错误: EACCES:权限被拒绝，请打开'/root/.config/truffle/config.json‘

Question

无法更正尝试安装松露时的EACCESS问题。

是的，我最初是通过sudo安装npm的，而不是nvm，但这已经被更正了，-unless，谁知道是什么--根据网站。

这个路径实际上并不存在，所以我根据一个git问题创建了它：

/root/.config/truffle/

[root@home config]# ls -la |grep truffle
drwxrwxr-x. 2 root root   6 Jul 14 17:08 truffle

[user@home ~]$ nvm --version
0.34.0

$ npm -v
6.9.0

已将完全权限分配给node_modules

ll|grep node
drwxrwxrwx. 31 user user 4096 Jul 14 16:58 node_modules

我尝试了这个链接中的一个建议：Permission denied when installing npm module。

以太坊SE中的用户在Ubuntu issue上遇到此问题。

浏览了以下链接，并为package- npm notice created a lockfile as package-lock.json. You should commit this file提供了完全权限，以防出现问题

已尝试强制清除npm缓存。

这个github用户显然是通过使用sudo：truffle compile error (EACCES: permission denied) on V5 w/ Linux #1212解决了这个问题。

还尝试以root用户身份进行安装。

$ sudo npm install -g truffle

Answer 1

我遇到了这个问题，不仅仅是松露，其他模块也是如此。对我来说，至少这个帖子中列出的其他解决方案是有效的，但它们有一个副作用，那就是我只能以超级用户身份运行truffle。我知道这可能有点草率，但我的解决方案是将.config目录中所有文件的所有权更改为我的用户。为了实现这一点，我做了以下工作：

sudo chown myUsername:myUsername -R ~/.config

如果您想对此更加小心，您可以选择运行

sudo chown myUsername:myUsername ~/.config

sudo chown myUsername:myUsername ~/.config/truffle

sudo chown myUsername:myUsername ~/.config/truffle/config.json

这样做之后，我就可以运行sudo npm i -g truffle了。这是我之前遇到的所有问题的快速解决方案，我希望它能为你工作！

Answer 2

当安装truffle时，在高山上构建容器时也会发生这种情况，我可以使用以下方法修复该问题；

npm i -g --unsafe-perm=true --allow-root truffle

Dockerfile

FROM node:10.17.0-alpine

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

RUN apk add -t .gyp --no-cache git python g++ make \
    && npm i -g --unsafe-perm=true --allow-root truffle \
    && apk del .gyp

ENTRYPOINT ["truffle"]

在我最初的尝试中，通过npm i -g truffle全局安装也会导致相同的EACCES错误。
