usage: rush install [-h] [-p] [--bypass-policy] [--no-link] The "rush install" command installs package dependencies for all your projects, based on the shrinkwrap file that is created/updated using "rush update". (This "shrinkwrap" file stores a central inventory of all dependencies and versions for projects in your repo. It is found in the "common/config/rush" folder.) If the shrinkwrap file is missing or outdated (e.g. because project package.json files have changed), "rush install" will fail and tell you to run "rush update" instead. This read-only nature is the main feature: Continuous integration builds should use "rush install" instead of "rush update" to catch developers who forgot to commit their shrinkwrap changes. Cautious people can also use "rush install" if they want to avoid accidentally updating their shrinkwrap file. Optional arguments: -h, --help Show this help message and exit. -p, --purge Perform "rush purge" before starting the installation --bypass-policy Overrides enforcement of the "gitPolicy" rules from rush. json (use honorably!) --no-link If "--no-link" is specified, then project symlinks will NOT be created after the installation completes. You will need to run "rush link" manually. This flag is useful for automated builds that want to report stages individually or perform extra operations in between the two stages.
