npm - 权限被拒绝覆盖或删除节点目标

Question

我遇到了一个问题，每次我尝试运行 npm install 命令时，我都会收到一个错误:'-bash: npm: command not found'
所以我尝试使用自制软件卸载并重新安装 node 和 npm，但仍然遇到一些错误。卸载两者后，我运行了命令:“brew doctor”，我得到“您的系统已准备好进行 brew”。

首先我尝试安装节点:“brew install node”，但我得到以下信息:

==> Downloading https://homebrew.bintray.com/bottles/node-

0.12.7.yosemite.bottle
Already downloaded: /Library/Caches/Homebrew/node-0.12.7.yosemite.bottle.tar.gz
==> Pouring node-0.12.7.yosemite.bottle.tar.gz

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/systemtap/tapset/node.stp
Target /usr/local/share/systemtap/tapset/node.stp
already exists. You may want to remove it:
  rm '/usr/local/share/systemtap/tapset/node.stp'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

To list all files that would be deleted:
  brew link --overwrite --dry-run node

Possible conflicting files are:
/usr/local/share/systemtap/tapset/node.stp
/usr/local/lib/dtrace/node.d
Warning: The post-install step did not complete successfully
You can try again using `brew postinstall node`
==> Summary

那么我尝试删除目标:

Jamess-MacBook-Pro:~ jamesbradley$ rm 
'/usr/local/share/systemtap/tapset/node.stp'
override rw-r--r--  root/admin for /usr/local/share/systemtap/tapset/node.stp? y
rm: /usr/local/share/systemtap/tapset/node.stp: Permission denied
Jamess-MacBook-Pro:~ jamesbradley$

我得到以下信息:

rm: /usr/local/share/systemtap/tapset/node.stp: Permission denied

所以然后我尝试覆盖并收到此错误:

Linking /usr/local/Cellar/node/0.12.7... 
Error: Could not symlink share/systemtap/tapset/node.stp
/usr/local/share/systemtap/tapset is not writable.
Jamess-MacBook-Pro:~ jamesbradley$ 

我也尝试过 brew postinstall node 并得到以下响应:

Error: Permission denied - /usr/local/lib/node_modules/npm
Jamess-MacBook-Pro:~ jamesbradley$ 

我还尝试运行了许多其他命令:

sudo chown -R `whoami` /Library/Caches/Homebrew/
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

但似乎没有任何效果。

有谁知道我如何获得删除权限和/或如何使这些文件可写，以便我可以覆盖或删除它们？

Answer 1

删除文件夹

sudo rm -rf /usr/local/share/systemtap/

如果需要，请删除之前安装的所有节点。

brew uninstall node

然后重新安装节点

brew install node

我有同样的问题，为我工作。
