I have tried creating it 2 different ways.
我试过用 2 种不同的方式创建它。
sayth@sayth-TravelMate-5740G:~/scripts$ python3 -m venv test4
Error: Command '['/home/sayth/scripts/test4/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
sayth@sayth-TravelMate-5740G:~/scripts$ source test4/bin/activate
bash: test4/bin/activate: No such file or directory
sayth@sayth-TravelMate-5740G:~/scripts$ ls test4/bin/
python python3
or
或者
sayth@sayth-TravelMate-5740G:~/scripts$ pyvenv-3.4 test5
Error: Command '['/home/sayth/scripts/test5/bin/python3.4', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
sayth@sayth-TravelMate-5740G:~/scripts$ ls test5/bin/
python python3 python3.4
How can I get it to fully create a venv?
我怎样才能让它完全创建一个venv？
If I do it as below with stil no success unsure what the issue is?

Looks like you are using Ubuntu 14.04. It was shipped with a brokenpyvenv. There is a simple work around to create venv using Python 3
看起来您正在使用Ubuntu 14.04. 它带有一个破损的pyvenv. 有一个简单的工作来创建 venv 使用Python 3
1. Create venv without pip
1. 不用pip创建venv
python3 -m venv --without-pip test4
or
或者
pyvenv-3.4 --without-pip test4
2. Get pip in your env
2. 在你的环境中获取 pip
source test4/bin/activate
curl https://bootstrap.pypa.io/get-pip.py | python
deactivate
source test4/bin/activate
or
或者
pyvenv-3.4 --without-pip myvenv
source ./myvenv/bin/activate
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-3.4.4.tar.gz
tar -vzxf setuptools-3.4.4.tar.gz
cd setuptools-3.4.4
python setup.py install
cd ..
wget https://pypi.python.org/packages/source/p/pip/pip-1.5.6.tar.gz
tar -vzxf pip-1.5.6.tar.gz
cd pip-1.5.6
python setup.py install
cd ..
deactivate
source ./myvenv/bin/activate

This worked for me:
这对我有用：
python3 -m venv --without-pip test4
Once I typed that in the terminal, the "test4" venv was created. And the 'activate' script was also created in the 'bin' directory.
一旦我在终端中输入，就创建了“test4”venv。并且在 'bin' 目录中也创建了 'activate' 脚本。
To anyone using python3, having trouble with this, just substitute the name of the directory you want to create for "test4" (or rename it later).
对于任何使用 python3 的人，遇到这个问题，只需将要创建的目录的名称替换为“test4”（或稍后重命名）。
That should do it.
应该这样做。

Anaconda involucred.

If you are usingAnacondaorMinicondathis solution may help:
如果您使用的是Anaconda或Miniconda，此解决方案可能会有所帮助：
Conda manages python itself as a package, so that conda update python is possible, in contrast to pip, which only manages Python packages. Conda is available in Anaconda and Miniconda (an easy-to-install download with just Python and conda).
Conda 将python 本身作为一个包来管理，这样conda 更新python 是可能的，而pip 只管理Python 包。Conda 在 Anaconda 和 Miniconda 中可用（只需 Python 和 conda 即可轻松安装下载）。
So, this command would help:
所以，这个命令会有所帮助：
conda update python
对我来说非常令人不安，但好吧，在终端窗口中将手放在键盘上：（单击此处，查看图片）
Thanks for your attention, have a nice day!
