Another possible solution has been suggested in a <a href="https://askubuntu.com/questions/1037666/youtube-dl-python-not-found-18-04/1037669#comment2100898_1149489">comment by Kulfy</a>, it deserves more visibility.
Starting from Ubuntu 20.04 (where the default version of python is <code>python3</code>) you can install the package <code>python-is-python3</code>:
<pre><code>sudo apt install python-is-python3
</code></pre>
What the package does is to interpret automatically the shebang <code>#!/usr/bin/env python</code> as a <code>python3</code> shebang. In this way you can call <code>youtube-dl</code> without prepending any command and/or without creating a specific alias in <code>~/.bashrc</code> file.
There is also an equivalent package for deprecated <code>python2</code>, called <code>python-is-python2</code>.

The head of the youtube-dl script has <code>#!/usr/bin/env python</code>, meaning that it uses the "python" command.

Per <a href="https://www.python.org/dev/peps/pep-0394/" rel="nofollow noreferrer">https://www.python.org/dev/peps/pep-0394/</a>
Distributions can choose include the python command linked to python2 or python3, not include the command at all, or allow the user/admin to configure it.

In debian-based installs, there are 3 main python packages:

<ul>
<li>python (<code>sudo apt install python</code>)</li>
<li>python2 (<code>sudo apt install python2</code>)</li>
<li>python3 (<code>sudo apt install python3</code>)</li>
</ul>

The "python" package installs python version 2 and includes the "python" command (symlink /usr/bin/python -> /usr/bin/python2).

The "python2" and "python3" packages do not provide the "python" command.
This means that calling "python" from the CLI or a script will result in a "command not found" error.

If you're using these, you have to either:

<ul>
<li>call the script using whichever version you like (<code>python2 /usr/local/bin/youtube-dl</code> or <code>python3 /usr/local/bin/youtube-dl</code>) [Personally, I have <code>alias youtube-dl='python3 /usr/local/bin/youtube-dl'</code> in my .bash_aliases]</li>
<li>edit the youtube-dl script to use python2 or python3 (<code>sudo sed -i '1s/python/python2/' /usr/local/bin/youtube-dl</code>) or (<code>sudo sed -i '1s/python/python3/' /usr/local/bin/youtube-dl</code>)</li>
</ul>

In the above, I prefer using the aliasing option since you leave the file alone and don't have to edit it every time the file gets updated

It's also possible to fix it by creating a symlink for /usr/bin/python, but that is not adviseable.

blocks|key|1939587|text|对于这些答案，将完整的路径添加到python3和youtube-dl命令中:问题不在于在路径中找不到python3，问题是youtube-dl脚本shebang行是#!/usr/bin/env+python。最短的解决办法应该是：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1939588|python3+`which+youtube-dl`+[URL]|code-block|syntax|javascript|entityMap^0|2A|L|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|O|8|@]|D|@]|E|$I|J]]]|K|$]]

For those answers adding the full path to both python3 and youtube-dl commands: The problem is not that python3 can't be found in PATH, the problem is that youtube-dl script shebang line is <code>#!/usr/bin/env python</code>. The shortest solution should be:

this solution to youtube-dl error works for Ubuntu 18.04.02 LTS. 
(The date when I wrote this is Mar.04.2019 so please check version). 

This is the way, when using youtube-dl, I solved the following error message : 

/usr/bin/env: ‘python’: No such file or directory

<ol>
<li><code>cd /usr/bin</code></li>
<li><code>ls python</code> </li>
</ol>

This should show you what python version you have. If your python version is 3 or above just go to step 4. if your version is below python 3 go to step3. 

<ol start="3">
<li><code>sudo apt install python3</code></li>
<li><code>/usr/bin/python3.6</code> <code>/usr/local/bin/youtube-dl</code> ( your youtube video hyper link). </li>
</ol>

( in my case I had python 3.6 located in /use/bin/(whatever python version). Obviously, you have to adjust for whatever python version you have).

this should work for that stupid <code>/usr/bin/env python error on youtube-dl</code>.

I have done a clean install of 18.04 LTS.
I then installed youtube-dl using

<pre><code>sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl
</code></pre>

When I try to use youtube-dl, I get the following error message:

<pre><code>rudolffischer@HP8770w:~$ youtube-dl -U
/usr/bin/env: ‘python’: No such file or directory
</code></pre>

Python 3 seems to be installed

<pre><code>rudolffischer@HP8770w:~$ python3
Python 3.6.5 (default, Apr 1 2018, 05:46:30) 
[GCC 7.3.0] on linux
