从 SSH 触发时，Npx 返回未找到命令 [英] Npx returns command not found when triggered from SSH

问题描述

我在 SO 上发现了很多类似的问题，但遗憾的是它们与我的问题无关.

I found quite a lot of similar questions on SO, but they sadly aren't related to my issue.

我安装了带有 NVM 的 Node.

I have Node installed with NVM.

$ node -v
v14.16.0

$ npm -v
7.7.6

$ npx -v
7.7.6

我正在编写一个部署脚本，它将从我们的存储库运行 git pull，然后(除其他外)编译资产.如果这有帮助，工作环境是 Laravel 8，但我认为这与我的问题无关.

I'm writing a deployment script that will run git pull from our repository, then (among other things) compile the assets. If this helps, the work environment is Laravel 8, but I don't think it's related to my issue.

运行 npm install &&npm run prod 以远程服务器上的用户身份登录时将完美运行.但是，通过 SSH 运行相同的命令会返回以下内容:

Running npm install && npm run prod while logged as the user on the distant server will work flawlessly. However running the same command via SSH returns the following:

jaeger@local-computer~$ ssh deploy@distant-server-with-nvm-node-npm-npx '/bin/sh -c "node -v && npm -v && npx -v && exit"'


Connecting...
v14.16.0
7.7.6
/bin/sh: 1: npx: not found

所以……我迷路了.我已经看到有关 node 和/或 npm 被识别的问题，但没有关于 npx，我需要它与 Laravel 混合.当然，从远程服务运行上述注释会完美运行.

So... I'm lost. I've seen questions about node and/or npm being recognized, but none about npx, and I need it with Laravel mix. Of course, running the above comment from the distant service will work perfectly.

• 将 PermitUserEnvironment yes 添加到/etc/ssh/sshd_config，然后重新启动 ssh
• 通过 npm i -g npx 全局安装 npx，被 nvm 拒绝，说明 npx 已经存在.
• 重新安装 nvm 和节点.
• 在 /home/myuser/.nvm/versions/v14.16.0/bin/npx 和 /usr/local/bin
之间创建符号链接

• Adding PermitUserEnvironment yes to /etc/ssh/sshd_config, then restarting ssh
• Installing globally npx via npm i -g npx, got denied by nvm, stating that npx already exists.
• Réinstalling nvm and node.
• Create a symlink between /home/myuser/.nvm/versions/v14.16.0/bin/npx and /usr/local/bin

我还能尝试什么?提前致谢

What else can I try? Thank you in advance

推荐答案

最有可能的是，nvm 已将自身安装在您的 .bashrc 中，但是您触发了一个不同的shell (sh).即使 /bin/sh 指向 bash，也会禁用 rcfile - 请参阅下面的说明.直接使用bash.

Most likely, nvm has installed itself in your .bashrc, but you're triggering a different shell (sh). Even if /bin/sh points to bash, this disables using the rcfile - see explanation below. Use bash directly.

请注意 bash 手册页的摘录:--norc

Note this excerpt from bash manpage: --norc

如果 shell 是交互式的，不要读取和执行系统范围的初始化文件/etc/bash.bashrc 和个人初始化文件 ~/.bashrc.如果 shell 作为 sh 调用，则默认情况下此选项处于启用状态.

Do not read and execute the system wide initialization file /etc/bash.bashrc and the personal initialization file ~/.bashrc if the shell is interactive. This option is on by default if the shell is invoked as sh.

这意味着除了通过 - 指定命令外，您还需要使用标志 -i 强制 bash 作为 交互式 shell 运行c.

This means you'll need to force bash to be run as an interactive shell using the flag -i, in addition to specifying the command via -c.
