【解决方案1】：

请参阅https://github.com/trufflesuite/truffle/issues/4692，因此对于解决方法，我们必须...

对于非 nvm

# Install npm 6
npm i -g npm@6

# Make sure should get npm `6.14.15`
npm --version

# Should work now
npm i -g truffle

对于非虚拟机

# In case you have 16 installed (you can skip this)
npm config delete prefix

# Get npm 6.14.16 from node 14 (or you can try install only npm)
nvm use 14

# Make sure should get npm `6.14.15`
npm --version

# Should work now
npm i -g truffle
