# bootstrap_jiri initializes a root directory for jiri.  The following
# directories and files will be created:

#   /.jiri_root              - root metadata directory
#   /.jiri_root/bin/jiri     - jiri binary
#
# The jiri sources are downloaded and built into a temp directory, which is
# always deleted when this script finishes.  The  is deleted on any
# failure.

A typical bootstrap workflow looks like this:

$ export PATH=myroot/.jiri_root/bin:$PATH
$ cd myroot

  exit 1

最初のダウンロードで発生したエラー:
Updating all projects
ERROR: Creating project "fuchsia": 'git fetch https://fuchsia.googlesource.com/fuchsia +refs/heads/*:refs/remotes/origin/*' failed:

stderr:

ネットワークの問題かもしれませんが、もう一度実行すればいいです.
次のエラーも発生しました.
Updating all projects
ERROR: context deadline exceeded

なぜか分かりませんが、ディレクトリの下のコードは同期済みです.一時的に無視
ダウンロード時間が長く、問題が発生する可能性があります.shellスクリプトでupdateを使用できます.
#! /bin/bash

# make_sure_update.sh

while true; do
	jiri update -v && break
done


 
環境変数にjiriを宣言します.
export PATH=$PATH:$(pwd)/.jiri_root/bin
その後jiri updateを使用してコードを更新できます.
