Google gn的主页指定二进制下载链接https://chrome-infra-packages.appspot.com/dl/gn/gn/linux-amd64/+/latest。我尝试使用 Ansibleunarchive下载、解压和安装这个 zip 存档：

- name: Unpack gn Ninja meta-build for Android and ChromeOS into /usr/bin/
  become: yes
  unarchive:
    src:  https://chrome-infra-packages.appspot.com/dl/gn/gn/linux-amd64/+/latest
    remote_src: yes
    exclude: .cipdpkg
    dest: /usr/bin
    mode: 0755

Ansible 似乎检测到这是一个 zip 存档，但给出了错误：

An exception occurred during task execution. To see the full traceback, use -vvv.
The error was: ValueError: time data '19800000.000000' does not match format '%Y%m%d.%H%M%S'

使用 Python 2.7 也同样失败。

zip 存档中文件的时间确实是19800000.000000，这表明这是 zip 存档的问题：

$ wget https://chrome-infra-packages.appspot.com/dl/gn/gn/linux-amd64/+/latest
$ zipinfo -s -T latest
Archive:  latest
Zip file size: 887558 bytes, number of entries: 2
-r-x------  2.0 unx  2101112 bl defN 19800000.000000 gn
-r--------  2.0 unx      141 bl defN 19800000.000000 .cipdpkg/manifest.json
2 files, 2101253 bytes uncompressed, 887304 bytes compressed:  57.8%

虽然 Ansibleunarchive无法提取存档，但unzipshell 命令可以。所以首先使用下载存档get_url，然后使用提取它unzip：

- name: Create a temporary download directory
  tempfile:
    state: directory
  register: tempdir

- name: Download gn
  become: yes
  get_url:
    url:  https://chrome-infra-packages.appspot.com/dl/gn/gn/linux-amd64/+/latest
    dest: "{{ tempdir.path }}/gn-linux-amd64.zip"

- name: Extract gn
  become: yes
  command:
    cmd: /usr/bin/unzip -o "{{ tempdir.path }}/gn-linux-amd64.zip" gn -d /usr/bin
    warn: false    # Suppress suggestion to use unarchive

- name: Make gn executable
  become: yes
  file:
    path: /usr/bin/gn
    mode: 0755

这有效，但文件gn仍然有一个不太可能的时间戳：

$ ls -l /usr/bin/gn
-rwxr-xr-x 1 root root 2101112 Dec 31  1979 /usr/bin/gn

向 Yuji Konishi 致敬，他在Ansible 问题 35686 中正确指出问题出在 zip 存档中。
