How to fix “IOError: [Errno 2] No such file or directory” when making Virtual Environments

问题

Whenever I try to use the 'virtualenv VirtualEnvironmentName' command or the 'virtualenv -p python3.8 VirtualEnvironmentName' command it says "IOError: [Errno 2] No such file or directory." I just want to make Virtual Environments, but I always get that error saying "No such file or directory." Thanks in advance.

To create a virtual environment, you must specify a path.

Then you can activate the python environment by running the following command:

your_working_directory\\Scripts\\activate

Most likely, the problem is that you're using a relative path for the directory.

Let me clarify how Python finds files:

An absolute path is a path that starts with your computer's root directory, for example 'C:\Python\scripts..' if you're on Windows.

A relative path is a path that does not start with your computer's root directory, and is instead relative to something called the working directory. You can view Python's current working directory by calling os.getcwd().

Other common mistakes that could cause a "file or directory not found" error include:

You may be using escape sequences in a file path:

    path = 'C:\Users\apps'

    Incorrect! The '\n' in 'Users\apps' is a line break character!

To avoid making this mistake, you can use any one of the below methods:

use raw string literals
```
   path = r'C:\Users\apps'
```
you can always use this:
```
 'C:/Users/apps'
```
another possibility is:
```
'C:\\Users\\apps
```
