【问题描述】:
我必须安装 node 和 npm。在安装之前,我做了一些搜索以寻找安装这些东西的最佳方法。我发现的是:
- 安装
nvm - 使用
nvm安装node - 设置
nvm alias default,使node默认可用。 - 在安装
node时,您还将获得npm。 - 将全局模块目录更改为
HOME内的某个路径,这样在使用npm安装全局范围 包时,您不必使用sudo。 - 使用
npm作为全局模块再次安装npm。 - 将新的全局模块目录的
bin添加到我们的$PATH环境变量中
但是在这样做之后npm 不起作用。它给出以下错误:
$ npm install -g yo
> spawn-sync@1.0.13 postinstall /Users/aapa/.node_modules_global/lib/node_modules/yo/node_modules/cross-spawn/node_modules/spawn-sync
> node postinstall
/Users/aapa/.node_modules_global/bin/yo -> /Users/aapa/.node_modules_global/lib/node_modules/yo/lib/cli.js
> yo@1.4.7 postinstall /Users/aapa/.node_modules_global/lib/node_modules/yo
> yodoctor

这是我运行的所有实际命令:
#1. Install nvm
$curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.26.1/install.sh | bash
#2. Install node using nvm
$nvm install node
# This will install the latest stable version of node. Here `node` is an alias to stable
#node -> stable (-> v0.12.7) (default)
#stable -> 0.12 (-> v0.12.7) (default)
#3. Set the nvm alias default so that the node will be available by default.
$nvm alias default node
#4. You will also get npm while installing node.
$ which npm
/Users/aapa/.nvm/versions/node/v0.12.7/bin/npm
#5. Change the global modules directory to some path inside your HOME so that while installing global scoped packages using npm you don't have to use sudo.
$ npm config get prefix
/Users/aapa/.nvm/versions/node/v0.12.7
$ cd && mkdir .node_modules_global
$ npm config set prefix=$HOME/.node_modules_global
$ npm config get prefix
/Users/aapa/.node_modules_global
$ cat .npmrc
prefix=/Users/aapa/.node_modules_global
#6. Install npm again using npm as a global module.
$ npm install npm --global
/Users/aapa/.node_modules_global/bin/npm -> /Users/aapa/.node_modules_global/lib/node_modules/npm/bin/npm-cli.js
npm@2.14.1 /Users/aapa/.node_modules_global/lib/node_modules/npm
#7. Add new global module directory's `bin` to our `$PATH` environment variable
$ echo -e '\n\n#adding npm global module location to path\nexport PATH="$HOME/.node_modules_global/bin:$PATH"' >> ~/.bash_profile
$ source ~/.bash_profile
# check
$ which npm
/Users/aapa/.node_modules_global/bin/npm
网上还有一些其他相关资源:
-
SO- NPM permission error while installing - 这里的答案建议使用
sudo我试图避免。 -
Yeoman issues - can not install yeoman on my mac running OS X Yosemite 10.10.1 - 我想我已经按照这里的解决方案做了所有事情,除了这里的解决方案使用
.bashrc,我使用了.bash_profile。
我不确定我在哪里做错了。有什么想法吗?
