53. To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH environment variable. Next time you log in this will be done automatically.

55. To configure your current shell run source $HOME/.cargo/env

配置

在~/.bashrc文件中增加下列内容：

1. #rust
2. export PATH=$HOME/.cargo/bin:$PATH

验证

执行rustc --version：

1. $> rustc --version
2. rustc 1.22.1 (05e2e1c41 2017-11-22)

安装openssl

如果compile时报错，找不到openssl：

1. cargo:rerun-if-env-changed=OPENSSL_DIR
2. run pkg_config fail: "`\"pkg-config\" \"--libs\" \"--cflags\" \"openssl\"` did not exit successfully: exit code: 1\n--- stderr\nPackage openssl was not found in the pkg-config search path.\nPerhaps you should add the directory containing `openssl.pc\'\nto the PKG_CONFIG_PATH environment variable\nNo package \'openssl\' found\n"

执行下列命令即可：

1. sudo apt-get install pkg-config libssl-dev
