我正在遵循以下指南：https://neo4jrb.readthedocs.io/en/v10.0.1/Setup.html#generating-a-new-app
尝试通过运行以下方式设置环境变量：
$ export NEO4J_DIST=http://dist.neo4j.org/neo4j-community-4.4.8-unix.tar.gz但没有运气。
这是追踪日志。
$ rake neo4j:install[community-4.4.8,development] --trace

这似乎是库neo4j-rake_tasks.的一个问题。如果检查堆栈跟踪引用的行，就会发现以下代码：
def fetch(message)
require 'open-uri'
open(@url,
content_length_proc: lambda do |total|
create_progress_bar(message, total) if total && total > 0
end,
progress_proc: method(:update_progress_bar)).read
end这是老Ruby (< 2.4)。过去，在需要open-uri之后，可以使用open打开一个URL，就像打开一个文件一样。您可以看到它不再起作用，因为您得到的错误表明它试图打开一个实际的文件(或其他一些本地IO对象)。现在的方式应该是使用URI.open，而不仅仅是open。
图书馆似乎不再被维护，所以你必须自己处理这件事。
