使用sudo用户安装npm:

sudo npm install -g create-react-app 

而不是 NPM install -g create-react-a pp。

对于linux / ubuntu如果命令

NPM install -g <package_name>

npm WARN deprecated superagent@4.1.0: Please note that v5.0.1+ of superagent removes User-Agent header by default, therefore you may need to add it yourself (e.g. GitHub blocks requests without a User-Agent header).  This notice will go away with v5.0.2+ once it is released.

修复:安装与根权限

Sudo NPM install <package_name> -g

这是由于npm无法在本地运行时访问全局node_modules目录造成的

sudo chown -R Name: /usr/local/lib/node_modules

e.g.

sudo chown -R developerayo: /usr/local/lib/node_modules

修复了问题，现在您可以再次运行您运行的命令。

Brew卸载节点

Brew安装节点

Sudo NPM install -g "your_package"——not - safe-perm=true——allow-root

希望这能帮助到

解决此问题的最佳方法(因为不同设备的解决方案可能不同)是仔细阅读错误，以便找出需要写访问的文件夹。

在我的例子中，我必须给予/usr/local/lib和/usr/local/bin权限。

注意所有更改/usr/local下所有目录所有者的响应 基本上，不要破坏Linux系统!!

对于本地的东西使用sudo也是一个非常糟糕的建议。

www.competa.com的原始链接被破坏了，所以这是原始的方法:

npm config set prefix ~/.npm

# open your .bashrc (Linux) or .bash_profile (Mac) file for editing:
nano ~/.bashrc # for Linux
# or...
nano ~/.bash_profile # for Mac if you haven't created a .bashrc file

# add these lines:
export PATH="$PATH:$HOME/npm/bin"
export NODE_PATH="$NODE_PATH:$HOME/npm/lib/node_modules"

# save the file and then enter this command or logout and login to make the changes take effect:
. ~/.bashrc
# or...
. ~/.bash_profile

选项B:使用NVM之类的版本管理器
