无法在Mac Sierra上安装Elasticsearch（10.12.2）(Unable to install Elasticsearch on Mac Sierra (10.12.2))

尝试通过启动Elasticsearch 5.1.1时

$ elasticsearch

我得到输出：

Error: Could not find or load main class -Xms2g

我调查过：

我读过如何调用类可能是一个错误？但我没有接触到这样做。这个线程没有帮助，并不是我的问题，因为我没有安装插件。

我通过Homebrew安装。以下是一些输出：

$ brew info elasticsearch elasticsearch: stable 5.1.1, HEAD Distributed search & analytics engine https://www.elastic.co/products/elasticsearch Conflicts with: elasticsearch@1.7, elasticsearch@2.4 /usr/local/Cellar/elasticsearch/5.1.1 (98 files, 35.2M) * Built from source on 2016-12-14 at 09:23:56 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/elasticsearch.rb ==> Requirements Required: java >= 1.8 ✔ ==> Caveats Data: /usr/local/var/elasticsearch/elasticsearch_GabbAHH/ Logs: /usr/local/var/log/elasticsearch/elasticsearch_GabbAHH.log Plugins: /usr/local/Cellar/elasticsearch/5.1.1/libexec/plugins/ Config: /usr/local/etc/elasticsearch/ plugin script: /usr/local/Cellar/elasticsearch/5.1.1/libexec/bin/plugin To have launchd start elasticsearch now and restart at login: brew services start elasticsearch Or, if you don't want/need a background service you can just run: elasticsearch $ brew doctor Please note that these warnings are just used to help the Homebrew maintainers with debugging if you file an issue.

我还尝试通过手动提取.tar.gz包进行最初的安装。我起初得到了一些Java权限被拒绝的错误，但是在为自己运行一个chown给管理员之后我也得到了同样的Error: Could not find or load main class类型错误。

我刚刚将Java JDK更新到最新版本：1.8.0_112并将JAVA_HOME变量相应地设置为该目录。

最新版本的Elasticsearch 2（2.4.3）可以使用。同时，Elasticsearch v5.0.2失败了。

如何在我的Mac上正确安装Elasticsearch？

When attempting to start Elasticsearch 5.1.1 via

$ elasticsearch

I get the output:

Error: Could not find or load main class -Xms2g

I've looked into:

I read it may be an error in how a class is called? But I'm not exposed to doing that. This thread doesn't help and isn't really my problem as I'm not installing a plugin.

I installed via Homebrew. Here is some output from that:

$ brew info elasticsearch elasticsearch: stable 5.1.1, HEAD Distributed search & analytics engine https://www.elastic.co/products/elasticsearch Conflicts with: elasticsearch@1.7, elasticsearch@2.4 /usr/local/Cellar/elasticsearch/5.1.1 (98 files, 35.2M) * Built from source on 2016-12-14 at 09:23:56 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/elasticsearch.rb ==> Requirements Required: java >= 1.8 ✔ ==> Caveats Data: /usr/local/var/elasticsearch/elasticsearch_GabbAHH/ Logs: /usr/local/var/log/elasticsearch/elasticsearch_GabbAHH.log Plugins: /usr/local/Cellar/elasticsearch/5.1.1/libexec/plugins/ Config: /usr/local/etc/elasticsearch/ plugin script: /usr/local/Cellar/elasticsearch/5.1.1/libexec/bin/plugin To have launchd start elasticsearch now and restart at login: brew services start elasticsearch Or, if you don't want/need a background service you can just run: elasticsearch $ brew doctor Please note that these warnings are just used to help the Homebrew maintainers with debugging if you file an issue.

I also tried originally installing via manually extracting the .tar.gz package. I at first got some Java permission denied errors, but after running a chown to admin for myself I also got this same Error: Could not find or load main class type error.

I just updated my Java JDK to the latest: 1.8.0_112 and set my JAVA_HOME variable to that directory accordingly.

The most recent version of Elasticsearch 2 (2.4.3) works. Meanwhile, Elasticsearch v5.0.2 fails.

What can I do to have Elasticsearch properly installed on my Mac?
