centos 安装完 node, /usr/local/bin 下有 node 却无法执行?

    这是一个创建于 651 天前的主题,其中的信息可能已经有所发展或是发生改变。

    安装方式是通过下载编译好的 node 二进制文件来安装。

    安装:

    cd ~
    
    wget https://nodejs.org/dist/v12.18.3/node-v12.18.3-linux-x64.tar.xz
    
    sudo tar --strip-components 1 -xvJf node-v* -C /usr/local
    

    检查环境变量 /usr/local/bin 是有的:

    /usr/local/bin/node --version 可以执行,node --version 却不可以。

    
    # ls /usr/local/bin
    node  npm  npx
    
    # echo $PATH
    /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
    
    # /usr/local/bin/node --version
    v12.18.3
    
    # node --version
    -bash: /usr/bin/node: No such file or directory

    这是因为 /usr/bin/node 是一个丢失了引用的软连接,把这个删了就行

    先确认 `/usr/bin/node`是否存在。如果存在,那么检查文件类型是否正确,包括 ELF 是 32 位还是 64 位。
    如果文件不存在,那么 `hash -r`命令清空 bash 的命令路径缓存。也可以直接开始清空,毕竟 path 里 /usr/local/bin 目录比 /usr/bin 优先。

    这种自行安装的方式真的很不好,不适合初级用户,瞎装一通只是一两句也没法修。

    简单点选一个源从源里装最合适

    @swulling #7 主要是 那个什么 update 源没更新, 我一装是 node v4.2 ? 太老了 ,我又卸载了。 但是 那个 yum update 我是有阴影了, 执行一次要等很久。 而且我担心会影响到现有环境。

    1 、2 、4 、6 楼的兄弟都在说 /usr/bin/node,楼主一个劲地操作 /usr/local/bin/node,能找出问题才怪。特别是 1 楼的命令有 90% 的概率能找到问题,不知道为什么楼主选择性忽略。

    这是没找到,跟动态链接库没关系。

    ls -la `which node`
    看一下,如果不是指向 /usr/local/bin/node 直接删掉。

    如果是,关掉 shell 重新开一下。

    @leo108 #10 我想可能是打错了, /usr/bin/node 是没有的

    # ls -al /usr/bin/node
    ls: cannot access /usr/bin/node: No such file or directory


    @calmzhu #11 是指向这个 /usr/local/bin/node

    # ls -la `which node`
    -rwxr-xr-x 1 1001 1001 48646656 Jul 22 23:00 /usr/local/bin/node

    重启 shell 指的是重启 笔记本上的 终端吗, 还是服务器上面的 shell,笔记本我已经重启过了的。服务器的东西我尽量不想动, 这个上面还跑着好几个 应用的 docker 容器呢

    不用重启服务器。重启过的话。那么文件位置对的。

    看下这个文件类型。
    file /usr/local/bin/node
    看一下文件类型是 elf 还是 ascii text

    如果是 ASCII text,用文本打开看看第一行的内容。

    不用看了。之前是怀疑 node 用脚本管理。然后里面第一行指向了#!/usr/bin/node

    但是看你 ls -la 出来的大小应该是二进制。


    用 strace 跟一下调用看看

    strace node --version

    @calmzhu #16

    我试一下,node --version 又可以了,,, 记起来 我重启 mac pro 后, 没有试过 node --version 能不能用

    重启的原因其实主要是上网很慢,各种操作都卡 ssh 远程连接 阿里云服务器,wget 下载文件 node 安装包 也很慢。

    而且我在 终端里输入命令 特别的卡, 所以重启了一下, 重启后网速快多了, 而且输入也不卡顿。

    但是我奇怪的是, 我连接 阿里云服务器下载, 那个下载是 阿里云服务器去下载, 和我 mac pro 的网速有什么关系呢?

    我记得昨天 mac pro 开了很多 软件没关( IDEA 、Chrome 、Evernote 那些),就合上盖休眠了, 可能是这个原因
