I might, from /home, or from /path/to/virtualenv, or /path/to/virtualenv-$, with or without sudo and python prepended on the command line, I only get one response: no such file or directory.
但是尽我所能，从 /home 或 /path/to/virtualenv 或 /path/to/virtualenv-$，无论是否在命令行中添加 sudo 和 python，我只得到一个响应：没有这样的文件或目录。
This was with the -p flag so it would use 3.5.2, because 2.7.12 is still my default. If it is broken, why does the virtualenv I created for 2.7 still activate?
这是带有 -p 标志的，因此它将使用 3.5.2，因为 2.7.12 仍然是我的默认值。如果坏了，为什么我为 2.7 创建的 virtualenv 仍然激活？
Then I tried pyvenv and venv (which I've never used before) from the 3.5.2 interpreter:
然后我从 3.5.2 解释器中尝试了 pyvenv 和 venv（我以前从未使用过）：
>>> pyvenv /home/malikarumi/Projects/aishah
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'pyvenv' is not defined
>>> venv /home/malikarumi/Projects/aishah
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'venv' is not defined
and from bash:
来自 bash：
malikarumi@Tetuoan2:~$ malikarumi@Tetuoan2:/usr/local/bin$ python3.5 pyvenv ~/Projects/aishah
bash: malikarumi@Tetuoan2:/usr/local/bin$: No such file or directory
malikarumi@Tetuoan2:~$ malikarumi@Tetuoan2:/usr/local/bin$ python3.5 venv ~/Projects/aishah
bash: malikarumi@Tetuoan2:/usr/local/bin$: No such file or directory
What am I doing wrong?
我究竟做错了什么？

Using virtualenv
使用 virtualenv
First of all you should verify that virtualenv is really installed for Python 3.5:
首先，您应该验证是否真的为 Python 3.5 安装了 virtualenv：
python3.5 -m pip list
python3.5 -m pip list
If it's not then install it either with the package manager of your distribution or by running python3.5 -m pip install virtualenv.
如果不是，则使用发行版的包管理器或运行python3.5 -m pip install virtualenv.
Then you can run python3.5 -m virtualenv <newvenv>and it should create a new virtualenv using Python 3.5 for you.
然后你可以运行python3.5 -m virtualenv <newvenv>，它应该使用 Python 3.5 为你创建一个新的 virtualenv。
Using venv that is already part of the standard library in Python 3.5
使用 venv 已经是 Python 3.5 标准库的一部分
Simply running python3.5 -m venv <newvenv>should do the job.
只需跑步就python3.5 -m venv <newvenv>可以完成这项工作。
