Under Windows Linux Subsystem and Ubuntu 18.04, this was caused by my not having upgraded recently.

I ran:

<pre><code>sudo apt update

Then <code>sudo apt install python3-venv</code> worked.

Note that I had also tried the <a href="https://stackoverflow.com/a/39539571/309334">UTF-8 solution</a> beforehand (I made it part of my <code>.bashrc</code>), so that could have been a contributing factor.

Resolved similar problems on Ubuntu18 when came upon <a href="https://stackoverflow.com/a/53071893/3398492">this answer</a>. It is similar to the one that worked for @Niko Rikken, except it doesn't really need any new PPA's and &quot;python3.8-distutils&quot; package. I was installing new python3.8 environment with venv and I already had &quot;python3-venv&quot; installed and up to date, so my solution was to install only &quot;python3.8-venv&quot;:
<pre><code>% sudo apt-get install python3.8-venv

And that got this lines working:
<pre><code>% python3.8 -m venv ~/envs/new_env

In case this helps anyone down the line, I was getting the same error on Ubuntu 18.04. Setting the locales didn't work and trying to install <code>python3-venv</code> gave the error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python3-venv : Depends: python3.6-venv (&gt;= 3.6.5-2~) but it is not going to be installed
 Depends: python3 (= 3.6.5-3) but 3.6.7-1~18.04 is to be installed
E: Unable to correct problems, you have held broken packages.

And it looks like the apt repository had two versions of python:

<pre><code>$ apt list python3 -a
python3/bionic-updates,now 3.6.7-1~18.04 amd64 [installed]
python3/bionic 3.6.5-3 amd64
</code></pre>

I tried to install <code>Python3.6.5-3</code> but apt wanted to uninstall every dependency. I was able to solve the problem by installing Python3.7 and creating the venv with that:

<pre><code>$ sudo apt-get install python3.7 python3.7-venv
$ python3.7 -m venv my_venv
</code></pre>

I encountered this problem on Ubuntu 18.04 for the recent release of Python-3.8. My solution was to add the <a href="https://launchpad.net/%7Edeadsnakes/+archive/ubuntu/ppa" rel="noreferrer">Deadsnakes PPA</a> which supplies the required <code>python3.8-distutils</code> package. The <code>python3.8-venv</code> package is already in the repository. Thanks to <a href="https://dev.to/mortoray/how-to-install-python-3-8-on-ubuntu-1bp4" rel="noreferrer">this blogpost</a>:
<pre class="lang-sh prettyprint-override"><code>sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.8
sudo apt install python3.8-distutils
sudo apt install python3.8-venv
</code></pre>
Note: This is only a temporary solution. In the near future the required <code>python3.8-distutils</code> package will probably be available in the default Ubuntu repository.
Edit:
For Ubuntu 20.04 LTS the <a href="https://packages.ubuntu.com/focal/python3-distutils" rel="noreferrer">python3-distutils</a> package is based on Python 3.8. As of yet there is no Python 3.8 package distutils package available for Ubuntu 18.04 LTS.
As mentioned in other comments on this thread, <code>distutils</code> might not be required. It was for my use-case, but please consider that solution before adding additional PPA's.

Python updated or Default python changed and venv already installed
the venv installed on your system is installed by your previous python version(let say python3.6). that's why venv is not working with current python version(lets say 3.8).
so first check your default python or python3 version,( suppose ur current version is python3.8).
reinstall virtual environment by mentioning current python version(3.8) as follow
<pre><code>sudo apt-get install python3.xx-venv &gt;&gt; replace xx with your current/default python version
</code></pre>

I just ran across this issue on several Debian/Ubuntu systems. Same error as above.
<h2>Findings</h2>
I tried to create a venv manually with:
<pre><code>python -m venv venvdir
</code></pre>
This failed in the same way as others have mentioned. But it did create the shell of the venv. So I tried running ensurepip:
<pre><code>venvdir/bin/python -m ensurepip

</code></pre>
This seemed odd. A quick look into <code>/usr/share/python-wheels/</code> revealed - indeed - multiple versions of the same wheel as the error suggests. I have no clue why ensurepip is also ensuring that it only finds one wheel file, go figure.
<h2>Solution</h2>
A check of <code>dpkg -S /usr/share/python-wheels</code> indicated that the <code>python-pip-whl</code> package is the source of those files. This appears to be true for both Ubuntu and Debian.
So, I did:
<pre><code>cd /usr/share
sudo mv python-wheels python-wheels.old
sudo apt reinstall python-pip-whl
</code></pre>
And it worked - no more errors. There are no longer duplicates in <code>/usr/share/python-wheels</code>
Absolutely no clue how there were duplicates or why ensurepip is so sensitive to duplicates there... Probably a package upgrade gone wrong somewhere.

