注意：这个问题已部分解决，但需要更多关注。请参阅 OP 底部的注释和@Digisec 的部分答案。
我尝试在 CentOS 7 上设置 Node.js，但以下命令无法安装最新版本。 要在 CentOS 7 上安装最新版本的 Node.js，我需要更改以下代码中的哪些内容？
我首先输入node --version结果为v0.12.7.这显然是一个旧版本，因为nodejs.org说这v5.6.0是最新的稳定版本。
然后我输入以下内容来获取最新版本的node.js：
cd /tmp
curl -sL https://rpm.nodesource.com/setup | bash -
终端打印出我应该输入以下内容来删除过时的 Node.js 版本，因此我输入以下内容：
yum remove -y nodejs npm
终端还要求输入以下内容来安装最新版本的 Node.js，因此我输入以下内容：
yum install -y nodejs
但随后我node --version再次输入，终端v0.12.7再次回复 ，表明前面的命令只是再次重新安装了旧的过时版本。
那么我需要做什么才能在 CentOS 7 机器上安装最新稳定版本的 node.js 呢？
持续努力：
根据@Digisec的建议，我重新运行了上述命令，但这次将所有输出记录到以下文本中。请注意，现在我再次运行它，顺序略有不同，但结果是相同的，如下所示：
[root@localhost ~]# node --version
v0.12.7

[root@localhost tmp]# node --version
v0.12.7
[root@localhost tmp]#
然后我访问了上面错误日志引用的知识库文章，但发现我无法访问完整的文章，因为我不是 Red Had 客户。
部分解决方案：
@Digisec 通过展示如何安装新版本部分解决了这个问题，但我们仍然无法删除旧版本，这将留下未来发生冲突的风险。 需要采取哪些步骤来删除旧版本，以便新安装干净完整？
我发现旧版本 v0.12.7 的 tar url 在此链接。 @Digisec' 还建议阅读这个另一个链接，建议使用命令make uninstall。 我感觉可能只有五到十个命令可以在终端中输入来删除旧的 v0.12.7 并重新安装新版本的 nodejs。需要哪些命令？
我似乎使用以下终端命令在CentOS 7机器上找到了三个与nodejs v0.12.7相关的tar文件：
[root@localhost ~]# cd /
[root@localhost /]# find . -type f -iname "*.tar"
find: ‘./run/user/1000/gvfs’: Permission denied
./opt/node-v0.12.7/deps/npm/node_modules/tar/test/dir-normalization.tar
./opt/node-v0.12.7/deps/npm/test/fixtures/gitignore-and-npmignore-2.tar
./opt/node-v0.12.7/deps/npm/test/fixtures/gitignore-and-npmignore.tar
./usr/local/lib/node_modules/npm/test/fixtures/gitignore-and-npmignore-2.tar
./usr/local/lib/node_modules/npm/test/fixtures/gitignore-and-npmignore.tar
./usr/local/lib/node_modules/npm/node_modules/tar/test/dir-normalization.tar
[root@localhost /]#
请注意，还有另外三个 tar 文件被标记，node_modules它们之间的关系v0.12.7尚不清楚。
我需要运行哪些特定命令才能安全地从计算机中卸载v0.12.7并删除所有关联的 tar 文件？v0.12.7
答案1
我刚刚检查了关联你从那里得到这个。具体来说，您正在安装 version 0.10，或者至少正在尝试安装，但正在安装的存储库中有一个较新的版本。您必须遵循节点 v5 的设置。
curl --silent --location https://rpm.nodesource.com/setup_5.x | bash -
聚苯乙烯：为了将来的参考，请确保您非常仔细地阅读这些站点，尤其是在运行命令时根。
编辑： 好吧，看来你添加了回购协议正确。查看存储库，您的软件包在那里，但系统正在寻找错误的版本。在这一点上，我建议。
yum clean all && yum update
这将清理缓存的存储库并从远程获取。
回答：
在我们完成工作之后chat，这是给您的正确答案。nodejs v5安装得很好。您之前是nodejs v0.12手动编译的，这对于二进制发行版来说不是一个好主意，因为您最终会处于这个位置。
which node
回
/usr/local/bin/node
尽管
/usr/bin/node
返回了 的正确答案v5.x。
此时您有多种选择来修复它，但我建议使用 2。
- 选项1: 这是最简单的方法。您可以编辑
.bashrc并添加一个alias将指向的node -> /usr/bin/node。这就像添加一样简单alias node="/usr/bin/node"。这每次都会调用正确的版本，但我不能保证它将来不会与库发生冲突。 - 选项2: 虽然这个方法比较麻烦，但是还是可以解决的。首先，使用
yum系统上安装的nodejs进行清除。其次，获取已编译版本的 tarball，解压./configure并卸载它。这一步，你可以发现在线的容易地。最后，nodejs通过重新安装yum，这应该可以解决您的问题。
答案2
我做了什么：
rm -f /etc/yum.repos.d/nodesource-el* 卷曲-sL https://rpm.nodesource.com/setup_7.x |重击- yum安装-ynodejs 节点--版本
我得到了：
v7.2.0
答案3
CentOS 7.2、NodeJS 6.7.0（https://nodejs.org/download/release/v6.7.0/）。手动安装
wget https://nodejs.org/download/release/v6.7.0/node-v6.7.0.tar.gz
./configure
make
make install
卸载make uninstall
答案4
这里同样的问题。我为解决这个问题所做的是：
所有命令都必须以 root 身份执行，或者至少在每个命令的开头添加 SUDO
卸载nodejs - 在我的例子中是node v8
yum uninstall nodejs npm
从 /etc/yum.repos.d 中删除实际存储库
rm /etc/yum.repos.d/nodesource*
更新您的存储库
yum update
获取更新的存储库 - 在我的例子中为 Node v14
curl -sL https://rpm.nodesource.com/setup_14.x | bash -
我喜欢进行新的 yum 更新（这是可选的）
yum update
安装新版本的节点
yum install nodejs
享受
