I often forget it, so make a note
Since it will be installed in the environment you use, describe that environment.
| Middleware | version |
|---|---|
| OS | macOS Sierra |
| Python | 3.6.1 |
| pip | 9.0.1 |
| virtualenv | 15.0.1 |
Since the basics are important, the method described in the official document is implemented virtualenv -Installation
Before the installation procedure, there are about 3 notes, so if you take a look
--It is recommended to install virtualenv-1.9 or above. Prior to 1.9, the pips contained in virtualenv were not downloaded from PyPI over SSL. --If you use pip to install virtualenv, we recommend that you use pip 1.3 or higher. Prior to version 1.3, pip was not downloaded from PyPI over SSL. --easy_install wasn't downloaded from PyPI over SSL and was corrupted in some subtle way, so it's recommended that you don't use easy_install to install virtualenv when using setuptools 0.9.7.
It seems that automatic translation is strange, but this time I will skip it because it seems that I do not have to worry about it.
Here we will install using pip.
$ [sudo] pip install virtualenv
Execute the following command
$ virtualenv --version
15.1.0
Since the version is displayed properly, it seems that it is installed correctly.
