无法在 cloud9 ide 上启动 heroku

Question

我正在运行命令 - curl https://cli-assets.heroku.com/install-ubuntu.sh | sh

这会引发以下错误 -

% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

+ dpkg -s apt-transport-https
+ echo ''
sh: line 4: /etc/apt/sources.list.d/heroku.list: No such file or directory

我还运行了sudo snap install --classic heroku，它返回了sudo: snap: command not found。

然后我运行sudo apt install snapd，它返回了以下内容-

apt: invalid flag: install
Usage: apt <apt and javac options> <source files>
where apt options include:
  -classpath <path>          Specify where to find user class files and annotation processor factories
  -cp <path>                 Specify where to find user class files and annotation processor factories
  -d <path>                  Specify where to place processor and javac generated class files
  -s <path>                  Specify where to place processor generated source files
  -source <release>          Provide source compatibility with specified release
  -version                   Version information
  -help                      Print a synopsis of standard options; use javac -help for more options
  -X                         Print a synopsis of nonstandard options
  -J<flag>                   Pass <flag> directly to the runtime system
  -A[key[=value]]            Options to pass to annotation processors
  -nocompile                 Do not compile source files to class files
  -print                     Print out textual representation of specified types
  -factorypath <path>        Specify where to find annotation processor factories
  -factory <class>           Name of AnnotationProcessorFactory to use; bypasses default discovery process
See javac -help for information on javac options.


warning: The apt tool and its associated API are planned to be
removed in the next major JDK release.  These features have been
superseded by javac and the standardized annotation processing API,
javax.annotation.processing and javax.lang.model.  Users are
recommended to migrate to the annotation processing features of
javac; see the javac man page for more information.

最后，我跑了wget 0- wget https://toolbelt.heroku.com/install-ubuntu.sh | sh，它返回了

我正在参加有关 Upskill 的在线课程，并且正在观看视频 #125。请告知如何进行。

感谢您的时间和帮助。

Answer 1

如果你没有弄清楚...

nvm i v8

接着……

npm install -g heroku

Answer 2

我有一个专门用于在 Cloud9 上设置 Rails 的要点（尽管我还没有为 Rails 6 更新它）。建议您在尝试之前通读两遍。在某些情况下，您可能需要出现故障，因为具体方法取决于您是克隆现有的存储库还是构建新的应用程序。

你可能不需要snap。

还有对 Cloud9 有用的 bash 别名： https://gist.github.com/MyklClason/d71a39ace28b9ec9f0ad

至于您的实际问题。 Heroku 工具带已过时，请改用它：

wget -qO- https://cli-assets.heroku.com/install-ubuntu.sh | sh

此外，通常最好只在线查看并检查如何使用官方文档为您的操作系统安装 heroku cli（或其他任何东西）。尽管这可能不适用于较旧的设置。但是，heroku 是您基本上必须使用最新版本的东西，否则您会遇到问题。
