Question

我一直在尝试使用react native并创建一个项目，但却无法这样做。

我正在使用https://facebook.github.io/react-native/docs/getting-started.html

中的说明

节点和守望者已经安装，然后我输入：

npm install -g react-native-cli

我明白了：

/usr/local/bin/react-native -> /usr/local/lib/node_modules/react-native-cli/index.js
react-native-cli@1.0.0 /usr/local/lib/node_modules/react-native-cli
├── semver@5.3.0
├── minimist@1.2.0
├── chalk@1.1.3 (ansi-styles@2.2.1, escape-string-regexp@1.0.5, supports-color@2.0.0, has-ansi@2.0.0, strip-ansi@3.0.1)
└── prompt@0.2.14 (revalidator@0.1.8, pkginfo@0.4.0, read@1.0.7, winston@0.8.3, utile@0.2.1)

当我尝试做的时候：

react-native init AwesomeProject

我明白了：

如何防止错误？

我正在使用Mac。

我在命令的开头使用了sudo。但是当我这样做的时候：

cd AwesomeProject
react-native run-ios

我得到了：

fs.js:640
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

Error: EACCES: permission denied, open '/Users/jaimito/.babel.json'

    at run (bootstrap_node.js:394:7)
    at startup (bootstrap_node.js:149:9)

我在开始时尝试使用sudo，我得到了这个：

fs.js:640
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

Answer 1

尝试使用sudo启动命令，它将为您的命令提供在必要位置创建目录的权限。

Answer 2

如果您使用的是Windows，请尝试使用管理员权限打开命令行。

如果你在mac或linux上，请在命令开头输入sudo。

无论哪种方式。确保目标目录不存在。

Answer 3

对我来说，marked目录中的.npm目录属于root:wheel。尝试将其取回;）（或0.3.*内的marked目录）

chown -R `whoami` ~/.npm/marked

或者必要时

sudo chown -R `whoami` ~/.npm/marked
