错误：“brew链接”步骤未成功完成

Question

我试图通过Homebrew安装node.js。不幸的是，我得到了这个错误：

➜  ~  brew install node
==> Downloading http://nodejs.org/dist/v0.8.10/node-v0.8.10.tar.gz
######################################################################## 100.0%
==> ./configure --prefix=/usr/local/Cellar/node/0.8.10
==> make install
==> Caveats
Homebrew installed npm.
We recommend prepending the following path to your PATH environment
variable to have npm-installed binaries picked up:
  /usr/local/share/npm/bin
Warning: Could not link node. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link node'
==> Summary
/usr/local/Cellar/node/0.8.10: 856 files, 13M, built in 103 seconds

然后我尝试手动链接节点...

➜  ~  brew link node
Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking...

Error: Could not symlink file: /usr/local/Cellar/node/0.8.10/lib/node_modules/npm/scripts/relocate.sh
Target /usr/local/lib/node_modules/npm/scripts/relocate.sh already exists. You may need to delete it.
To force the link and delete this file, do:
  brew link -f formula_name

To list all files that would be deleted:
  brew link -n formula_name

运气不好，所以我试着强行连接节点...

➜  ~  brew link -f node
Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking...

Error: Permission denied - /usr/local/lib/dtrace/node.d

我对dtrace在任何方面都不熟悉，我害怕弄乱权限，所以我尝试了sudo。。

➜ ~ git:(master) sudo brew link -f node
Password:
Error: Cowardly refusing to `sudo brew link'
You can use brew with sudo, but only if the brew executable is owned by root.
However, this is both not recommended and completely unsupported so do so at
your own risk.

我尝试通过brew卸载节点卸载节点并重试安装，但没有运气。

Answer 1

sudo chown -R $(whoami) /usr/local 

就像Brew网站故障排除中提到的那样

Answer 2

node.js的自制软件包现在又包含了npm，所以当我错过了自制软件包关于先删除独立版本的消息时，我就遇到了这种情况。

假设，像我一样，您已经通过尝试升级破坏了节点/npm，然后才知道先卸载npm-g，您可以rm-rf /usr/local/lib/node_modules/npm，然后brew link节点。这将删除独立的自托管npm包（而不是brew想要安装的包），并让brew符号链接其从Cellar捆绑的包。

Answer 3

我运行Mac OS X Mavericks。我尝试安装节点0.10.25和顶部的答案不适合我。

natevw说要rm-rf /usr/local/lib/node_modules/npm，但是如果/usr/本地/lib/node_modules上的权限是这样的：

drwxr-xr-x   3 root      admin   102 Feb  2 20:45 node_modules

然后brew将无法在该目录中创建其npm符号链接。这是我的解决方案：

$ brew update

根据您过去安装node/npm的方式，其中一些命令是不必要的。

$ brew uninstall npm
$ brew uninstall node
$ npm uninstall npm -g
$ sudo rm -rf /usr/local/lib/node_modules

注意：我有杂散的节点文件，我发现运行brew-v链接节点（这给了我连结错误brew抱怨冗长的输出）。您可能需要：

$ sudo rm -rf /usr/local/include/node
$ sudo rm -rf /usr/local/lib/node

$ brew install node
