npm install:在 node-sass@3.13.1 安装后脚本失败

npm install: Failed at the node-sass@3.13.1 postinstall script

我有一个 angular 申请:https://github.com/XBITSwitzerland/ngx-admin/tree/ng2-admin

现在我尝试做:npm install

但是我得到这个错误(命令的竞争输出太长,所以我只在这里分享最后一部分):

有人知道为什么会出现此错误以及如何解决吗?

我认为这是因为您缺少 node-sass 模块。尝试以下操作并重新运行您的构建脚本,看看是否能解决您的问题:

npm install node-sass@latest

此外,我看到您在 Windows 平台上使用 fsevents,只是警告此模块仅支持对 OS X FSEvents[=12= 的本机访问]

如果您运行遇到这个问题,请阅读此页面:https://www.bramvandenbulcke.be/en/kb/failed-node-sass3131-postinstall-script

我的解决方案:

1) 删除 package-lock.json 文件

2) npm install gulp-sass --save-dev

3) npm install node-sass@latest

版本特定说明:

node-sass@3.13.1 运行s 仅适用于 Node.js v7 版本,如 release notes 中所述:

收到此消息后我在 npm 安装上遇到错误 node-sass@3.13.1 postinstall: node scripts/build.js

并花了数小时寻找解决方案。我试图将它安装在使用旧版本节点和 npm 的 laravel 5.2 上,这对我有帮助

$ npm install -g n
$ n 6.10.2    // selecting version you need in my case 6.10.2
$ npm install -g npm@3.10.10 // same for npm

希望这对其他人有帮助^_^

#######更新###########

nvm install 6.10.2
nvm use 6.10.2
npm install -g npm@3.10.10

我也收到同样的错误

"npm 错误!代码 ELIFECYCLE 错误!错误号 1 npm 错误!节点-sass@3.13.1 安装后:node scripts/build.js 错误!退出状态 1 错误! 错误!在 node-sass@3.13.1 安装后脚本失败。 错误!这可能不是 npm 的问题。上面可能有额外的日志输出。"

解法:

我将 node-sass 和 gulp-sass 版本增加到 package.json 文件中的最新版本,然后问题得到解决。

仅删除

package-lock.json

文件

再做一次npm install

对我来说,问题出在 Linux 目录权限上。即使使用 sudo 和 root 用户我也无法让它工作。

我的解决方案是更改项目目录所有者,如下所示:

sudo chown my_user:my_user -R /path/to/project 

分别执行以下命令:

rm -rf package-lock.json

npm install node-sass@latest

如果您在错误输出中进一步向上滚动,您会看到如下内容:

gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2

您可以通过以下步骤在 windows 上修复它:

  1. 删除 node_modules 文件夹
  2. 运行 npm install --global windows-build-tools在 powershell 中作为管理员
  3. 正在使用 npm install
  4. 重新安装节点模块或节点-sass

对于Ubuntu

  1. 删除包-lock.json文件

  2. sudo npm install gulp-sass --save-dev

  3. sudo npm install node-sass@latest

如果您使用 Visual Studio 运行 以下命令:

npm cache clean --force
 npm config set msvs_version 2019 --global

其中 2019 是 Visual Studio

的版本

如果您正在使用 OpenBSD,那是因为您需要 g++。使用

安装
pkg_add g++

但是,它作为 ec++ 安装在 /usr/local/bin,因此您可以复制、重命名或 使用以下方法创建符号链接

ln -s /usr/local/bin/ec++ /usr/local/bin/g++

再次执行 npm install,它应该可以工作
