npm script, copy package.json to dist when bundling
提问by ajmajmajma
I am trying to add a second part to my npm bundle script. The first part runs great, however I am trying to copy in 3 files along with the bundle.
我正在尝试将第二部分添加到我的 npm 包脚本中。第一部分运行良好，但是我试图将 3 个文件与捆绑包一起复制。
So right now I have :
所以现在我有：
"bundle": "NODE_ENV=production webpack --output-file bundledFile.js && cp package.json dist/",
The NODE_ENV=production webpack --output-file bundledFile.jsworks great by itself. The part that is not working is the && cp package.json dist/, I would like the script to copy my package.json (along with 2 other files actually, but just starting with this one) to the dist folder. Brand new to these scripts, any idea how to fix? Appreciate any advice, thanks!
在NODE_ENV=production webpack --output-file bundledFile.js通过自身的伟大工程。不起作用的部分是&& cp package.json dist/，我希望脚本将我的 package.json（实际上还有其他 2 个文件，但只是从这个文件开始）复制到 dist 文件夹。这些脚本是全新的，知道如何修复吗？感谢任何建议，谢谢！

The syntax should work (and seems to, looking at your comments). I would suggest splitting your npm scripts across multiple points, though:
语法应该可以工作（并且似乎可以查看您的评论）。不过，我建议将您的 npm 脚本拆分为多个点：
{
"bundle": "NODE_ENV=production webpack --output-file bundledFile.js",
"copy": "cp package.json dist/ && cp README.md dist/ && cp .npmrc dist/",
"build": "npm run bundle && npm run copy"
}
In order to be cross-platform compatible (cpis not typically available on windows), I would also suggest adding a build file somewhere such as ./tools/copy-distrubution-files.jswhich would make use of fsto copy the necessary files, then call it in the npm scripts with node ./tools/copy-distribution-files.js. That will be (mostly) platform independent (you still have to assume that nodeis available as the nodejs executable, but that seems fairly reasonable to me).
为了跨平台兼容（cp通常不适用于Windows），我也建议增加一个构建文件的地方，例如./tools/copy-distrubution-files.js它会利用fs到复制必需的文件，然后把它与故宫的脚本node ./tools/copy-distribution-files.js。这将（主要）独立于平台（您仍然必须假设它node可用作 nodejs 可执行文件，但这对我来说似乎相当合理）。

If you're running on windows use the following command:
如果您在 Windows 上运行，请使用以下命令：
"copy": "copy "package.json" "dist" && copy "README.md" "dist" && copy ".npmrc" "dist"
copy instead of cp. Don't forget to use ""for each path. and if you need to define a long path, don't use / (slashes) but \ (backslashes)
复制而不是cp。不要忘记对每个路径使用""。如果你需要定义一个长路径，不要使用 /（斜杠）而是 \（反斜杠）
like:
喜欢：
copy "devices\VS-88UT\index.html" "devices\VS-88UT\dist"
Also, if you prefere ther is a nice pluginto run bash command before and after each build
此外，如果您更喜欢，有一个很好的插件可以在每次构建之前和之后运行 bash 命令

To copy folders and files in windows just use
要在 Windows 中复制文件夹和文件，只需使用
xcopy git\* dist\ /e /i /h
I think this might help someone.
我认为这可能会帮助某人。

The quickest way for me was to reference powershell in a package.json script like this:
对我来说最快的方法是在 package.json 脚本中引用 powershell，如下所示：
"copyFile": "@powershell copy './source/package.json' './deploy'",
