Question

我拿到了我的新笔记本电脑，想要开始反应编码。

首先，我尝试创建一个react模板目录。

npm install create-react-app

create-react-app template

现在npm开始在模板路径上正常工作。

然后我将此路径复制到新路径。

cp -r template 0429

这次npm开始不起作用。这是错误。

  renderzdeMacBook-Pro:0429 renderz$ npm start

 template@0.1.0 start /Users/renderz/myproject/0429
 react-scripts start

module.js:472
    throw err;
    ^

Error: Cannot find module '../scripts/start'

npm ERR! A complete log of this run can be found in:

首先，我认为这将是＆＃39; react-scripts＆＃39;我安装了＆＃39; react-scripts＆＃39;全球化。但不能解决。

增加：

renderzdeMacBook-Pro:0429 renderz$ npm -v
4.5.0
renderzdeMacBook-Pro:0429 renderz$ node -v
v7.9.0

如果使用start.js复制项目，则手动运行cp -r脚本：

node node_modules/react-scripts/scripts/start.js

因为cp -r只复制文件内容，所以不一定保留符号链接。

npm start使用react-scripts bin文件，该文件位于./node_modules/.bin/react-scripts但是，这应该符号链接到./node_modules/react-scripts/bin/react-scripts.js。这个符号链接意味着npm可以找到cross-spawn模块，它是react-scripts的子依赖项。

cp -a将保留符号链接，以避免此问题。

希望这有帮助。
