无法在WebStorm中启动新的React Native CLI项目

Question

当我在终端中使用此命令时，react-native-cli正在生成项目：

react-native init myapp

但由于某种原因，WebStorm无法创建新的React Native项目。当我尝试时，我收到此错误：

/home/sagar/.nvm/versions/node/v8.9.1/bin/node 
/home/sagar/.nvm/versions/node/v8.9.1/lib/node_modules/react-native-cli/index.js init bookip
/bin/sh: 1: npm: not found
This will walk you through creating a new React Native project in /tmp/1512313270685-0/bookip

Consider installing yarn to make this faster: https://yarnpkg.com

Command `npm install --save --save-exact react-native` failed.
Done

它说npm在我知道它在那里时没有找到。

我有Node 8.9.1和npm 5.5.1

Answer 1

看起来npm不在你的$PATH上。您是从终端还是从桌面/系统菜单启动WebStorm？在后一种情况下，WebStorm只看到在.profile（登录shell）中配置的环境变量，但不在交互式shell配置文件（如~/.bashrc）中。此外，NVM仅在安装阶段改变交互式shell配置文件（https://github.com/creationix/nvm/blob/v0.28.0/install.sh#L126）

可能的解决方法：

• 解决方法1：在登录shell中提供必需的变量（即对于Bash，将它们从.bashrc移动到.bash_profile或.profile）。
• 解决方法2：从终端运行IDE
• 解决方法3：编辑WebStorm桌面启动器并将命令设置为/bin/bash -l -i -c "/path/to/webstorm.sh"（对于bash）

Answer 2

尝试指向您的usr / local / bin / node文件夹。这些是我使用WebStorm 2017.3的设置，它对我有用。

Answer 3

考虑安装纱线以加快速度：https://yarnpkg.com

纱线安装后，错误消失了。
