问题描述

在npm install命令上引发以下警告-

Following warning is being thrown on npm install command -

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.2 (node_modules\rea
ct-scripts\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@
1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}
)
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\ch
okidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@
1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}
)

该警告显然正在导致我们的詹金斯工作标记为失败，因此我们只是在试图摆脱同样的情况.

The warning is apparently causing our Jenkins Job to mark failed, so we are just trying to get rid of the same.

我已经检查了此 https://stackoverflow.com/a/42938398/351903 但是，与那里提到的不同，我的设置中没有任何/node_modules/fserrors.另外，我的package.json不包含fserrors.以下是我的package.json-

I already checked this https://stackoverflow.com/a/42938398/351903 But, unlike what is mentioned there, I do not have any /node_modules/fserrors in my setup. Also, my package.json does not contain fserrors. Following is my package.json -

更新

我尝试运行npm install命令并获取较早命令的退出状态.尽管显示警告，但显示为0表示成功.因此，看起来Jenkins的工作不会因此而停滞.但是，我们仍在设法摆脱这种警告，因为它与我们的操作系统无关.

I tried running the npm install command and getting the exit status of the earlier command. It showed 0 meaning success, despite the warnings. So, it does not look like Jenkins job should be stuck due to this. However, we are still trying to find a way to get rid of this warning because it is not relevant to our OS.

推荐答案

fsevents在Mac和其他Linux系统中的处理方式有所不同. Linux系统会忽略fsevents，而Mac会安装它.如上述错误消息所述，fsevents是可选的，并且在安装过程中被跳过.

fsevents is dealt differently in mac and other linux system. Linux system ignores fsevents whereas mac install it. As the above error message states that fsevents is optional and it is skipped in installation process.

您可以在Linux系统中运行npm install --no-optional命令，以避免出现以上警告.

You can run npm install --no-optional command in linux system to avoid above warning.
