我对 elixir 和 phoenix（和 ubuntu）很陌生，并且一直在努力让自己启动并运行 Web 开发。使用创建新的凤凰应用程序时
mix phoenix.new webapp
我从终端收到以下错误
Fetch and install dependencies? [Yn] y
* running mix deps.get
* error command failed to execute, please run the following command again after installation: "mix deps.get"
* running npm install && node node_modules/brunch/bin/brunch build
* error command failed to execute, please run the following command again after installation: "npm install && node node_modules/brunch/bin/brunch build"
和跑步时 mix deps.get
结果错误信息是
** (Mix) No package with name phoenix_ecto (from: mix.exs) in registry …运行cargo test不会显示所有 4 个测试，也不会显示我运行的任何测试的任何输出。我有4个测试：
test common::tests::test_workingdays
test documents::tests::create_docs
test emailer::tests::test_attachments
test emailer::tests::test_format_attachments
test common::tests::test_workingdays
test documents::tests::create_docs
test emailer::tests::test_attachments
test emailer::tests::test_format_attachments
它只运行其中两个，甚至没有向我提供有关失败的信息。
