I always install virtualenvwrapper to help out. From the shell prompt:

<pre><code>pip install virtualenvwrapper
</code></pre>

There is a way documented in the virtualenvwrapper documents - <a href="https://virtualenvwrapper.readthedocs.org/en/latest/command_ref.html?highlight=cpvirtualenv#cpvirtualenv" rel="noreferrer">cpvirtualenv</a>
This is what you do. Make sure you are out of your environment and back to the shell prompt. Type in this with the names required:

<pre><code>cpvirtualenv oldenv newenv
</code></pre>

And then, if necessary:

<pre><code>rmvirtualenv oldenv
</code></pre>

To go to your newenv:

<pre><code>workon newenv
</code></pre>

<h2>In Python 3.3+ with built-in venv</h2>
As of Python 3.3 the <code>virtualenv</code> package is now built-in to Python as the <code>venv</code> module. There are a few minor differences, one of which is the <code>--relocatable</code> option has been removed. As a result, it is normally best to recreate a virtual environment rather than attempt to move it. <a href="https://stackoverflow.com/a/58772116/6501141">See this answer</a> for more information on how to do that.
What is the purpose behind wanting to move rather than just recreate any virtual environment? A virtual environment is intended to manage the dependencies of a module/package with the venv so that it can have different and specific versions of a given package or module it is dependent on, and allow a location for those things to be installed locally.
As a result, a package should provide a way to recreate the venv from scratch. Typically this is done with a <code>requirements.txt</code> file and sometimes also a <code>requirements-dev.txt</code> file, and even a script to recreate the venv in the setup/install of the package itself.
One part that may give headaches is that you may need a particular version of Python as the executable, which is difficult to automate, if not already present. However, when recreating an existing virtual environment, one can simply run python from the existing venv when creating the new one. After that it is typically just a matter of using pip to reinstall all dependencies from the <code>requirements.txt</code> file:
From Git Bash on Windows:
<pre class="lang-sh prettyprint-override"><code>python -m venv mynewvenv
source myvenv/Scripts/activate
pip install -r requirements.txt
</code></pre>
It can get a bit more involved if you have several local dependencies from other locally developed packages, because you may need to update local absolute paths, etc. - though if you set them up as proper Python packages, you can install from a git repo, and thus avoid this issue by having a static URL as the source.

blocks|key|843707|text|对我有效的更简单的解决方案:只需将旧虚拟环境的site-packages文件夹复制到新的虚拟环境中。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|843708|entityMap^0|N|D|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I've created folder and initialized a virtualenv instance in it.

<pre><code>$ mkdir myproject
$ cd myproject
$ virtualenv env
</code></pre>

When I run <code>(env)$ pip freeze</code>, it shows the installed packages as it should.

Now I want to rename <code>myproject/</code> to <code>project/</code>.

<pre><code>$ mv myproject/ project/
</code></pre>

However, now when I run

<pre><code>$ . env/bin/activate
(env)$ pip freeze
</code></pre>

it says pip is not installed. How do I rename the project folder without breaking the environment?

Renaming a virtualenv folder without breaking it

Visual Studio

Windows

Python

我已经创建了一个文件夹，并在其中初始化了一个virtualenv实例。$ mkdir myproject$ cd myproject$ virtualenv env当我运行(env)$ pip freeze时，它会正常显示已安装的包。现在我想将myproject/重命名为project/。$ mv myproject/...
