| description | Use when your machine does not have JuliaLang runtime |
If your machine does not have the Julia programming language runtime installed, follow the instructions below to install it.
On macOS or Linux, run the following command:
$ curl -fsSL https://install.julialang.org | sh -s -- --yes
On Windows, run the following command in PowerShell:
PS> winget install --name Julia --id 9NJNWW8PVKMN -e -s msstore
Use this method when the curl | sh installer cannot run — for example, when a
sandbox or permission policy blocks piping a remote script directly into sh
(the "Code from External" pattern). This downloads the same official Julia
binary the installer would fetch, but as a plain file you extract locally
— no shell-pipe-to-interpreter.
Detect platform with uname -s (Linux / Darwin) and uname -m (x86_64 / aarch64 / arm64).
Pick the URL fragment matching your platform:
| OS / Arch | URL path | Tarball suffix |
|---|---|---|
| Linux x86_64 | linux/x64 | linux-x86_64.tar.gz |
| Linux aarch64 | linux/aarch64 | linux-aarch64.tar.gz |
| macOS x86_64 (Intel) | mac/x64 | mac-x86_64.tar.gz |
| macOS aarch64 (Apple) | mac/aarch64 | macaarch64.tar.gz |
Resolve the latest stable patch (see [[finding-latest-julia-version]] for
the full set of methods — do not hard-code VERSION= from memory), then
download and extract:
VERSION=$(curl -fsSL https://julialang-s3.julialang.org/bin/versions.json \
| jq -r 'to_entries | map(select(.value.stable)) | map(.key)
| sort_by(split(".") | map(tonumber? // 0)) | last')
MINOR=${VERSION%.*} # → e.g. 1.12
ARCH_PATH=linux/aarch64 # ← from table above
ARCH_SUFFIX=linux-aarch64 # ← from table above
mkdir -p ~/julia-install && cd ~/julia-install
curl -fsSLO "https://julialang-s3.julialang.org/bin/${ARCH_PATH}/${MINOR}/julia-${VERSION}-${ARCH_SUFFIX}.tar.gz"
tar -xzf "julia-${VERSION}-${ARCH_SUFFIX}.tar.gz"
export PATH="$HOME/julia-install/julia-${VERSION}/bin:$PATH"
julia --version
To persist PATH across sessions, append the export PATH=... line to
~/.bashrc, ~/.zshrc, or the appropriate shell profile.
If winget is unavailable, download the .zip package from
https://julialang.org/downloads/, extract it, and add the inner bin\ directory to PATH.
juliaup would fetch — only the delivery mechanism differs.juliaup add <version> is NOT available with this method; install another tarball to use a different version.PATH is set per-command, reference julia by full path ($HOME/julia-install/julia-<VERSION>/bin/julia) instead of relying on shell profile.
