在 ubuntu trusty 上配置飞镖 content_shell

Question

我正在尝试运行 xvfb-run -s '-screen 0 1024x768x24' pub run test -p content-shell Ubuntu Trusty。

Dart 和 content shell 安装方式如下：

# Install Dart
curl https://dl-ssl.google.com/linux/linux_signing_key.pub | gpg --import --no-default-keyring --keyring /etc/apt/trusted.gpg.d/google.gpg
curl https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list
apt-get update
apt-get install --assume-yes  dart=1.15.0-1

# Content shell and dartium
curl https://storage.googleapis.com/dart-archive/channels/stable/release/1.15.0/dartium/dartium-linux-x64-release.zip> /dartium-linux-x64-release.zip && \
    unzip /dartium-linux-x64-release.zip -d /opt/google && \
    mv /opt/google/dartium-* /opt/google/dartium && \
    chmod -R 755 /opt/google/dartium

curl http://storage.googleapis.com/dart-archive/channels/stable/release/1.15.0/dartium/content_shell-linux-x64-release.zip > /content_shell-linux-x64-release.zip && \
    unzip /content_shell-linux-x64-release.zip -d /opt/google && \
    mv /opt/google/drt-* /opt/google/content_shell && \
    chmod -R 755 /opt/google/content_shell

/opt/google/content_shell 包含在我的 PATH 变量中。

# which content_shell
/opt/google/content_shell/content_shell

然而，当我运行那个测试尝试时：

# xvfb-run -s '-screen 0 1024x768x24' pub run  test -p content-shell

我收到如下错误：

Failed to run Content Shell: Content Shell failed with exit code 1..
  dart:async                              Future.Future.error
  package:async/src/result/error.dart 30  ErrorResult.asFuture
  package:async/src/result.dart 93        Result.release.<fn>
  ===== asynchronous gap ===========================
  dart:async                              _Future.then
  package:async/src/result.dart 93        Result.release

我没有看到更多信息。我不确定这是否应该引起关注，尽管它看起来很不祥：

# content_shell --version
[1114:1114:0617/150811:9471556647:ERROR:browser_main_loop.cc(189)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.
[1116:1116:0100/000000:9471568304:ERROR:zygote_linux.cc(612)] write: Broken pipe

我的问题是如何配置内容 shell 以正确安装以便它运行测试 pub run test -p content-shell？

Answer 1

就我而言，我需要一些字体。

您可以通过查看日志文件了解 contentshell 有哪些错误，我的安装位置是：

cat /opt/google/content_shell/content_shell.log

这表明我缺少一堆字体，导致 contentshell 无声地失败。

我必须安装的那些（或 hack my way around 因为很多字体包都很大，而且因为这是一个 Docker 容器我想尽量减少膨胀）：

apt-get update && apt-get install fonts-tlwg-garuda

其中大部分来自 this source code 验证。找到它首先验证的列表而不是运行命令并看到下一个列表一百万次要容易得多。

您可能希望实际安装此软件包。
