sudo ${which npm} run xxx我记得当我需要 root 权限来运行 npm 时，我能够使用类似的东西。它是什么？
希望这是发布的正确论坛。即将到来的堆栈溢出，但我认为这更多的是你们的专业知识。
我有一个 centos 6.10 盒子。它的 Node.js 和 npm 运行正常。我不知道他们是哪个版本的。我试图通过运行将它们更新到 LTS
sudo npm install n -g
现在，每当我运行时，npm我都会收到此错误：
node: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by node)
node: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by node)
node: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.5' not found (required by node)

node: /lib64/libc.so.6: version `GLIBC_2.17' not found (required by node)
node: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by node)
我试图完全卸载 node 和 npm 并重新安装它们，也没有运气。现在我没有技巧了。有人可以帮我解决我现在应该做什么吗？
我正在尝试为一个简单的反应应用程序设置一个 systemd 服务。此应用程序托管在 /home/myuser/test 中。npm 和 node 都在 PATH 中并且硬链接到 /usr/bin。所有文件都具有 myuser:myuser 用户和组的权限。如果我手动启动npm start它，它会正确启动并从http://localhost:3000
Compiled successfully!
You can now view test in the browser.
Local: http://localhost:3000
On Your Network: http://myipaddress:3000
Note that the development build is not optimized.
To create a production build, use npm run build.
如果我尝试通过 systemd 启动应用程序，它会失败但没有说明原因。我使用相同的用户从相同的路径启动它，并尝试了 ExecStart 可以想象的所有组合：
ExecStart=npm start
ExecStart=/usr/bin/npm start
ExecStart=/usr/bin/node /home/myuser/test/node_modules/react-scripts/scripts/start.js
它们都产生相同的结果，即它“开始”正常，并且在它失败后不久，在 journalctl 中显然没有理由：
$sudo systemctl status node-client

我在 journalctl 上不断收到以下信息

systemd 服务文件随着时间的推移发生了变化，但无论 ExecStart 和其他更改如何，错误都是相同的，这是目前的内容：
[Unit]
Description=Node-React Frontend Server
After=syslog.target network.target
[Service]
ExecStart=/usr/bin/node node_modules/react-scripts/scripts/start.js
Restart=always
RestartSec=10s
TimeoutSec=900
User=myuser
Group=myuser
Environment=PATH=/usr/bin:/usr/local/bin
WorkingDirectory=/home/myuser/test/
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nodeclient
[Install]
WantedBy=multi-user.target
操作系统是Centos7。所有测试都是使用相同的用户完成的，没有 sudo，手动和通过 systemd 使用相同的命令。手动启动有效，systemd 无效。
最后，提一下，我通过 systemd 拥有 Express-NodeJS 应用程序，并且它使用相同的 systemd 配置正确启动。它只对 React 失败。
任何帮助将不胜感激！
谢谢

我已经在我的服务器上安装了“让我们聊天”。在文档中，他们说要启动应用程序
npm start
从安装应用程序的目录。
但我无法使用 systemd 启动它。我希望应用程序始终在线。所以如果我手动启动它就可以了
cd /MIDDLE/uow/lets-chat/ && /bin/npm start
但如果我从 systemd 配置 Execstart 中的行，则不会。我尝试使用同一行，我尝试使用 npm，我尝试使用 "node ./apps.js" ：
ExecStart=/usr/bin/cd /MIDDLE/uow/lets-chat/ && /usr/local/bin/node /MIDDLE/uow/lets-chat/app.js
（我尝试使用或不使用命令的绝对路径，但它没有任何改变）。
我不知道如何在我的 centos 中将这个应用程序作为守护进程启动。请问我该怎么办？
谢谢，

我正在尝试在我的 Debian 服务器上安装 Laravel，但在安装node-sass. 我有这个设置很长时间了，以前从未遇到过问题。也许node-sass或npm最近改变了什么？
希望你能帮助我，我已经卡了2天了。

我已经清理了我的运行npm remove ...并npm -g remove ...删除了与npm. 但是当我尝试时我仍然遇到错误npm install generator-webapp

知道如何解决吗？我搜索了一段时间，唯一的建议是清理我的npm包裹。
