我也是尝试

sudo npm install express
npm install -g express
sudo npm install -g express

没有任何工作。

推荐答案

Node手动安装非常方便。我喜欢这样做，因为它真的很容易切换版本。

Node is so easy to install manually. I like doing it this way too because it's really easy to switch versions.

这也是伟大的，因为你不需要添加一些外部包存储库到 apt ，并且当节点发布新版本时，您不必等待这些存储库更新。一旦发布，您就可以获得更新。

This is also great because you don't need to add some external package repository to apt, and you don't have to wait for those repositories to update when node releases a new version. You can get updates as soon as they're released.

# make a `~/.nodes/ folder
mkdir -p ~/.nodes && cd ~/.nodes

# download the binaries from nodejs.org
# in this case, here's the linux version
curl -O http://nodejs.org/dist/v0.10.12/node-v0.10.12-linux-x64.tar.gz

# extract
tar -xzf node-v0.10.12-linux-x64.tar.gz

# rename folder to 0.10.12
mv node-v0.10.12-linux-x64 0.10.12

# create a `current` symlink
ln -s 0.10.12 current

# prepend ~/.nodes/bin to your path
# you'll want to save this in ~/.bashrc or ~/.zshrc or something
export PATH="~/.nodes/current/bin:$PATH"

# cleanup
rm ~/.nodes/node-v0.10.12-linux-x64.tar.gz

最好的部分是你可以重复任何其他版本的节点的模式，随时更改当前符号链接，以切换您正在运行的版本，并且您很好去

---

The best part about this is you can repeat the pattern for any other version of node, change the current symlink at any time to switch which version you're running, and you're good to go

% node --version
v0.10.12

% npm --version
1.2.32

# switch versions to (e.g.) 0.10.5
% cd ~/.nodes && rm current && ln -s 0.10.5 current

% node --version
v0.10.5

% npm --version
1.2.18

编写可执行脚本时的其他指针

Additional pointers when writing executable scripts

创建可执行文件

% touch ~/somefile && chmod +x ~/someifle && nano ~/somefile

文件内容

#!/usr/bin/env node
console.log(process.version);

运行

% ./somefile
v0.10.12
