npm无法处理版本#中的引导0--“npm版本补丁”未被识别--导致“npm !ERR``` `”

Question

我使用节点7.10.1 (它有NPM4.2.0)。我运行在Windows7 SP1上。

在过去的其他项目中，我使用了以下方法来修改我的package.json中的版本号：

• git add .
• git commit - m "reason for change"
• npm version patch

这在我做过的其他3个项目中是无缝的。

现在，当我在当前项目上运行这个程序时，会得到以下错误/输出：

> npm version patch
npm ERR! npm version [<newversion> | major | minor | patch | premajor | preminor | prepatch | prerelease | from-git]
npm ERR! (run in package dir)
npm ERR! 'npm -v' or 'npm --version' to print npm version (4.2.0)
npm ERR! 'npm view <pkg> version' to view a package's published version
npm ERR! 'npm ls' to inspect current package/dependency versions

package.json可以很好地完成它的所有其他任务(构建、安装等)。尽管在上面显示的输出的第二行中有指示，但我在包目录根目录级别(与package.json相同的目录)中运行该命令。

我的package.json中有什么是npm version patch不喜欢的吗？这个错误没有告诉我出了什么问题，更不用说如何修复它了。当地的回购版似乎没问题。我甚至删除和重新克隆它，认为我可能有一些问题，在本地，但没有改变。

通过这个错误，我能清楚地看到的只有npm !ERR，其馀的输出似乎毫无意义。我通过国家预防机制在全球范围内安装的唯一工具是：

npm list -g --depth=0
C:\Users\myuser\AppData\Roaming\npm
+-- electron@1.7.6
`-- gulp-cli@1.3.0

下面是我的package.json，以防有什么问题.

Answer 1

(贴出我想出的答案)

问题是版本号字段中有前导零。

事实证明，package.json 中的version字段在其任何部分都不能有前导零。具体来说，在我的package.json中，我有以下内容：

{
... ... ..
  "version": "0.01.19",
... ... ..
}

这就是导致这个命令的原因。

npm version patch

若要产生错误：

npm ERR! npm version [<newversion> | major | minor | patch | premajor | preminor | prepatch | prerelease | from-git]
npm ERR! (run in package dir)
npm ERR! 'npm -v' or 'npm --version' to print npm version (4.2.0)
npm ERR! 'npm view <pkg> version' to view a package's published version
npm ERR! 'npm ls' to inspect current package/dependency versions

修复方法是将package.json文件中的version字段更改为：

{
... ... ..
  "version": "0.1.19",
... ... ..
}

虽然我发现了这个问题是很好的，但是当这个错误发生时，npm并没有产生有用的信息。实际上，无法调试所产生的错误消息所发生的事情。这应该由npm来改变。在此之前，请注意不要在package.json中允许前导零。
