安装失败

[yitro-z-wang]

失败位置：

./node_modules/cross-env/bin/cross-env.js NODE_ENV=production ./node_modules/webpack/bin/webpack.js --progress --colors

完整错误信息：

请问如何解决？

[hackape]

这些信息基本什么都没说…
请尝试一下把 package.json 里面 scripts.build 改为如下再试试看
"build": "NODE_ENV=production ./node_modules/webpack/bin/webpack.js --progress --colors"

[yitro-z-wang]

./ide.sh build 已经成功运行了。但是 ./ide.sh run 又出错了…

@tanhe123 你看看这个？

[tanhe123]

看报错信息是没有安装正确 java，请确保 java 正确安装、JAVA_HOME 环境变量正确配置。
如果只是体验，可以先尝试 docker 版，使用 docker run -p 8080:8080 -h webide --name webide webide/webide 即可。

[yitro-z-wang]

理论上我能正确安装 maven 的话，JAVA 的环境应当是正常的呀。JAVA 有版本要求么？

[root@localhost ~]# mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)

PS: 其实想用 Docker，奈何因为一些原因无法升级内核。

[tanhe123]

尝试执行：

cd backend
mvn spring-boot:run

然后把详细的错误信息发来吧

[yitro-z-wang]

附输出文件
mvn.txt

PS：是和那个 Atmosphere Framework 有关系？

[tanhe123]

从日志来看是启动成功了，然后被中断了，比如 ctrl+c？

当现实如下信息的时候，就可以打开浏览器，访问 http://localhost:8080 了（如果使用 ctrl+ c 会停止服务）。

运行 mvn spring-boot:run 的确出现了你描述的结果。但是我还是不能正常运行 ./ide.sh run，单运行 mvn 那句就足够了么？此外，可以修改默认开放的端口么？

[tanhe123]

1. mvn spring-boot:run 正常，打开浏览器访问下页面试试？./ide.sh run 和 mvn spring-boot:run 完成的一样的功能，使用哪种方式都可以。
2. 端口可以修改，修改方式也很多，比如使用 maven 命令：mvn spring-boot:run -Drun.arguments="--server.port=8089"，又或者使用 ./ide.sh run -p 8089

[yitro-z-wang]

刚完成 mvn 的时候试过了，页面正常（但是 Terminal > New Terminal 貌似不能用？），但是 ./ide.sh run 就会报我之前的 BUILD FAILURE

[tanhe123]

1. Terminal > New Terminal 的问题 @hackape
2. 那个错误是不全的，没看到有用的错误信息，麻烦你附一下完整的 log

[yitro-z-wang]

标准输出是这个ide.txt

这个貌似是 mvn 的错误日志(?)，也放上来吧hs_err_pid28519.txt

[vangie]

@TainKung 错误显示，内存不足

不是说 512M 可以跑的么。刚开 top 看了一下，从 611052k free 开始最后还是内存爆掉了…是过程中内存占用大了吧。说起来用 mvn 执行就没有问题。
