VirtualEnv.jl
VirtualEnv.jl provides support for creating lightweight “virtual environments” with their own site directories, isolated from system site directories. Each virtual environment has its own Julia binary (which matches the version of the binary that was used to create this environment) and can have its own independent set of installed Julia packages in its site directories.
Installation
VirtualEnv is a Julia Language package. To install VirtualEnv, please open Julia's interactive session (known as REPL) and press ]
key in the REPL to use the package mode, then type the following command
For stable release
pkg> add VirtualEnv
For current master
pkg> add VirtualEnv#master
Usage
Creation of virtual environments is done by executing the command venv
:
julia -e 'using VirtualEnv; venv("/path/to/new/virtual/environment")'
An executable is also created in your .julia
folder in .julia/bin
(The default location of this folder is ~/.julia
) which can be used for easier execution:
venv /path/to/new/virtual/environment
The help text can easily be displayed in the Julia REPL with ?venv
or by executing the command venv -h
. This shows the available options when creating new environments or upgrading existing environments.
venv
Creates virtual Julia environments in one or more target directories.
Usage
venv [options] [flags] <env_dirs>
Args
<env_dirs> One or more directories to create environments in.
Options
-p, --prompt <prompt> Provides an alternative prompt prefix for this
environment.(Default: ENV_DIR)
Flags
-c, --clear Delete the contents of the environment directory if it
alreadyexists. (Default: false)
-u, --upgrade Upgrade the environment directory to use this version
ofJulia. (Default: false)
-h, --help print this help message
-V, --version print version information
Global Installation
It is recommended to add this .julia/bin
folder to your PATH
so that the executable is available everywhere. To easily add the appropriate locations to your path, you can run the following:
julia> using VirtualEnv
julia> VirtualEnv.comonicon_install_path()