Here is my answer for Ubuntu 14.04. I was able to make venv and pip work with various Python versions. Details:
<ul>
<li>3.4: Ubuntu 14.04 has Python 3.4 (as package python3.4 etc.). It works:
<pre class="lang-sh prettyprint-override"><code>$ sudo apt-get install python3.4 python3.4-dev python3.4-venv gcc libc6-dev
$ mkdir /tmp/try3.4
$ python3.4 -m venv /tmp/try3.4
$ . /tmp/try/bin/activate
(try3.4) $ pip install print-hello-world
...
(try3.4) $ print-hello-world
Hello World!
</code></pre>
If <code>python3.4-venv</code> is removed from the <code>apt-get install</code> command above, then <code>python3.4 -m venv</code> displays the same error message as in the question. However, the error message mentions <code>apt-get install python3-venv</code> to solve it, but that doesn't work, there is no such package. (The correct package name is <code>python3.4-venv</code>.)
Please note that Python 3.4 is fairly old, and some Python packages available in PyPI (via pip) don't work with it.
</li>
<li>3.5: It can be installed from the deadsnakes repository. It works:
<pre class="lang-sh prettyprint-override"><code>$ sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt-get update
$ sudo apt-get install python3.5 python3.5-dev python3.5-venv gcc libc6-dev
$ mkdir /tmp/try3.5
$ python3.5 -m venv /tmp/try
$ . /tmp/try/bin/activate
(try3.5) $ pip install print-hello-world
...
(try3.5) $ print-hello-world
Hello World!
</code></pre>
</li>
<li>3.6: Ditto, it can be installed from the deadsnakes repository. It works:
<pre class="lang-sh prettyprint-override"><code>$ sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt-get update
$ sudo apt-get install python3.6 python3.6-dev python3.6-venv gcc libc6-dev
$ mkdir /tmp/try3.6
$ python3.6 -m venv /tmp/try3.6
$ . /tmp/try3.6/bin/activate
(try3.6) $ pip install print-hello-world
...
(try3.6) $ print-hello-world
Hello World!
</code></pre>
</li>
<li>3.7: It doesn't work, because <code>pip install</code> fails with <code>import _ssl</code>, and python3.7 in the deadsnakes repo doesn't have that module, because Ubuntu 14.04 ships with on old version of OpenSSL which Python 3.7 doesn't support. See more details in <a href="https://github.com/deadsnakes/issues/issues/63" rel="nofollow noreferrer">this bug</a>.
</li>
<li>3.8--: No Ubuntu 14.04 package for these Python versions in the Ubuntu or deadsnakes repositories.
</li>
</ul>

blocks|key|1575098|text|最近遇到了同样的问题。上面提到的解决方案对我来说都不起作用。我最终通过安装pip3使其正常工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1575099|apt-get+install+python3-pip

Ran into the same issue recently. None of the solutions mentioned above worked for me. I eventually get it to working by installing pip3.
<pre class="lang-sh prettyprint-override"><code>apt-get install python3-pip

# then run
python3.8 -m venv env
</code></pre>

blocks|key|5436106|text|如果您在尝试运行python+-m+build构建python包时遇到此问题，这意味着您的setup.cfg或setup.py文件中可能存在语法问题，导致创建安装依赖项所需的临时venv时出错。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5436107|使用pip+wheels+.可以减少错误消息的误导性。|5436108|entityMap^0|8|F|19|9|1J|8|0|2|C|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|I|$]]

If you came across this issue while trying to run <code>python -m build</code> to build a python package, this means there probabaly is a syntax issue in your <code>setup.cfg</code> or <code>setup.py</code> file that causes an error creating the temporary venv required for installing dependencies.
Using <code>pip wheels .</code> will give you a less misleading error message.

For Linux, it is not installed by default you have to install venv

<li>Run: &lt;path&gt;/bin/python3 get-pip.py</li>
</ol>
I did 'source &lt;path&gt;/bin/activate' and I got a working environment.

When I try to create a virtual env by using
<pre><code>pyvenv .venv

or
<pre><code>python3 -m venv .venv

There is an error:
<pre><code>The virtual environment was not created successfully because ensurepip is not

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

Failing command: ['/home/user/.venv/bin/python3.5', '-Im', 'ensurepip', '--upgrade', '--default-pip']

I tried running both
<pre><code>sudo apt-get install python3-venv

and
<pre><code>sudo apt-get install python3.5-venv
